PulveCast: Spray Weather

Spray now or wait? PulveCast answers with one colour for every hour — green, yellow or red — checked against the limits of your own equipment, crop and nozzle. Built for agricultural spray drones, tractor boom sprayers and self-propelled sprayers. Before you fill the tank, see if the weather window is safe and efficient, and which parameter closes it. WHAT PULVECAST CHECKS, HOUR BY HOUR • Delta T — the best single indicator of droplet evaporation (ideal 2–8 °C by default) • Relative humidity and dew point • Spray drift risk — wind speed crossed with your nozzle's droplet class, Very Fine to Ultra Coarse • Thermal inversion — forecast temperature at 80 m against 10 m, the classic dawn hazard • Wind speed, gusts and direction against your equipment's ceiling • Temperature, rain probability, cloud cover and visibility • For drones: Kp index and visible GPS, GLONASS, Galileo and BeiDou satellites for RTK accuracy FREE, NO ADS, NO ACCOUNT • Spray verdict for the day, with the reason for every yellow or red hour • Best spray windows of the day, and the forecast shared as an image on WhatsApp • Delta T, humidity, dew point, drift, inversion, wind and gusts • Equipment settings: spray drone, tractor or self-propelled sprayer • Presets for 18 agricultural drone models from DJI Agras, XAG, Hylio and TTA, with their wind and temperature limits • Pre-operation checklists • km/h, m/s, mph or knots · °C or °F · metres or feet • Last forecast kept offline for the far end of the farm • 16 languages PULVECAST PRO • Multi-day planning and the full hourly forecast table • Wind compass • Best spray windows for 7 days, with a phone alert before each one • Several drones, each with its own flight limits • Operation planner, application log with spreadsheet export, and sensitive sides of each saved field (homes, apiaries, water) marked on its map, with a warning and a phone notification when the drift heads there • Spray calculator: droplet class against wind • Crop presets for soybean, corn, sugarcane, cotton, wheat, coffee, beans, rice, sorghum, peanut, potato, tomato, citrus, grape, banana, eucalyptus and pasture, or your own thresholds for any crop • No-fly zone map with official zones and height limits (plus DJI zones), 24-hour Delta T and humidity history, favourite locations • Premium forecast sources: WeatherAPI and Apple WeatherKit Every threshold can be changed to match your own operating standard.
