@mhmtozmen Hello, This frost alert would be useful for some types of plants like trees because in Windy, as in most weather apps, the predicted temperature is the temperature at 2 meters height. It is important to note that some crops are more sensitive to frost at ground level (grass temperature). At this level, in some weather conditions, the temperature can be quite lower than the minimum temperature at 2 m. See these related thread https://community.windy.com/topic/26646/frost-predictions?_=1739086900421 https://community.windy.com/topic/19899/alert-for-frost?_=1739086900433 https://community.windy.com/topic/11694/10cm-temperature?_=1739086900440 Unless Windy develop special algorithms, you can already set an Alert for low 2m temperature and clear sky and low wind conditions. Only dew point is missing in the current alert system. Personally I would set 2 or 3 alerts at same location with a different mix of these parameters.
