What weather is too bad to fly in?

Heavy snow or blizzards can make landing and taking off too dangerous, while lightning storms can be very hazardous to any aircraft. Extreme heat can also interfere with an aircraft's performance, so in hotter parts of the world, extreme temperatures can cause significant delays.

Reduced visibility, associated with cloud, mist, fog, or sand storms, can make safe flight difficult or even impossible, even with the help of technology (Instrument Landing System (ILS), weather radar, synthetic vision systems, etc)

What can cause a cancellation? Flights may be canceled due to wind, precipitation, fog or low visibility, lightning, low clouds, or storms.

MORE DETAILS

Jet aircraft can safely fly over thunderstorms only if their flight altitude is well above the turbulent cloud tops. The most intense and turbulent storms are often the tallest storms, so en route flights always seek to go around them.

Can a plane take off in a thunderstorm? Technically, it is possible, but pilots and air traffic experts prefer to keep planes on the ground when a storm is present and wait for it to calm down before setting off. Also read: Is It Safe to Fly With an Ear Infection?

While high winds (a crosswind above 40 mph and a tailwind above 10 mph) can occasionally prevent planes from taking off or landing on time, winds won't put your flight in any danger.

Turbulence, caused by rapidly changing wind speeds and directions, can be quite uncomfortable for passengers and may cause anxiety. Severe turbulence within a thunderstorm can not only be unsettling but can also cause damage to the airplane. Another risk associated with thunderstorms is lightning strikes.

Winter has strong winds and blizzards, and summer's hot heat can create unstable air, thunderstorms, and tropical storms. That means flying during the holidays often means more turbulence than other times of the year. So if possible, avoid flying between December and February or June and August for a smoother flight.

With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing.

Planes can and do land during thunderstorms, but it all depends on the situation. Pilots will often use their judgment and experience to decide if a landing is safe or not while a storm is going on. The main risk with landing during a storm, just like with taking off, is microbursts.

MORE DETAILS

There is no single maximum wind speed that cancels flights, as it depends on the direction of wind and phase of flight. A crosswind above about 40mph and a tailwind above 10mph can start to cause problems and stop commercial jets from taking off and landing.

MORE DETAILS

Turbulence might occur during your flight in rainy weather due to the presence of different air masses mixing together and causing disturbances aloft. Warm and cold air masses interacting with each other can result in turbulent conditions high in the sky, making your flight potentially more uncomfortable.

It's actually done deliberately to make sure that the plane reaches the ground safely. If the pilot has to land the aircraft while it is pouring with rain, get ready for a bumpy landing. The reason behind it is quite simple actually. A plane has a limited amount of runway zone where to land.

Sometimes it's unavoidable to fly through light and moderate turbulence, but rest assured your pilots are working to find smooth air. If they encounter severe or extreme turbulence not forecasted, pilots will quickly climb or descend to a safe and smooth altitude.”

MORE DETAILS

Severe turbulence can cause a plane to drop so suddenly that pilots temporarily lose control. But, again, that's not enough to crash the plane. That's not to say it's never happened. In 1966, human error and turbulence combined to bring a plane down over Mount Fuji.

Answer: Pilots use onboard weather radar to remain clear of thunderstorms during day and night operations. Lightning is actually easier to see at night, which shows the pilots the location of the storm.
