Turbulence map and tracker: where to see the bumps before you fly
The free turbulence maps pilots and passengers can open today, what their colors and numbers mean, why a big jet feels less than the map suggests, and how to check your own route calmly.
Search for a turbulence map and you land on screens built for pilots: colored blobs, flight levels, numbers with strange units. They can look alarming, especially the night before a flight. They don't need to. Once you know what a turbulence map shows, and what it doesn't, it becomes one of the most reassuring things you can look at: proof that the bumps are known in advance and that crews plan around them.
Practical answer
- For your own flight, use a route forecast. Our free turbulence forecast draws your route on a map, colored by expected bumpiness at the time you'll be over each point.
- For the big picture over the US, open the Aviation Weather Center map. Its Turbulence layer is the official US forecast guidance, free and public.
- For what pilots are feeling right now, look at pilot reports (PIREPs). They're the closest thing to a live turbulence tracker.
- Read the level, then the altitude. Most areas are light or moderate, a comfort matter. Airliners cruise roughly between 30,000 and 40,000 feet, so bumps at other heights may not concern you.
- Check twice, then stop. Once two or three days out, once the day before. Refreshing every hour feeds the worry, not the plan.
The free turbulence maps you can open today
The Aviation Weather Center map (US and nearby oceans)
The US National Weather Service runs the Aviation Weather Center, whose Graphical Forecasts for Aviation cover the United States (including Alaska and Hawaii), the Gulf and Caribbean, and parts of the Atlantic and Pacific. Its Turbulence layer shows the Graphical Turbulence Guidance, usually called GTG. You choose a flight level and the map colors the areas where turbulence is expected, with separate layers for clear-air turbulence, mountain wave turbulence and turbulence near storms.
According to the FAA's turbulence program, GTG runs several turbulence algorithms, checks each one against real reports from aircraft, and weighs them into a single forecast. Over the continental US it updates every hour with forecasts up to 18 hours ahead; a global version updates every 6 hours and looks up to 48 hours ahead. The FAA also notes that GTG is most accurate where there is more traffic and in daylight, simply because more aircraft are reporting.
This is the map behind most of the "turbulence map USA" screenshots you see shared online. It's built for pilots and dispatchers, so it shows every altitude and every aircraft size. That's why it can look busier than your flight will feel.
Pilot reports: the real-time tracker
The Aviation Weather Center also publishes pilot reports, short messages in which crews describe the turbulence they actually met: where, at what altitude, how strong. On the map, they appear as small symbols along busy routes. Modern aircraft also send automatic turbulence measurements, and the FAA describes a "nowcast" that blends the latest forecast with these reports and with weather radar to refresh the picture every 15 minutes over the US.
If you want to understand how crews use these reports to step around rough air, read how pilot turbulence reports work. The short version: every report from a plane ahead becomes a smoother ride for the planes behind.
Turbulence apps
Several phone apps package forecast data into a simpler map, and some add calming tools for nervous flyers. We compared them, fact by fact from their public store listings, in the best turbulence apps in 2026.
Our route forecast
Most maps show a whole region at one altitude. A nervous flyer usually wants something narrower: my flight, my date, my timing. That's what our turbulence forecast does. You enter your departure and arrival airports and the date; it follows your great-circle route, reads the global GFS weather model at cruise altitudes for the hour your plane should be over each point, and draws the route colored from smooth to rough patches, with a minute-by-minute timeline and the winds at takeoff and landing. It's a forecast built from public weather model data, not a live tracker of aircraft, and it's free with no sign-up.
How to read a turbulence map without scaring yourself
Colors are levels, and levels are about comfort
Turbulence maps use the same intensity words pilots use in their reports: light, moderate, severe, extreme. From your seat, light means drinks ripple; moderate means firm bumps, the seatbelt sign comes on and the service pauses. Both are routine for the aircraft. Severe turbulence is rare and is where crews put most of their planning effort, and extreme is mostly found inside strong storms that pilots fly around. Our guide to reading a turbulence forecast goes through each level in detail.
The numbers are EDR, and they depend on the size of the plane
The Aviation Weather Center map shows a number called EDR (eddy dissipation rate). It measures how turbulent the air itself is, whatever flies through it. How that air feels depends on the aircraft. The Aviation Weather Center's own help page lists separate thresholds by weight class. On a medium jet like an A320 or 737, a value of 20 (on the map's ×100 scale) starts to count as moderate; on a heavy wide-body like a 777, 747 or A330, moderate only starts at 24, and severe at 54 rather than 44.
In plain words: the bigger the plane, the less a given patch of air moves it. If you're crossing an ocean on a wide-body, a yellow area drawn for all aircraft often means a lighter ride for you.
Check the altitude
Airliners cruise roughly between 30,000 and 40,000 feet. A map set to a low flight level shows bumps that you will only cross for a few minutes during climb or descent, if at all. On the Aviation Weather Center map, choose a level in that cruise band to see what concerns your flight.
A colored area is a possibility
A forecast area means the ingredients for turbulence are there: strong wind shear near the jet stream, air flowing over mountains, storm clouds. It doesn't mean every plane in it will feel bumps. Turbulence comes in patches far smaller than the colored zones, and crews change altitude when the planes ahead report rough air.
Why a map is reassuring, once you know who reads it
Every flight you take is planned with these maps and more. Dispatchers look at turbulence forecasts before the flight, pilots receive updates and reports from other aircraft on the way, and they ask air traffic control for a smoother altitude when they need one. The FAA notes that fatal turbulence accidents involving large airlines are exceedingly rare; what injures people is being unbuckled at the wrong moment. That's why the FAA's advice to passengers comes down to one habit: keep your seatbelt fastened whenever you're seated.
So the most useful way to read a turbulence map is as a schedule, not a warning. If the bumpy stretch is two hours in, plan your walk and your meal before it, have a breathing exercise or a meditation ready for it, and know that it will pass. For the bigger question of what turbulence can and can't do to a plane, read is turbulence dangerous?.
How to check your flight in three steps
- Two or three days before, enter your flight in our turbulence forecast to see the general pattern on your route.
- The day before, check once more: forecasts become much more reliable within 48 hours. If you're flying over the US, you can compare with the Aviation Weather Center map at a cruise flight level.
- Then put the map away. Choose a seat over the wing if you can (see the best seat for turbulence), note roughly when the bumps may come, and leave the rest to the crew.
Frequently asked questions
Is there a live turbulence map I can watch during my flight?
Not one that shows exactly what your plane will feel. Pilot reports on the Aviation Weather Center site are near real time, but they show where other aircraft met turbulence, at their altitude, minutes or hours ago. Your crew has better and more current information than any public map, and they use it to find smoother air.
What is the best free turbulence map?
For the US and nearby oceans, the Aviation Weather Center's Graphical Forecasts for Aviation are the official, free forecast guidance. For a single flight anywhere in the world, a route forecast like ours is easier to read because it only shows your path, at your timing.
What does EDR mean on a turbulence map?
EDR, or eddy dissipation rate, is a measure of how turbulent the air is, independent of the aircraft. The same EDR value feels lighter on a heavy wide-body than on a small jet, which is why the Aviation Weather Center lists different thresholds by aircraft weight.
Why does the turbulence map look worse than my flight felt?
Maps cover large areas and many altitudes, and they show where turbulence is possible, not where it will hit you. Pilots also pick the smoothest available altitude and adjust with live reports from planes ahead, so most flights cross colored areas with little more than a few wobbles.
Can I track turbulence on a flight-tracking app?
Flight trackers show where planes are, not how bumpy the air is. Some turbulence apps overlay forecasts on a map; see our comparison of turbulence apps for what each one actually offers.
