Frequently asked
Will the sunset be good tonight in Napa Valley?
The live score above pulls today's forecast and runs it through GoldCast's scoring model. Above 70 is worth going out. Below 40, stay home. The score updates daily.
What makes a good sunset in Napa Valley?
Napa Valley runs north-south between the Mayacamas and Vaca mountain ranges, with the valley floor opening toward the San Pablo Bay to the south. The vineyards and rolling hills catch warm golden light at dusk, and the low ridgelines allow color to build in the western sky without being blocked. The Mayacamas ridge to the west silhouettes gradually as the sun drops behind it. Hot air balloons are common in the early morning but the valley floor and elevated winery sites offer elevated views for evening shooting.
What time is sunset in Napa Valley tonight?
Napa Valley sunset ranges from around 4:50 PM in December to 8:30 PM in June. Tonight's exact time is shown in the score card above, updated daily from live weather data.

What makes a good sunset?

GoldCast scores six atmospheric variables weighted by how much each one actually affects the light. A clear sky isn't always best.

High Cloud
20–80%
Cirrus clouds scatter warm light across the sky. Too little means a bare sky. Too much blocks everything.
Humidity
Under 50%
Low humidity keeps colors vivid and punchy. Above 80% produces milky, washed-out tones.
Horizon Cloud
Clear
Low cloud at the horizon blocks the sun at peak warmth. A small gap makes all the difference.
Post-Storm
Best skies
Rain clears the air and leaves textured cloud at altitude. Often the most dramatic light of the year.
