Siyeswe Bay is a bay on Lake Tanganyika's Tanzanian shore, about 1 km south-east of Kahinfiye Bay.

Where it is

Siyeswe Bay is on the eastern shore of Lake Tanganyika, in its central third (205 mi south of the lake's northern tip).

Nearest collection points: Lufungu Bay 2.2 mi north-west · Nkwasi Point 3.5 mi north-west · Lumbye Bay 4.1 mi south-east

Shore, third and distances are measured from the coordinates above against the lake’s mapped outline.

The water

Lake-wide measured chemistry of Lake Tanganyika — collection points share their lake's water; site-specific figures are shown only where the literature records them.

Surface temperature here

Across May–Oct, monthly means run 77 °F to 80 °F — coolest in Aug. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (1056 clear days). The rainy-season months are usually too cloudy to measure and are left blank.
