How GoodDayTo judges mowing weather
Mowing is one of those jobs where the weather can waste your time. A dry-looking hour is not very useful if rain is about to arrive, while high humidity can leave grass damp even after precipitation stops. GoodDayTo therefore looks at the next few hours together and gives more weight to low rain risk, drier air, comfortable temperatures and manageable wind.
- Rain probability
- Forecast precipitation
- Relative humidity
- Apparent temperature
- Wind
- Severe weather codes
🌱 A good score means “weather looks worth mowing in”
- If the score says WAIT, a later dry window may be much better than starting on damp grass.
- High humidity can slow drying even when it is not actively raining.
- Strong wind can make clippings, dust and general comfort worse.
Why dry grass matters
Wet grass can clump, stick to the mower deck and leave an uneven finish. It can also be more slippery underfoot, especially on slopes. GoodDayTo cannot touch the lawn, so it does not claim to know the actual blade or soil moisture. Instead, it uses forecast precipitation and humidity as indicators of whether conditions are likely to be favourable.
A GO result is most useful when the lawn already looks and feels dry. If it rained heavily overnight, the forecast may improve before the ground itself has recovered. In that case, local observation should override the score.
What the mowing score cannot know
The app does not know your grass type, grass height, soil drainage, mower type, slope, local noise rules or whether the lawn is shaded. It also cannot tell whether the ground is soft enough for wheels to leave ruts. Use GoodDayTo as the weather layer, then make the final call from the condition of the lawn in front of you.
For very long or stressed grass, weather is only one part of a good mowing decision. Cutting too much at once or mowing during drought stress can affect lawn health even on a beautiful day.
What the score means
GO means the measured weather looks favourable for mowing. WAIT means conditions are mixed or a better dry period is likely later. NOT TODAY means rain, dampness, temperature or a severe-weather signal makes mowing a poor weather choice right now.
Frequently asked questions
Why can a dry forecast still be poor for mowing?
The grass may still be wet from earlier rain or dew even when no new rain is falling. GoodDayTo uses the forecast and humidity, but it cannot directly measure how wet your lawn is.
Does wind affect the lawn-mowing score?
Yes. Strong wind can make mowing less comfortable and can blow clippings and debris around, so higher wind reduces the recommendation.
Why does GoodDayTo avoid late-evening mowing windows?
Mowing is normally a daylight task and can create neighbourhood noise. The scoring therefore favours morning and afternoon rather than treating a calm late night as a good mowing opportunity.
Does a GO result mean the ground is firm enough for a mower?
No. Soil saturation, standing water, slopes and lawn condition are not measured. Check the ground before using a mower, especially after recent rain.
How far ahead does the mowing score look?
It compares the upcoming hourly forecast and searches for a practical multi-hour window, rather than judging the activity from the weather at one instant.
