When the nights are dark enough for lamp fishing — the next two weeks of the moon, read for the usipa and utaka catch. The moon and the dark hours, not a promise of a catch.
Town Tools builds free, public tools for Nkhata Bay and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.
Usipa and utaka are caught at night with a lamp held over the water — and the lamp works best when the moon is out of the way. Here are the next two weeks of nights, read for the light catch.

Dark nights — good for lamp fishing.
How dark each of the coming nights is for lamp fishing. The dark window is the hours after sunset with no bright moon in the sky — when the lamp’s pull is strongest.
A lamp is held over the water to draw usipa and utaka up to the chilimira net. The light pulls best when the sky itself is dark, so the nights around the new moon — when there is little or no moonlight — are the productive ones, and the week around the full moon is the slow stretch, when the moon's own light competes with the lamp. Fishers on this lake have read the moon this way for generations.
usipa and utaka · the chilimira open-water seine, worked at night by lamplight
On Lake Malawi the chilimira (chirimila) seine is worked two ways: by day for utaka, and at night with light-attraction — kerosene or LED lamps over the water — for the small sardine-like usipa. Because the catch depends on the lamp standing out against a dark sky, the fishery slows around the full moon and concentrates on the dark-moon nights.

This is the moon, not a promise of a catch
This page shows the moon and the dark hours — the pattern fishers read, where dark nights favour the lamp and the full-moon week is the slow one. It does not predict your catch, and a good moon is a good chance, never a guarantee.
The moon is only part of it. Cloud can darken a bright night and let the lamp work; wind, rain and a sudden blow can ruin a dark one — and the open lake can be deadly in rough weather, as the April 2025 boat losses near Likoma showed. Check the wind and the lake crossing conditions before you launch, and never let a good dark night talk you onto bad water.
Moon and sun times are calculated for the waters off Nkhata Bay and can be a few minutes out. Times are shown in the local clock.
The next new moon — the heart of the dark-fishing run — is around Tue 14 Jul.
The next full moon — the bright, slow week — is around Thu 30 Jul.
