Sun questions for Surabaya

How high does the sun get in Surabaya?

Surabaya is in the tropics (7.3° S), so the noon sun passes directly overhead — leaving almost no shadow — around 2 March and 12 October. It is lowest at the June solstice, reaching 59.3° above the horizon at solar noon.

How long is twilight in Surabaya?

Civil twilight — from first light until sunrise, when you can still see outdoors without lights — lasts about 21 minutes around the equinoxes and 23 minutes at midsummer in Surabaya. Close to the equator the sun climbs steeply, so dusk turns to night quickly.

When is the earliest sunrise and latest sunset in Surabaya?

The earliest sunrise is at 05:01 around 8 November and the latest sunset at 17:56 around 26 January. They don't fall on the solstice itself because solar noon drifts by up to a quarter of an hour through the year (the equation of time).

How fast do the days get longer or shorter in Surabaya?

Very slowly. Near the equator day length changes by at most 24s from one day to the next.
