Short answer: most consumer drones are rated to operate up to 40 °C (104 °F), and their batteries charge only between 5 °C and 40 °C. Even below 40 °C, heat costs you: the battery runs hotter, hot air gives the propellers less to push against, and your phone may shut down before the drone does. Fly early or late, keep everything out of direct sun and land with a bigger reserve.

Check the rated maximum first

75 of the 77 models on our drone wind and temperature limits chart top out at 40 °C. The exceptions are the enterprise DJI Matrice 30 and 30T, rated to 50 °C.

Model	Operating temperature	Battery charging temperature
DJI Neo	−10 to 40 °C	5 to 40 °C
DJI Mini 4 Pro	−10 to 40 °C	5 to 40 °C
DJI Mini 5 Pro	−10 to 40 °C	5 to 40 °C
DJI Avata 2	−10 to 40 °C	5 to 40 °C
DJI Air 3S	−10 to 40 °C	5 to 40 °C
DJI Mavic 4 Pro	−10 to 40 °C	5 to 40 °C
DJI Matrice 30 (enterprise)	−20 to 50 °C	−20 to 40 °C

Treat the maximum as a ceiling, not a comfortable flying temperature.

The forecast is a shade temperature

Forecast temperatures are air temperatures, measured about 1.25 m above the ground in a screen "designed to shield instruments from direct sunlight" (Met Office). A drone, battery or phone in full sun can get hotter than the forecast number.

What heat does to the battery

The DJI Mini 4 Pro manual spells out the limits:

The battery only charges between 5 and 40 °C, and charging stops automatically if the cells go above 55 °C.
"DO NOT charge an Intelligent Flight Battery immediately after flight as it may be too hot." Let it cool to the operating temperature first.
Store batteries "in a cool, dry place away from direct sunlight" and never outside −10 to 45 °C.

Keep spare batteries in the shade and out of a car parked in the sun.

Do not leave the drone idling in the sun

The Mini 4 Pro has no fan: it "uses the wind generated by the propellers to dissipate heat during the flight". In standby on the ground "its temperature may continuously rise"; the drone switches to an energy-saving mode without flight functions and, if it keeps heating up, "it will power off to prevent overheating". Check your own model's manual, but:

Set up in the shade and power on just before take-off.
Do not leave it recording on hot ground between flights.
Never block the camera's ventilation holes; DJI warns the trapped heat "may damage the device".

Hot air gives less lift

A drone flies by pushing air down, and thin air gives it less to push. The FAA's Pilot's Handbook of Aeronautical Knowledge lists what less dense air reduces, including "Thrust, because the propeller is less efficient in thin air", and names the conditions that make air thin: "high elevations, low atmospheric pressures, high temperatures, high humidity, or some combination of these factors".

Heat: at the same pressure, air at 40 °C is about 8 % less dense than at the standard 15 °C (our gas-law calculation).
Humidity: moist air is lighter than dry air; the FAA calls it a smaller factor that "does contribute".
Elevation: pressure, and with it density, drops as you climb. DJI says the "performance of the aircraft and its battery is limited when flying at high altitudes" and caps the Mini 4 Pro's take-off altitude at 4,000 m (1,500 m with propeller guards).

In thin air the motors work harder to hold the same hover, which drains the battery faster and leaves less power for climbing or fighting the wind. A hot afternoon at a mountain viewpoint stacks all three effects: keep a wider margin to your drone's wind limit.

Your phone may quit first

Apple designs iPhone "for use where the ambient temperature is between 0º and 35º C", lower than the drone's 40 °C, and lists direct sunlight as a cause of overheating. A hot phone shows a warning, "the display dims or goes black" and charging slows or stops. DJI's instruction: "If the mobile device turns off for any reason, land the aircraft as soon as possible." A sun hood and a phone kept in the shade until take-off help.

A hot-weather routine

Fly in the cooler hours, early or late.
Keep the drone, batteries and phone in the shade until you fly.
Plan shorter flights and land with a larger reserve.
Land if the drone's app (DJI Fly or similar) shows a temperature warning.
Let each battery cool down before charging it.

How Drone Weather Forecast checks it

Each drone preset carries the manufacturer's operating temperature range. For every forecast hour the app compares the forecast temperature with your drone's range and colours it yellow near the limit and red outside it, so a 39 °C afternoon stands out before you leave home. In full sun, plan as if it were hotter.
