How to read this forecast
Most forecasts give each hour one symbol. In broken cloud that hides a lot: an hour with twenty minutes of direct sun is still drawn as a cloud. This page uses a sun score from 0 to 100 for every daylight hour instead. It combines how many minutes of direct sunshine the weather model expects in that hour with how much of the sky is covered by cloud. A sunny hour here is one that scores above 66.
The best window is the one or two hours in a row with the most sun, marked down for rain risk and strong wind. Evening golden hour is the stretch around sunset when the light is low and warm, which photographers like.
This page says when the sun will be out, not how strong it is. For that, see the UV index in Portsmouth.
