Quick facts

Surabaya is in Indonesia, a country in Asia. For the living forecast here, open World Weather; Surabaya’s population and history are described by the sourced introduction above (from Wikipedia).

Where Surabaya sits on the Earth

At 7.26° south of the equator, Surabaya is about 807.3 km from the equator itself and 9,200 km from its nearest pole — and that puts it inside the tropics, where the sun passes directly overhead twice a year and the yearly swing in day length stays small. Latitude is only the sky’s address, of course: altitude, oceans and winds write the actual weather, which is why two cities on the same parallel can need overcoats in one place and sun hats in the other. The numbers on this page come straight from the town’s own coordinates.

Two consequences of that latitude anyone can test. On the equinox the midday sun stands 82.7° above the horizon here (straight up at the equator, lower the further you go). And because the Earth is a sphere turning once a day, a point at this latitude is carried around its axis at roughly 1,661 km/h — fastest at the equator, nothing at the poles. As for daylight: Surabaya sees its longest day lasts about 12.4 hours of daylight and its shortest about 11.6.

Nearest cities on our list: Yogyakarta (270.2 km to the west-southwest), Denpasar (313 km to the east-southeast), Bandung (568.4 km to the west), Jakarta (661.9 km to the west). Every profile here carries the same arithmetic, so the distances between any two of them can be checked by opening both pages.

The other side of the world: a straight line through the centre of the Earth from Surabaya emerges at 7.26°N, 67.25°W — its antipode. The closest city on our list to that point is Caracas, about 360.1 km away; whether the antipode itself is ocean or land is a good quiz question before you look it up.
