Seasonal Sun Milestones in National City
National City's 8 PM sunsets run from about June 22 to July 6 — 15 evenings in a typical year. The wider season of sunsets at 7 PM or later lasts 176 days, from March 19 to September 10. At the other end of the year, sunsets before 5 PM begin around November 2 and last until January 7.

The Sun's rising point moves along the horizon too. Around the June solstice it rises in the ENE (61°) and sets in the WNW (299°); by the December solstice it rises in the ESE (118°) and sets in the WSW (242°). That is a 57° swing — worth knowing when choosing a west-facing viewpoint for a summer sunset or an east-facing window for winter morning light.

The Sun's Path Over National City
Where the Sun sits in the sky over National City depends on the season, and the contrast between summer and winter is set by the city's latitude of 32.67°N. On the summer solstice the midday Sun climbs to 80.8° above the horizon in National City — nearly straight overhead, leaving objects almost no shadow at solar noon. On the winter solstice the midday Sun only reaches 33.9°, sitting much lower in the southern sky and casting long shadows even at noon.
Those roughly 47 degrees separating the summer and winter midday Sun are exactly what give National City its seasons.

Earliest and Latest Sunrises and Sunsets in National City
It is natural to assume National City sees its latest sunset on the longest day of the year, but it does not. The latest sunset actually falls around June 29 at about 8:00 PM, while the earliest sunset comes around December 3 at roughly 4:42 PM — noticeably before the December solstice.
On the morning side, the earliest sunrise in National City is around June 11 at 5:40 AM, and the latest sunrise around November 1 at 7:06 AM. The equation of time and daylight saving pull these dates away from the solstices — explained in why the latest sunset isn't on the longest day.
How Daylight Saving Time Moves Sunrise and Sunset in National City
National City, California changes its clocks twice a year, and both changes are visible in this page's numbers. On the second Sunday in March, National City springs forward and the evening changes overnight: sunset jumps from about 5:51 PM on Saturday to about 6:52 PM on Sunday. The price is paid at dawn — sunrise slips from around 6:07 AM back to 7:06 AM, so mornings turn dark again just as they were brightening.
The reverse comes on the first Sunday in November, when clocks fall back: sunset drops from about 5:57 PM to 4:56 PM in a single day — the abrupt start of the early-dusk season — while sunrise brightens from around 7:06 AM to 6:07 AM.
Only the clock label shifts on those Sundays; the times above are for a typical year. More in how daylight saving time changes sunrise and sunset.
Golden Hour & Blue Hour Photography in National City
For photographers in National City, California, the planner shows your selected date's morning and evening golden-hour and blue-hour windows. Choose Today, Tomorrow, or a date in the calendar; all clock times are calculated in National City's local timezone.
Golden "hour" is a misnomer — its length in National City depends on the season, because it lasts as long as the Sun takes to climb from the horizon to 6° (or descend back). Around the equinoxes it runs about 33 minutes; near the June solstice, when the Sun rises and sets at a shallower angle, it stretches to roughly 36 minutes, and near the December solstice it lasts about 38 minutes.
See the golden hour guide and blue hour guide for how to plan a shoot around these windows.
Solar Energy Potential in National City
Under clear skies, National City, California receives about 5.7 peak sun hours per day averaged across the year — from roughly 2.8 in December up to 8.3 in June. One peak sun hour equals one hour of sunlight at full intensity (1 kW/m²), the standard unit for estimating solar panel output.
Because National City sits at 32.7°N, a fixed, south-facing panel captures the most energy over the year when tilted at roughly 33° from horizontal — about equal to the latitude. If you adjust the tilt seasonally, flatten to about 18° in summer, when the Sun rides high, and steepen to about 48° in winter, when it stays low.
These are clear-sky upper bounds from National City's solar geometry, not a forecast; clouds, shading, and equipment lower real output. See what peak sun hours mean.
How National City Compares
Daylight in National City swings 4h 18m between the June and December solstices. The median across the 1,847 cities on this site is 5h 16m, so National City has a 58m gentler seasonal swing than a typical American city. By that measure National City ranks 1503rd of 1,847 nationally, and 305th of the 307 California cities listed here — counting from the largest swing down.
National City sits about 2.9° east of 120°W — the meridian Pacific Time is built around. Longitude alone therefore puts mean solar noon roughly 12 minutes before clock noon in standard time, so the Sun runs ahead of the clock here. The equation of time then moves true solar noon up to about 16 minutes either side of that through the year.
