Autel EVO II 8K wind limit
Autel’s rated wind resistance, recommended limits in every unit, and what a ground forecast means at 120 m.
Autel rates the EVO II 8K for winds up to 12.0 m/s (27 mph, 43 km/h, Level 6). A steady 20 mph (8.9 m/s) at flight height is 75% of that rating, which our score calls Marginal. For a comfortable margin keep sustained wind at altitude under 7.2 m/s (16 mph) and estimated gusts under 9.6 m/s (21 mph).
Wind limits in every unit
Our default go/no-go thresholds are a share of the maker’s rating: sustained wind up to 60% is within your limits, up to 85% is marginal; estimated gusts up to 80% are within, up to 100% marginal.
| m/s | km/h | mph | knots | Beaufort | |
|---|---|---|---|---|---|
| Autel’s max wind rating | 12.0 | 43 | 27 | 23 | 6 |
| Sustained wind: within your limits up to (60%) | 7.2 | 26 | 16 | 14 | 4 |
| Sustained wind: marginal up to (85%) | 10.2 | 37 | 23 | 20 | 5 |
| Estimated gusts: within your limits up to (80%) | 9.6 | 35 | 21 | 19 | 5 |
| Estimated gusts: marginal up to (100%) | 12.0 | 43 | 27 | 23 | 6 |
What a ground forecast means at 120 m
Most forecasts give wind at 10 m. Higher up it is stronger. With the standard power law (α = 0.14 over open land by day, about 0.25 at night or over towns and forest), here is the sustained wind the EVO II 8K meets at 120 m (400 ft), and how our score rates it. Altiwind uses the model’s own 80, 120 and 180 m winds where they exist.
| Wind at 10 m | 120 m, open land by day | Score | 120 m, night or urban | Score |
|---|---|---|---|---|
| 10 km/h (6 mph) | 14 km/h | Within your limits | 19 km/h | Within your limits |
| 15 km/h (9 mph) | 21 km/h | Within your limits | 28 km/h | Marginal |
| 20 km/h (12 mph) | 28 km/h | Marginal | 37 km/h | Outside your limits |
| 25 km/h (16 mph) | 35 km/h | Marginal | 47 km/h | Outside your limits |
| 30 km/h (19 mph) | 42 km/h | Outside your limits | 56 km/h | Outside your limits |
| 35 km/h (22 mph) | 50 km/h | Outside your limits | 65 km/h | Outside your limits |
| 40 km/h (25 mph) | 57 km/h | Outside your limits | 74 km/h | Outside your limits |
Sustained wind only. Gusts come on top: Altiwind adds the forecast 10 m gust excess (gust minus mean, never less than 20% of the wind), so check the estimated gusts too. See wind at altitude and gust forecast. UAV Forecast also shows wind by height: how it compares with Altiwind.
Cold weather
Autel rates the EVO II 8K down to -10 °C. Batteries lose capacity in the cold well before that, so Altiwind marks every hour below 5 °C as marginal with a battery warning, and below -10 °C as outside your limits. More in flying drones in cold weather.
Rain and moisture
There is no water rating stated for the EVO II 8K, so Altiwind treats rain as a limit: a rain chance of 20% or more is marginal and 50% or more is outside your limits. Fog and low cloud also cut visibility, which the score checks separately. See fog, rain and humidity.

Autel's current 'EVO II' page (8K, 48MP) gives 12 m/s as the takeoff/landing limit. Autel's 2020 store spec page (auteldrones.com, archived) said 1150 g, 'Force 8 wind' and 0–40 °C; this entry uses the current values. Launched at CES 2020.
FAQ
Can the Autel EVO II 8K fly in 20 mph wind?
20 mph is 8.9 m/s, 75% of the 12.0 m/s rating from Autel. Altiwind scores that as marginal for sustained wind at flight height. Gusts and the stronger wind higher up matter too.
What is the Autel EVO II 8K’s wind resistance level?
12.0 m/s (43 km/h, 27 mph), which is Level 6 on the Beaufort scale. That is the most the drone is designed to handle, not a comfortable working wind.
Can the Autel EVO II 8K fly in cold weather?
Autel rates the EVO II 8K down to -10 °C. Batteries lose capacity in the cold well before that, so Altiwind marks every hour below 5 °C as marginal with a battery warning, and below -10 °C as outside your limits.
Is the Autel EVO II 8K waterproof?
Autel doesn’t state a water rating for it, so treat rain and wet fog as outside your limits.
