Does wind speed affect how a drone flies?
I checked the weather app and it shows 20 mph wind today. Is that too windy to fly my drone or should I be fine? I have a DJI Mini 2 SE. Does wind really matter that much for flight stability and battery life?

Wind has a profound effect on drone flight. At 20 mph (roughly Beaufort 5) most consumer drones can still fly and hold position but will work much harder to do so, draining their batteries 30 to 50 percent faster than in calm conditions. The DJI Mini 2 SE is rated to Beaufort 5 which is approximately 29 to 38 km/h or 18 to 24 mph. At 20 mph you are right at the edge of its rated envelope.
More importantly, the app shows average wind speed but gusts can be significantly higher. If average wind is 20 mph, gusts could hit 30 to 35 mph which exceeds the Mini 2 SE's rating. Fly cautiously, stay close, and be ready to initiate return to home early. Altitude makes a difference too since wind is often stronger 50 to 100 meters up than at ground level where your app measured it.

Wind direction matters just as much as wind speed. A common mistake is flying out into a headwind, which the drone handles fine using more power to push forward. The problem is on the return journey when that same wind becomes a tailwind pushing the drone faster than it expects, making precise positioning and landing much harder.
Plan your flight path so you fly into the wind on the return leg when battery is lower. This ensures the drone is always fighting toward you rather than being pushed past you during landing.

Battery drain in strong wind is not just an inconvenience, it is a safety issue. I have burned through a full battery in under 10 minutes flying into a headwind that would normally give me 28 minutes in calm air. The motors are running at high throttle continuously just to maintain position.
In windy conditions I set a strict 40 percent battery threshold for starting my return rather than the usual 25 percent. This accounts for the increased power demand on the way home. Losing the drone to an empty battery in the middle of a field is an expensive lesson.

The best upgrade for your planning is a proper aviation weather app. UAV Forecast and Windy are both excellent. They show wind speed at altitude, not just ground level, and UAV Forecast gives you a direct green, yellow, or red flying assessment based on your drone model.
Consumer weather apps typically only measure surface wind. Wind at 50 to 100 meters of altitude is commonly 30 to 50 percent stronger. Checking proper aviation wind data before flying has saved me from multiple bad decisions.

Turbulence is often more dangerous than raw wind speed. A consistent steady 20 mph wind is something the drone's flight controller can compensate for once it measures and adjusts. But gusting, unpredictable turbulence behind buildings, trees, or cliff faces changes direction faster than the sensors can react.
Avoid flying in the lee of large obstacles when it is windy because turbulent wakes form in unpredictable ways. Open fields with no nearby structures are much safer in moderate wind than technically calmer spots surrounded by wind-generating obstacles.
