A Sponsored Feature

Each day lists the local time, hh:mm in 24h time, that is the starting hour of a past clear sky chart. Each clear sky chart forecasts a few days into the future. There are at least two clear sky chart updates per day. So there are multiple overlapping forecasts for each day.

Instead of the last few past clear sky chart images, some people prefer long-term averages of forecasts. See the Forecast History/Climate page.
