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.

Surface temperature here

Across May–Nov, monthly means run 76 °F to 82 °F — coolest in Aug. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (937 clear days). The rainy-season months are usually too cloudy to measure and are left blank.
