Mozambique has a tropical to sub-tropical climate. Rainfall distribution in Mozambique follows a north-south gradient, with more rainfall along the coast, where the annual average varies between 800 and 1200 mm. The inland high-altitude areas in the north and central regions receive approximately 1000 mm, whereas the inland central and south areas receive about 600 mm of rainfall. The south of Mozambique is generally drier with an average rainfall lower than 800 mm, decreasing to as low as 300 mm. Temperatures are warmest near the coast, compared with colder temperatures higher inland. Typical average temperatures at the coast are 25°C - 27°C in the summer and 20°C - 23°C in winter. The average temperatures in the southern region are 24°C - 26°C in summer and 20°C - 22°C in winter.

- The number of hot days increased by 25 in the last 40 years, and much of this has occurred during the southern hemisphere autumn.
- Since 1960, mean rainfall decreased by an average of 2.5 mm per month (3.1%) per decade.
- Spatial manifestations are varied, with increased rainfall over the northern regions, highly variable conditions in the central regions, and persistent drought periods coupled with episodic floods in the south.
- The proportion of days with heavy rainfall events have increased by 2.6% per decade or an estimated 25 days per year.
