What does Sol show for sunset?

A colour forecast from little colour to exceptional colour, with sunset time, viewing direction and the conditions behind the outlook.

How does Sol assess sunset conditions?

Sol checks forecast cloud overhead and at 120, 250 and 400 km along the sunset bearing to estimate whether sunlight can reach cloud near you.

What if the forecast is unavailable?

Sol still calculates sunset time, viewing direction and golden hour. Colour forecasts are estimates, and conditions can change.

What to expect tonight

The call weighs the cloud over you — some lights a sunset, none or all does not — against the cloud along the light's path from the west, where low cloud far out blocks it. One of four words: tendencies, not promises.
