Sunrise & Sunset Times in Sunnyvale — July 2025

Sunrise & Sunset in Sunnyvale During July

July in Sunnyvale still enjoys very long days, though daylight has begun its slow retreat from the June solstice peak. The decrease is gentle at first — just a minute or so per day — so most people barely notice. Sunrise drifts slightly later and sunset slightly earlier, but evenings remain bright and warm. The high sun angle keeps twilight periods long, and the combination of warmth and extended light makes July one of the most daylight-rich months.

Golden Hour & Twilight in July

During July, golden hour in Sunnyvale lasts approximately 64 minutes each morning and evening. The low sun angle during these periods produces warm, directional light prized by photographers and filmmakers. Civil twilight — the period when the sun is just below the horizon — adds extra usable light before sunrise and after sunset, extending the practical daylight window beyond the times shown in the table above.

Through July, days in Sunnyvale are shortening by roughly 1.2 minutes per day, adding up to about 0h 36m over the course of the month.
