Sunrise and sunset FAQ for Santa Rosa
How accurate are the Santa Rosa sunrise and sunset times?
Times are calculated using NOAA-grade astronomical algorithms based on Santa Rosa's exact coordinates (38.4405, -122.7144) and time zone (America/Los_Angeles). Accuracy is typically within 1 minute. Local horizon obstructions (mountains, tall buildings) can shift the visible sunrise/sunset by a few minutes compared to the calculated value.
How long is the longest day of the year in Santa Rosa?
At Santa Rosa's latitude of 38.44° N, the longest day stretches to about 14h 42m on the June solstice. The shortest day, on the December solstice, is around 9h 18m — a year-round swing of roughly 5h 24m.
When is golden hour in Santa Rosa?
Golden hour in Santa Rosa occurs in the ~60-minute window after sunrise and before sunset, when the sun is low (typically below 6° elevation) and light is softer and warmer. Photographers favour this window for portraits and landscapes. The exact start/end depends on the season — golden hour is shorter near the equinoxes and longer in winter when the sun travels at a shallower angle.
Do Santa Rosa sunrise times change with daylight saving time?
Yes. All times shown here use Santa Rosa's local clock, which switches between standard time and daylight saving time on the dates set by US federal law (second Sunday in March, first Sunday in November). The actual position of the sun does not change — only the clock face does. See our Daylight Saving Time guide for the next change date.
In which direction does the sun rise and set in Santa Rosa?
In Santa Rosa, the sun rises in the east, swinging northeast in summer and southeast in winter, and sets in the west, swinging northwest in summer and southwest in winter. On the equinoxes (around 20 March and 22 September), the sun rises due east and sets due west. Between those dates, the sunrise/sunset points shift along the horizon as Earth's axial tilt changes the sun's declination.
What is solar noon, and when does it happen in Santa Rosa?
Solar noon is the moment the sun is at its highest point in the sky for the day. In Santa Rosa, solar noon arrives roughly 11 minutes after clock noon, because Santa Rosa sits in the central partof its time zone. The exact offset shifts a few minutes through the year due to Earth's elliptical orbit (the "equation of time").
