Spray, harvest and irrigate in the right window

Farm work runs on narrow weather windows. weatherAI.io finds them for spraying (drift and wash-off), harvesting and haymaking (dry crop, low humidity) and irrigation (low wind, no rain on the way), and can alert you when a window opens.

Activities in this pack

Crop spraying

activity=crop-spraying · windows of 2 h or more

Spraying crops: a light, steady breeze (about 3 to 15 km/h; dead calm risks drift in an inversion), no rain soon after, not hot. Always follow the product label.

Harvesting and haymaking

activity=harvesting · windows of 5 h or more

Combining, baling and haymaking: a dry crop and dry ground. No rain, low humidity (dew and damp grain), a breeze helps; storms stop work.

Irrigation and watering

activity=irrigation · windows of 2 h or more

Irrigating crops, lawns and sports pitches: little wind (drift), no rain on the way (wasted water), and cool hours with weak sun (less evaporation). No watering near freezing.

Drone flying

activity=drone-flying · windows of 1 h or more

Short flights in daylight: low wind and gusts, no rain or snow, good visibility, batteries above about 5°C. Always follow local drone rules.

Outdoor work (building sites, landscaping, events crew)

activity=outdoor-work · windows of 4 h or more

A shift outdoors: heat stress first, then storms, cold, ice and heavy rain.
