Sunrise & Sunset in Sun City Today
The live calculator above computes sunrise, sunset, solar noon, day length, golden hour, and each twilight boundary for the current calendar date in Sun City, Arizona. It runs in your browser from the city-center coordinates and the America/Phoenix timezone, so the answer stays current even though this page is a permanent static file.
Times are rounded to the nearest minute. They model a standard, unobstructed horizon; mountains, buildings, elevation, weather, and unusual atmospheric refraction can move the sunrise or sunset you actually observe by a few minutes.
Daylight Through the Year in Sun City
At 33.62°N, Sun City has a milder seasonal daylight swing than cities to the north. Across the year, the length of the day here varies by 4h 28m.
On the summer solstice around June 21, Sun City receives 14h 23m of daylight — the longest day of the year. By the winter solstice around December 21, that shrinks to 9h 55m, the shortest day. At the spring and autumn equinoxes, day and night are nearly equal at about 12h 9m, as they are everywhere on Earth.
The reason is the Earth's axial tilt of roughly 23.44 degrees. In summer the Northern Hemisphere leans toward the Sun, so Sun City sees the Sun climb high and trace a long arc across the sky. In winter the hemisphere leans away, the Sun stays low, and the days are short. The change is fastest near the equinoxes — in Sun City the sunset can shift by two to three minutes per day in March and September — and slowest near the solstices, when it barely moves for weeks.
The Sun's Path Over Sun City
Where the Sun sits in the sky over Sun City depends on the season, and the contrast between summer and winter is set by the city's latitude of 33.62°N. On the summer solstice the midday Sun reaches 79.8° above the horizon in Sun City, its highest point of the year. On the winter solstice the midday Sun only reaches 33.0°, 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 Sun City its seasons. A high summer Sun delivers its energy almost straight down, warming the ground efficiently and producing intense midday light. A low winter Sun spreads the same energy across a wider area and filters it through more atmosphere, which is why winters are cooler and the light feels softer and warmer in tone.
Through the day the Sun rises in the east, swings through the southern sky, and sets in the west. Around the summer solstice it rises and sets well to the north of due east and west; around the winter solstice it rises and sets to the south. The exact bearing for any moment — along with the Sun's current altitude and ESE-to-WSW arc — is shown live in the tracker at the top of this page.
Earliest and Latest Sunrises and Sunsets in Sun City
It is natural to assume Sun 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 7:43 PM, while the earliest sunset comes around December 4 at roughly 5:21 PM — noticeably before the December solstice.
On the morning side, the earliest sunrise in Sun City is around June 12 at 5:18 AM, and the latest sunrise around January 7 at 7:34 AM. These dates drift away from the solstices because of two effects working together: the equation of time, which comes from the Earth's tilt and its slightly elliptical orbit, and the clock shift of daylight saving time. The result is that solar noon itself wanders earlier and later by up to about 16 minutes over the year, pulling the sunrise and sunset extremes onto dates that surprise most people.
Below the Sun's path, twilight extends the usable light at each end of the day. Civil twilight (Sun 0–6° below the horizon) keeps Sun City bright enough for most outdoor activity; nautical twilight (6–12°) is when the brighter stars and the sea horizon are both visible; and astronomical twilight (12–18°) is the final fade to true darkness. The live calculator above lists today's calculated boundaries for all three.
No Clock Changes in Sun City
Unlike most of the United States, Sun City, Arizona does not observe daylight saving time. Most of Arizona has kept standard time year-round since the late 1960s — the summer evenings are hot enough that an extra hour of evening sun was never popular. (The Navajo Nation, in the state's northeast, is the exception and does change its clocks.)
In practice this means no jarring one-hour jump in sunrise and sunset twice a year. Across the whole year, sunset in Sun City only ranges from about 5:21 PM at the earliest to 7:43 PM at the latest — the change residents notice is gradual and driven purely by the Sun, never by the clock.
One side effect worth knowing: the time difference between Sun City and cities that do change their clocks shifts twice a year. A place that is normally in the same hour can be an hour off from mid-March to early November, which matters for calls, broadcasts, and travel schedules.
Golden Hour & Blue Hour Photography in Sun City
For photographers in Sun City, Arizona, 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 Sun City's local timezone.
Golden "hour" is a misnomer — its length in Sun 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 37 minutes, and near the December solstice it lasts about 38 minutes.
Golden hour gives warm tones, long soft shadows, and directional light that flatters landscapes and portraits alike. Blue hour — when the Sun sits 4–6° below the horizon — delivers an even, cool-toned sky that balances beautifully against artificial lights, which is why it's the classic window for cityscape and architecture shots. Sunrise sessions have a practical edge in Sun City: the air is usually calmer and clearer than at sunset, and locations are emptier.
Solar Energy Potential in Sun City
Under clear skies, Sun City, Arizona receives about 5.6 peak sun hours per day averaged across the year — from roughly 2.7 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 Sun City sits at 33.6°N, a fixed, south-facing panel captures the most energy over the year when tilted at roughly 34° from horizontal — about equal to the latitude. If you adjust the tilt seasonally, flatten to about 19° in summer, when the Sun rides high, and steepen to about 49° in winter, when it stays low.
These are theoretical clear-sky values computed from Sun City's solar geometry — they show the shape of the year and the ceiling on production, not a forecast. Actual output depends on local cloud cover, temperature, shading, and equipment, so treat the figures as an upper bound and the month-to-month pattern as the reliable part. The seasonal swing is real and unavoidable: in December the Sun is above the horizon for fewer hours and sits lower in the sky, spreading its energy across more atmosphere and more ground.
How Sun City Compares
Daylight in Sun City swings 4h 28m between the June and December solstices. The median across the 1,847 cities on this site is 5h 16m, so Sun City has a 48m gentler seasonal swing than a typical American city. By that measure Sun City ranks 1382nd of 1,847 nationally, and 11th of the 38 Arizona cities listed here — counting from the largest swing down.
Sun City sits about 7.3° west of 105°W — the meridian Mountain Time (no daylight saving) is built around. Longitude alone therefore puts mean solar noon roughly 29 minutes after clock noon in standard time, so the Sun runs behind the clock here, which is why evenings hold light later than the time zone would suggest. This offset is fixed by geography, but it is not the whole story: the equation of time moves true solar noon up to about 16 minutes either side of the mean across the year, which is why the solar-noon figure at the top of this page drifts from month to month.
About Sun Times in Sun City
Sun City, Arizona, has an estimated urban-area population of 37,486. Its primary county or equivalent is Maricopa; its center is at 33.62°N, 112.28°W. Clocks here follow Mountain Time (no daylight saving), which is the timezone all sunrise, sunset, golden-hour and twilight times on this page are shown in.
Because these times are computed from Sun City's city-center coordinates rather than a regional average, they can differ by a few minutes from a neighboring town to the east or west — the Sun reaches places farther east first. For planning away from the city center, compare the nearby-city pages and allow for the local terrain and horizon in the Maricopa area.
