Enugu, the capital of Enugu State, sits in southeastern Nigeria at the foot of the Udi escarpment, on a plain in the transition between rainforest and savanna at approximately 6.44°N, 7.50°E. It has a tropical savanna climate (Köppen Aw) — warm and humid — with a long rainy season and a distinct dry season marked by the Harmattan.

There is little seasonal change in temperature: it stays warm year-round, with highs around 31–33°C, hottest in February and March before the rains. The rainy season runs from April to October, bringing heavy afternoon thunderstorms and high humidity, with a peak around July and September and a slight dip in August — the local 'August break'.

There is no true winter, but the dry season from November to February brings warm, sunny days and cooler nights, with much lower humidity and little rain. The Harmattan blows off the Sahara between December and February, hazing the sky, drying the air and bringing the coolest, most comfortable nights of the year.

Enugu receives on the order of 1,700–1,900 mm of rain a year, concentrated in the rainy season from April to October, while December and January are effectively rainless. The heavy rains cause severe gully erosion on the escarpment slopes around the city. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Enugu's setting beneath the Udi escarpment leaves it acutely vulnerable to erosion: the torrential rains of the long wet season carve deep gullies into the soft sandstone hills, a problem that has swallowed roads and buildings across southeastern Nigeria. Its Harmattan season is more pronounced than on the coast, bringing genuinely cool, dry nights.
