Sunrise & Sunset in Yuma Today
The live calculator above computes sunrise, sunset, solar noon, day length, golden hour, and each twilight boundary for the current calendar date in Yuma, 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 Yuma
At 32.60°N, Yuma has a milder seasonal daylight swing than cities to the north. Across the year, the length of the day here varies by 4h 17m.
On the summer solstice around June 21, Yuma receives 14h 18m of daylight — the longest day of the year. By the winter solstice around December 21, that shrinks to 10h 0m, 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 Yuma 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 Yuma 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 Yuma
Where the Sun sits in the sky over Yuma depends on the season, and the contrast between summer and winter is set by the city's latitude of 32.60°N. On the summer solstice the midday Sun climbs to 80.8° above the horizon in Yuma — nearly straight overhead, leaving objects almost no shadow at solar noon. On the winter solstice the midday Sun only reaches 34.0°, 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 Yuma 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 Yuma
It is natural to assume Yuma 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 7:50 PM, while the earliest sunset comes around December 3 at roughly 5:32 PM — noticeably before the December solstice.
On the morning side, the earliest sunrise in Yuma is around June 11 at 5:30 AM, and the latest sunrise around January 8 at 7:41 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 Yuma 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 Yuma
Unlike most of the United States, Yuma, 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 Yuma only ranges from about 5:32 PM at the earliest to 7:50 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 Yuma 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 Yuma
For photographers in Yuma, 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 Yuma's local timezone.
Golden "hour" is a misnomer — its length in Yuma 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 32 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.
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 Yuma: the air is usually calmer and clearer than at sunset, and locations are emptier.
Solar Energy Potential in Yuma
Under clear skies, Yuma, Arizona 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 Yuma sits at 32.6°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 theoretical clear-sky values computed from Yuma'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 Yuma Compares
Daylight in Yuma swings 4h 17m between the June and December solstices. The median across the 1,847 cities on this site is 5h 16m, so Yuma has a 59m gentler seasonal swing than a typical American city. By that measure Yuma ranks 1509th of 1,847 nationally, and 29th of the 38 Arizona cities listed here — counting from the largest swing down.
Yuma sits about 9.5° west of 105°W — the meridian Mountain Time (no daylight saving) is built around. Longitude alone therefore puts mean solar noon roughly 38 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 Yuma
Yuma, Arizona, has an estimated urban-area population of 145,839. Its primary county or equivalent is Yuma; its center is at 32.60°N, 114.55°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 Yuma'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 Yuma area.
