How to read it
What makes a day workable
- Delta T 2–8The gap between dry and wet bulb temperature. Below 2 the air is close to saturated, which brings inversion risk and drift that hangs about instead of settling. Above 8 droplets evaporate before they reach the target and you have paid for chemical that never landed. 2–6 is the sweet spot.
- Wind 2–10 mphAbove 10 mph you are outside most product labels for ground application. Below 2 mph sounds ideal but usually is not — still air often means an inversion, and the spray goes where it likes. 3–7 mph with a steady direction is what you want.
- Gusts under 15 mphA steady 7 mph is workable. The same average with 15+ mph gusts through it is not, because the boom never settles.
- No rain in the hourRain in the hour rules it out. A high chance of rain drops the hour to marginal — rainfastness varies by product, so check the label before you rely on a gap.
What this is not
This is a forecast, not a recommendation. It uses public weather data for a point near the town, not a reading from your field, and it knows nothing about the product you are applying, the crop stage, buffer zones or your LERAP obligations.
Every application is the operator’s decision on the day, against the product label. We publish this because it is the honest version of what we look at ourselves — not as something to point at afterwards.
Where the numbers come from
Data and method
- Forecast
- Open-Meteo, hourly, for the coordinates of each town in the list. Fetched by your browser when you open the page, so it is never older than the page in front of you.
- Delta T
- Calculated from forecast temperature and relative humidity using Stull’s wet bulb approximation, accurate to roughly ±0.3°C in the range that matters here.
- Verdict
- A day is marked good when it holds at least three good hours between 5am and 9pm, marginal when it holds three workable ones, and poor otherwise.

Window looks tight?
We plan around these numbers every day. If you cannot get on it yourself, tell us the acreage and where you are, and we will tell you honestly whether we can reach you in time.
