It's a hot day — a hat, sunglasses, and plenty of water are a must.
An average day — best chances during peak windows.

These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +100°
The day is 2 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.
