Ngwasi is a collection point on Lake Malawi's Tanzanian shore, about 10 km south of Isanga Bay.
Where it is
Ngwasi is on the eastern shore of Lake Malawi, in its northern third (48 mi south of the lake's northern tip).
Nearest collection points: Ukenju 2.1 mi south-east · Cape Kaiser 4.3 mi north-west · Lukuyusi 4.8 mi north
Shore, third and distances are measured from the coordinates above against the lake’s mapped outline.
The water
Lake-wide measured chemistry of Lake Malawi — collection points share their lake's water; site-specific figures are shown only where the literature records them.
Nearest measured station: Salima (south-east shore) (~398 km) — Conductivity 235 µS/cm
Surface temperature here
Across May–Nov, monthly means run 77 °F to 82 °F — coolest in Aug. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (1015 clear days). The rainy-season months are usually too cloudy to measure and are left blank.
Temperature: ESA Climate Change Initiative, Lakes_cci v3.0 (Asfour et al. 2026; doi:10.5285/a56dba09df8a42ec9fba8b8c7a5e1f69). Chemistry on this page remains the lake's own.
Each entry below is the population of that species recorded here — the form aquarists keep and breed as a distinct, provenance-labelled line. Crossing forms from different collection points is considered hybridisation in the hobby.
