Although we’ve been spending a ton of money doing R&D on our weather-controlling device… it hasn’t succeeded. Hot air ballooning is highly dependent on weather conditions, and Seattle, with its diverse weather patterns, is no exception. During the Washington State flying season from April through October, hot air balloons typically do not fly in inclement weather conditions such as rain, fog, high winds, excessive heat, or in the vicinity of thunderstorms. This article should be entertaining and explain why hot air balloon flights are sometimes canceled due to various weather.

What Makes for Good Weather in Hot Air Ballooning?
The best weather for hot air ballooning? It’s a mix of clear skies, calm winds, and comfortable temperatures. These elements work together to make your flight smooth, safe, and unforgettable.
What Does Perfect Weather Look Like?
- Calm Winds: Light winds under 10 mph with no gusts make for an easy launch and gentle steering.
- Mild Temperatures: Somewhere between 50-85°F feels just right for both passengers and the balloon.
- Clear Visibility: No fog or low clouds—you want those amazing views, right?
Most flights happen at sunrise or just before sunset. Why? That’s when the winds are calmest and easiest to predict.

Why Barometric Pressure Matters
Balloons love steady or rising barometric pressure. It keeps the atmosphere stable, making for a smooth and safe ride. When the weather cooperates like this, you’re in for an incredible experience.
What Is Considered Poor Weather For Hot Air Ballooning
Not every day is made for ballooning. Some weather conditions make flying unsafe, and in Seattle, pilots take those very seriously.
What Kind of Weather Stops Flights?
- Rain: It’s bad for the balloon’s fabric and usually signals unstable weather.
- Fog: Makes it hard for pilots to see hazards like powerlines.
- Strong Winds: Even a gentle gust can turn a launch into a wrestling match.
- High Temperatures: They mess with the balloon’s performance and can make flights uncomfortable.
- Thunderstorms: Pilots steer clear of storms by at least 100 miles—it’s just not worth the risk.
What About Those Deceptively Nice Days?
Sometimes, the sky is blue, and it seems perfect for flying. But up in the air, winds or other factors could make it unsafe. That’s where pilots, with their deep knowledge and love of weather nerdiness, step in to make the call. Their goal is always the same: your safety and an amazing experience.
Why Are Hot Air Balloon Rides Canceled Sometimes?
Let’s start with the not-so-obvious reasons hot air balloon rides are canceled for weather.
Strong Winds: A Hot Air Balloon’s Biggest Challenge
Wind is one of the most critical factors in hot air ballooning. It affects every stage of the flight—launching, steering, and landing. When winds are too strong, it’s simply not safe to fly.
Why Strong Winds Are a No-Go
Hot air balloons won’t launch if surface winds exceed 10 mph. Why? Because the balloon fabric acts like a massive sail in windy conditions. During inflation, the wind can cause the balloon to whip and thrash, making it extremely difficult—and dangerous—to control.
How Wind Impacts Flight
- During Launch: High winds make inflating and stabilizing the balloon challenging.
- While Steering: Pilots rely on upper and lower winds to guide the balloon. If upper winds are too fast, the balloon might drift toward unsuitable landing areas.
- At Landing: Low-level gusts can make landing tricky. Pilots aim for wide, open spaces free of obstacles, livestock, or hazards.
Preparing for Fast Wind Landings
If winds exceed 10 mph during landing, passengers are trained for fast wind landing positions:
- Hold tight and brace for impact.
- Expect a bumpy or tip-over landing, which is safe if instructions are followed.
Fast landings can even be fun—like a bit of added adventure at the end of your flight!
Pilots are highly skilled professionals who spend years mastering weather analysis. Their decisions are guided by safety and expertise, ensuring a safe and memorable experience for every passenger.
Launching a Hot Air Balloon in Windy Conditions
Remember being a kid and tossing your jacket onto a chain-link fence on a windy day? Now imagine that jacket is a ten-story-tall hot air balloon made of fabric. In strong winds, that balloon turns into a giant sail, whipping back and forth as it’s inflated. It’s not an easy job!
Why Launching in Wind Is Tricky
Hot air balloons struggle to launch safely when surface winds exceed 10 mph or when gusts are present. During inflation, the wind can make the balloon thrash from side to side, making it difficult—and sometimes impossible—to control.
Can Balloons Fly on Windy Days?
The short answer is yes, but only under the right conditions:
- The winds must stay within the manufacturer’s limitations and have a large enough area for the flight.
- The pilot’s personal skillset and comfort level play a big role.
Launching in windy weather requires experience, precision, and a solid understanding of how to safely handle the balloon.
Dreaming of Becoming a Pilot?
If you’re inspired by the idea of mastering the skies, you can find more information about earning your pilot certificate. Piloting a balloon is a rewarding challenge that starts with understanding the art and science behind these incredible flights.
Steering To A Suitable Landing Location
Hot air balloons don’t have steering wheels, so pilots rely entirely on the upper and lower winds to steer them. At Seattle Ballooning, we fly within a 12-mile radius, which means pilots must carefully plan every flight to ensure they land in a safe and accessible area.
Why Wind Direction and Speed Matter
For a smooth and safe landing, the winds at altitude need to:
- Be manageable: If the winds are too fast, controlling the descent becomes more challenging.
- Go in a logical direction: Winds should guide the balloon toward open, obstacle-free areas.
Pilots analyze wind predictions from the ground up to 10,000 feet before every flight. However, due to Class B airspace restrictions, our balloons are limited to flying at or below 5,000 feet in altitude. This makes understanding lower wind layers even more important when navigating the skies.
Landing A Hot Air Balloon
Landing a hot air balloon is as much an art as it is a science. There are two types of landings, and both are perfectly safe when handled by a skilled pilot. If you are curious about where hot air balloons land, or why they fly low sometimes, here is a more in-depth article.
Types of Balloon Landings
- Stand-Up Landings: The basket and balloon remain upright upon touching down.
- Tip-Over Landings: More common in windy conditions, where the basket tips onto its side during the landing process.
Safety Comes First
Safety is always the top priority when landing. Pilots carefully choose landing sites that are:
- Free of obstacles like powerlines or trees.
- Clear of livestock or sensitive areas.
- Spacious enough to ensure a smooth descent.
Fast Wind Landings
In winds exceeding 10 mph, passengers are briefed on fast wind landing positions, which involve bracing for impact to ensure everyone’s safety. While it’s possible to land in winds over 17 mph, it comes with additional risks, and such landings require exceptional precision and experience.
A Handy Rule of Thumb
If a hot air balloon is launched in faster wind conditions, there’s a good chance the landing will be more dynamic—think of it as a little added adventure!

Hot Air Balloons Never Fly In Thunderstorms
Let’s face it—if there’s lightning or severe weather, ballooning is a definite no-go. Thunderstorms aren’t just a minor inconvenience; they’re a major hazard for all aircraft, including hot air balloons.
Why Thunderstorms Are Dangerous
Hot air balloon pilots avoid thunderstorms for several critical reasons:
- Strong Winds and Turbulence: These can make the flight uncontrollable.
- Outflow Winds: Invisible horizontal streams of air from the base of a storm can reach speeds of 30-40 mph, making it impossible to maintain safe control of the balloon.
The 100-Mile Rule
To stay safe, pilots don’t fly within 100 miles of a thunderstorm. Even if a storm is far away, its outflow can cause dangerous wind conditions in the surrounding area.
How Pilots Stay Ahead of the Weather
Balloon pilots are trained to:
- Monitor live radar and weather forecasts.
- Analyze wind speeds, storm activity, and other atmospheric data.
- Make real-time decisions to prioritize the safety of passengers, crew, and equipment.
When thunderstorms are in the area, the safest call is to stay grounded. After all, nothing is worth risking the safety of everyone involved.
If It’s Too Hot, You Can’t Fly
Hot weather and hot air ballooning just don’t go hand in hand. Not only does the heat make it uncomfortable for passengers, but it also creates significant challenges for the pilot and the balloon itself.
Does It Get Cold at Altitude?
Surprisingly, no! While temperatures typically drop by about 3°F for every 1,000 feet of altitude (a concept known as the lapse rate), this doesn’t always apply in hot weather. On top of that, the balloon’s powerful 20-30 million BTU burners add even more heat, raising the temperature in the basket by 10-15°F. So, even at higher altitudes, it can feel quite toasty.
Why Hot Weather Makes Flying Difficult
- Sluggish Performance: Hot air is less dense, which means the balloon needs more heat to generate enough lift. This can make the balloon feel heavy and harder to control.
- Unpredictable Winds: High temperatures can cause thermals, gusts, and erratic wind patterns as hot air pockets rise and mix with cooler air masses.
- Passenger Comfort: Let’s face it—being in a basket that’s already warm and then dealing with extra heat from the burners isn’t exactly pleasant.
Safety Always Comes First
When the mercury rises too high, the safest choice is to cancel the flight. Pilots prioritize both safety and passenger comfort, ensuring that every ride is as enjoyable and secure as possible. Hot air ballooning is about creating amazing memories—not sweating through them!
Flying A Balloon With A Cold Front Approaching Seattle? Not the best idea…
Flying a Balloon with a Cold Front Approaching Seattle? Not a Good Idea
When a cold front is on the way, flying a hot air balloon becomes a risky proposition. Why? Because cold fronts are often accompanied by fast winds and sudden weather changes—conditions that make ballooning far from ideal.
What Exactly Is a Cold Front?
A cold front is the dividing line where a cooler air mass pushes into and overtakes a warmer one. This process often brings:
- Strong Winds: Particularly near the center of the low-pressure system.
- Rapid Weather Changes: Cooler, drier air behind the front often follows clouds and showers.
- Temperature Shifts: Sudden drops in temperature that can affect air stability.
How Pilots Monitor Cold Fronts
In Seattle, pilots take a wide-angle view when evaluating the weather. They assess conditions across a broad area, including:
- North to Vancouver, Canada
- East to Idaho
- South to Portland, Oregon
By analyzing low-pressure systems and weather data, pilots make well-informed decisions about whether it’s safe to fly. If there’s even a hint of unsafe conditions, flights are grounded. Safety always comes first.
Why Cold Fronts Are a Challenge
Cold fronts often generate fast winds, which can make flying and landing unpredictable. These winds, combined with temperature changes and unstable air, pose significant risks. For passengers and crew alike, the best choice is to wait for calmer skies.
Hot air ballooning is about enjoying the serenity of the skies—not battling the chaos of turbulent weather. That’s why experienced pilots take extra precautions when cold fronts are on the horizon.
Can A Hot Air Balloon Fly In The Rain?
Unlike fixed-wing aircraft, hot air balloons don’t handle rain well. While airplanes can power through wet weather, rain poses a unique set of challenges for balloons—and it’s just not safe.
Why Rain Is a No-Go
- Damage to Balloon Fabric: Rain can degrade the balloon’s fabric over time, reducing its durability and performance.
- Unstable Weather: Rain usually comes with other unsafe conditions, like gusty winds and low visibility.
- Moisture and Heat: The burners, which heat the air inside the balloon, don’t mix well with water, potentially affecting their efficiency.
Safety Comes First
As professional commercial pilots, we don’t take chances with wet weather. In Seattle, if we see radar pops or thick, moisture-heavy clouds, we ground the balloons. It’s all about ensuring a safe and enjoyable experience for everyone on board.
Hot air ballooning is about capturing the magic of the skies—and that magic can’t happen when it’s raining.
Low Clouds, Onshore Flow, and Fog: Challenges for Hot Air Balloons
Flying a hot air balloon under low clouds or in foggy conditions isn’t just unpleasant—it’s unsafe. Hot air balloons, like all aircraft, are governed by FAA visual flight rules (VFR), which set strict guidelines to ensure safety.
What Are the FAA Rules for Clouds?
- No flying through clouds: Pilots must maintain visibility.
- Distance requirements: Balloons must stay 500 feet below or 1,000 feet above clouds.
While balloons can legally fly under clouds at 1,500-2,000 feet in Class G or E airspace, it’s not ideal for the experience. Most people flying with Seattle Ballooning want a clear view of Mt. Rainier—and clouds can block that magical sight.
Why Fog Grounds Balloons
Fog poses significant hazards for hot air balloons:
- Visibility issues: It makes it impossible to spot powerlines or other obstacles.
- Radar limitations: Fog doesn’t usually show up on radar, making it harder to predict.
- Formation: Fog occurs when the temperature and dewpoint are the same, creating a blanket of low visibility.
Staying Ahead of the Weather
Pilots use tools like the Washington Weather Discussion, supported by the University of Washington, to monitor fog, onshore flow, and low clouds. These insights help them decide whether it’s safe to fly.
Flying is all about enjoying the beauty of the skies, and clear conditions make all the difference. When clouds or fog roll in, it’s a sign to wait for better weather.
Why Else Do Hot Air Balloon Rides Get Canceled Besides the Weather?
While weather is the most common reason for hot air balloon cancellations, there are other factors at play. At the heart of every decision is the safety of our passengers, pilots, and crew.
Pilots Are Human, Too
Our pilots are incredibly skilled, but they’re not superheroes. Sometimes flights are canceled because:
- Health Issues: Pilots may feel unwell or too fatigued to ensure a safe flight.
- Instincts: Experienced pilots trust their gut—if something doesn’t feel right, they don’t fly.
- Life Happens: Like anyone else, pilots face unexpected personal challenges that may impact their ability to focus fully on the flight.
Safety Is Always the Priority
The choice to fly or cancel is ultimately up to the pilot. As a company, we stand behind their decisions 100%. It’s better to wait for a day when everyone feels confident about the flight than to take unnecessary risks.
Hot air ballooning is all about creating magical experiences—but only when it’s safe to do so. Rest assured, when you fly with us, safety comes first, always.
