DJI Agras T70 weather limits for spraying
The DJI Agras T70 is rated for wind up to 22 km/h and 0 to 40 °C. How to plan the spray window around those limits.
The DJI Agras T70 is an agricultural spray drone made by DJI. When you select it in PulveCast, the app loads the limits below and checks every forecast hour against them, together with Delta T, humidity, drift risk and thermal inversion.

Wind: flight limit and spraying window
A maximum wind resistance of 22 km/h (6.1 m/s, 14 mph) means the DJI Agras T70 can hold its position and route in that wind. It is not a recommendation for spraying: the stronger the wind, the more droplets leave the target, especially fine ones. Most labels and extension guides place the useful spraying window well below the flight limit, and dead calm is also a warning sign of a thermal inversion.
How PulveCast rates the wind for the DJI Agras T70
- Green: wind up to 19.8 km/h (90 % of the limit)
- Yellow: from 19.8 to 22 km/h, close to the limit
- Red: above 22 km/h, outside what the drone is rated for
The drift card is scored separately, from the wind speed and the droplet class of your nozzle, so an hour can be green for the aircraft and still yellow or red for drift.
Temperature
The DJI Agras T70 is rated to operate from 0 to 40 °C (32 to 104 °F). Outside that range batteries and electronics are outside their specification. Heat also raises Delta T, so on hot afternoons evaporation usually closes the spray window before the drone limit does.
Other conditions to check
- Delta T between 2 and 8 °C, so droplets neither hang in the air nor evaporate.
- Thermal inversion: common at dawn and dusk on calm, clear days.
- Rain before the product becomes rainfast, as stated on the label.
- Kp index and GNSS satellites for RTK positioning accuracy on the swath.

Frequently asked questions
What is the maximum wind speed for the DJI Agras T70?
The DJI Agras T70 is rated for wind up to 22 km/h (6.1 m/s). That is a flight limit; for spraying, drift usually sets a lower practical limit, so check the product label and the drift risk for your nozzle.
At what temperature can the DJI Agras T70 operate?
From 0 to 40 °C (32 to 104 °F), according to the specification loaded in PulveCast.
What is the best weather to spray with the DJI Agras T70?
Moderate, steady wind well below the drone limit, Delta T between 2 and 8 °C, no thermal inversion and no rain expected before the product is rainfast. PulveCast combines all of these into one verdict per hour.
