The weather app built for the grounds crew.
DecideWeather turns the forecast into a clear Go / Caution / Stop recommendation for every agronomic operation — spraying, mowing, topdressing, aerification, irrigation, and tournament setup — built around rainfast intervals, leaf wetness, wind, and soil conditions, tuned to your course.
Timed for the way the course runs.
Spray windows, mowing, topdressing, and tournament prep each answer to different conditions. DecideWeather is built around them — pick your operations and every recommendation is tuned to the thresholds that matter.
Spray applications
Rainfast intervals, leaf wetness, and wind so fungicide and growth-regulator passes hold instead of washing off.
Mowing & rolling
When greens are dry enough to run, read from morning dew and leaf wetness.
Topdressing
Surface moisture and timing so sand works in cleanly.
Aerification
Soil conditions and the recovery window around the operation.
Irrigation
Rainfall and evapotranspiration so you water when it actually counts.
Tournament setup
A seven-day view to sequence prep and setup around the weather.
Other apps report the weather. DecideWeather makes it clear.
A consumer weather app gives you a chance of rain and leaves the agronomy to you. DecideWeather resolves the forecast to your course, checks it against each operation\u2019s thresholds — rainfast, leaf wetness, wind, soil — and shows the window hour by hour, plus real-time alerts and official NWS warnings.
Field notes for superintendents.
Surface temperature vs. air temperature: the number the forecast won't give you
Almost every threshold that decides an outdoor job is a surface threshold — and almost every forecast reports air. Here's how far apart they get, and why the gap is where jobs go wrong.
Cart traffic after rain: reading the ground before you take the ropes down
Cart-path-only is a revenue decision and a turf decision at the same time. Here's how soil saturation and drying rate — not the hours since the rain stopped — should set the call.
Soil temperature and the spring wake-up: the number that starts your season
Turf doesn't respond to the air — it responds to the root zone. Here's why soil temperature, not the forecast high, tells a superintendent when the season has actually started.
What '40% chance of rain' actually means for your crew — and why it isn't what you think
Probability of precipitation is the most misread number in any forecast. Here's what '40% chance of rain' really measures, why it's nearly useless for a job-site call on its own, and what to watch instead when you're scheduling outdoor work.
Weather software for golf courses, answered.
Is there a weather app for golf course superintendents?
Yes. DecideWeather gives grounds crews per-operation work windows for spraying, mowing, topdressing, aerification, irrigation, and tournament setup — based on rainfast intervals, leaf wetness, wind, and soil conditions, tuned to your course.
Can it help time fungicide and spray applications?
Yes. DecideWeather models the spray window from rainfast intervals, leaf wetness, and wind so applications set before the weather turns instead of washing off.
How is it different from a regular weather app?
A consumer weather app tells you the chance of rain. DecideWeather translates the forecast into a Go / Caution / Stop recommendation for each agronomic operation, tuned to your course and the hours your crew works.
Does it work on iPhone and Android?
Yes. DecideWeather is a web app (PWA) you install on your phone’s home screen on iPhone, Android, or desktop, with a 2-week free trial.
