Chula Vista daylight month by month

Sunrise, sunset, and total daylight for the first of each month in 2026, computed from Chula Vista’s coordinates in local time. The line traces how the day stretches toward summer and contracts toward winter.

Chula Vista’s longest and shortest days

Chula Vista’s longest day falls on June 21, 2026 with 14h 18m of daylight; the shortest is December 21, 2026 with just 10h 0m. The two equinoxes, when day and night run nearly equal, sit in between.

How fast Chula Vista gains and loses daylight

The pace of change is not steady. Each month gains or loses a different amount, fastest around the equinoxes and nearly frozen at the solstices. The rate below is the daily change mid-month; the net is the full swing across the month.

Chula Vista golden hour & blue hour by season

Golden hour is the warm, low-sun light; blue hour is the cooler twilight that brackets it. These windows come from Chula Vista’s true solar geometry — the sun’s altitude, not a fixed hour — so they stretch toward the solstices and run longer than the rule-of-thumb hour.

Daylight saving time in Chula Vista

Chula Vista springs its clocks forward on Sunday, March 8, 2026 and falls back on Sunday, November 1, 2026. Between those dates the local clock runs an hour later, so sunrise and sunset both read later — though the amount of daylight is unchanged; only the label on the clock moves.

Why sunset time shifts in Chula Vista

Sunset drifts through the year with Earth’s ~23.4° axial tilt — see the full daylight explainer.

In Chula Vista, the longest day carries about 14h 18m of daylight and the shortest just 10h 0m — a swing of roughly 4h 18m between the June and December solstices. The farther a place sits from the equator, the wider that gap; the pace also isn’t steady, moving fastest near the equinoxes and barely at all near the solstices. Every figure here is computed from the sun’s position for Chula Vista’s exact coordinates, in local time.
