Sunrise and sunset in the most important cities of Cambodia

The cities are ordered by their geographic position from east to west, so in an approximate direction of the sun's course. Since the orbit around the sun is elliptical, sunrise or sunset never happen on a whole longitude at the same time. All data given for January 25th., localtime in Cambodia

Duration of the sunset

The distance from the equator and the path of the sun determines not only the time of sunrise and sunset. The farther a country is from the equator, the more oblique the sun's path is to the horizon, causing sunset to last for a different duration. Phnom Penh lies on the 12th degree of northern latitude and thus a good distance from the equator. While a sunset in the northern USA or central Europe can take almost an hour, in Cambodia, it lasts only an average of 24 minutes. In June, it's about 25 minutes in Phnom Penh, while in December it's 24 minutes.

The sun between the tropics

The capital Phnom Penh is located at 12 degrees north latitude and therefore also between the tropics. The sun swings back and forth between them over the course of the year. At the solstice on June 21, it is perpendicular above the northern tropic, and on December 21 above the southern tropic. If a country like Cambodia lies between these tropics, the sun crosses its latitude twice a year and then shines vertically from above. For Phnom Penh, this is on April 21st and August 23rd. In between, the sun shines from the north, otherwise from the south. In Paôy Pêt, around 350 km away, it is April 27th and August 17th.

Unlike in countries that are far away from the equator, the angle of the sun is quite large here. The sun is much higher in the sky at midday and therefore shines with a high intensity. It has the smallest angle, i.e. the smallest distance from the horizon, at the winter solstice on December 22nd. Then, even at midday, it is only 55.0 degrees above the southern horizon. For comparison: in New York, the sun only reaches an angle of 73 degrees at the height of summer.

Actual hours of sunshine

The period from sunrise to sunset is the astronomical length of the day. It is therefore independent of whether you can actually see the sun. In addition, significant deviations can be perceived depending on cloud cover or other visual obstructions. For the Phnom Penh resp. Mekong Lowlands region, we have shown the approximate sunshine duration in the graph here.

In June, the sun shines for around 6:24 hours a day. In contrast, the day is 12:50 hours long. This means that the visual obstruction is around 6:26 hours per day. In December, on the other hand, it is 4:11 of 11:29 hours.
