Seasonal Sun Milestones in Williston
Williston's 9 PM sunsets run from about April 25 to August 19 — 117 evenings in a typical year. The wider season of sunsets at 7 PM or later lasts 223 days, from March 9 to October 17. Even in midwinter, sunset here never falls before 5 PM on the clock.
Days in Williston first reach 12 hours of daylight around March 17, a few days before the March equinox, and drop back under 12 hours after September 24. Days with at least 15 hours of daylight run from May 11 to July 31. Days with less than 9 hours of daylight run from November 21 to January 19 (60 days).
The Sun's rising point moves along the horizon too. Around the June solstice it rises in the NE (52°) and sets in the NW (308°); by the December solstice it rises in the SE (125°) and sets in the SW (235°). That is a 73° swing — worth knowing when choosing a west-facing viewpoint for a summer sunset or an east-facing window for winter morning light.
Dates use the 2025 reference year. Clock-time milestones near daylight-saving changes move with the second Sunday in March and the first Sunday in November.

The Sun's Path Over Williston
Where the Sun sits in the sky over Williston depends on the season, and the contrast between summer and winter is set by the city's latitude of 48.18°N. On the summer solstice the midday Sun reaches 65.3° above the horizon in Williston, its highest point of the year. On the winter solstice the midday Sun only reaches 18.4°, 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 Williston its seasons.

Earliest and Latest Sunrises and Sunsets in Williston
It is natural to assume Williston sees its latest sunset on the longest day of the year, but it does not. The latest sunset actually falls around June 25 at about 9:59 PM, while the earliest sunset comes around December 11 at roughly 5:01 PM — noticeably before the December solstice.
On the morning side, the earliest sunrise in Williston is around June 16 at 5:54 AM, and the latest sunrise around December 31 at 8:45 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 Williston
Williston, North Dakota changes its clocks twice a year, and both changes are visible in this page's numbers. On the second Sunday in March, Williston springs forward and the evening changes overnight: sunset jumps from about 6:50 PM on Saturday to about 7:52 PM on Sunday. The price is paid at dawn — sunrise slips from around 7:21 AM back to 8:19 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 6:35 PM to 5:33 PM in a single day — the abrupt start of the early-dusk season — while sunrise brightens from around 8:41 AM to 7:42 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 Williston
For photographers in Williston, North Dakota, 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 Williston's local timezone.
Golden "hour" is a misnomer — its length in Williston 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 41 minutes; near the June solstice, when the Sun rises and sets at a shallower angle, it stretches to roughly 49 minutes, and near the December solstice it lasts about 54 minutes.
See the golden hour guide and blue hour guide for how to plan a shoot around these windows.
Solar Energy Potential in Williston
Under clear skies, Williston, North Dakota receives about 4.4 peak sun hours per day averaged across the year — from roughly 1 in December up to 8.1 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 Williston sits at 48.2°N, a fixed, south-facing panel captures the most energy over the year when tilted at roughly 48° from horizontal — about equal to the latitude. If you adjust the tilt seasonally, flatten to about 33° in summer, when the Sun rides high, and steepen to about 63° in winter, when it stays low.
These are clear-sky upper bounds from Williston's solar geometry, not a forecast; clouds, shading, and equipment lower real output. See what peak sun hours mean.
How Williston Compares
Daylight in Williston swings 7h 44m between the June and December solstices. The median across the 1,847 cities on this site is 5h 16m, so the seasons move the clock 2h 28m further in Williston than in a typical American city. By that measure Williston ranks 8th of 1,847 nationally, and 2nd of the 7 North Dakota cities listed here — counting from the largest swing down.
Williston sits about 13.6° west of 90°W — the meridian Central Time is built around. Longitude alone therefore puts mean solar noon roughly 55 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. The equation of time then moves true solar noon up to about 16 minutes either side of that through the year.
