Tamale, Ghana · UTC+0 ☆

Tamale is the capital of Ghana’s Northern Region and the country’s fourth-largest city, sitting in the broad savanna of the upper Guinea coast interior. It runs on Greenwich Mean Time (UTC+0) all year, with no daylight saving. At about 9 degrees north and roughly 0.8 degrees west longitude, Tamale sits almost exactly on the prime meridian, making GMT a near-perfect solar alignment.

Ghana straddles the prime meridian, and Tamale’s position means local solar noon falls within minutes of noon on the clock. This alignment is unusual: most cities with GMT offsets are not actually at zero longitude, and the difference between clock noon and solar noon is a small but real offset for them. Tamale barely has that offset.

The city is the commercial and administrative hub of northern Ghana, which is culturally and economically distinct from the more industrialized south. Market activity is central: Tamale’s daily market and the larger weekly Katampe market attract traders from across the region. Market days organize the commercial week in a way that parallel the official seven-day clock.

Tamale has a predominantly Muslim population in the north, and the call to prayer marks the day’s rhythmic structure alongside any clock schedule.

Takoradi and Accra in the south share the same GMT offset.

9am in Tamale is 9am in London in winter, with a one-hour gap opening during British Summer Time.
