Do not stop at the weather icon
A sun-and-cloud symbol can hide a day that changes significantly between morning and afternoon. Check at least rain probability over the next hours, wind and gusts, thunderstorm risk and radar evolution.
Rain probability
A 40% probability does not mean it will rain for 40% of the day. For planning, the hour-by-hour trend is more useful than a single daily number.
Wind and gusts
For activities on the lake, gusts can matter more than average wind. Moderate mean wind with strong gusts may still be demanding for small boats, SUPs and exposed activities.
Combine forecast and observation
The forecast describes a likely scenario; radar shows observed precipitation. Use the forecast for planning and radar to verify the immediate evolution before leaving.
