Frequently asked questions
How do I know if it's safe to spray today?
Check live wind, gusts, rain chance, humidity, and temperature for your exact location. As a rule of thumb, spray in a steady 3–10 mph breeze, avoid sustained wind at or above 15 mph or gusts at or above 20 mph, skip it when rain is likely within four hours, and stop when temperatures reach 90°F. This tool combines all of those into a single Good / Marginal / Do Not Spray verdict.
What wind speed is too high for spraying?
Most labels and applicators treat sustained wind at or above 15 mph, or gusts at or above 20 mph, as too windy because fine droplets drift off-target. Wind from about 3 to 10 mph is ideal. Dead-calm air below roughly 2 mph can also be risky when a temperature inversion traps the spray near the ground.
Why does soil temperature matter for spraying?
Many lawn-care products are timed to soil temperature rather than air temperature — pre-emergents, for example, should go down before the 2-inch soil holds 55°F. The tool shows the current 2-inch soil-temperature reading so you can line up soil-driven applications with the right window.
Is this spray-conditions checker free?
Yes. The verdict, current conditions, hourly spray windows, and soil temperature are all free with no signup. You can optionally enter your email to get this week's spray windows sent to you, but it's never required to see the live results.
