The climate varies from tropical to near temperate. The seasons are the reverse of those in the Northern Hemisphere with December being mid-summer and June mid-winter. Generally speaking, rain falls mostly during the summer months, often in the form of thunderstorms. Winter is the dry season. Annual rainfall is highest on the Highveld in the west, between 1,000 and 2,000 mm (39.4 and 78.7 in) depending on the year. The further east, the less rain, with the Lowveld recording 500 to 900 mm (19.7 to 35.4 in) per annum. Variations in temperature are also related to the altitude of the different regions. The Highveld temperature is temperate and seldom uncomfortably hot while the Lowveld may record temperatures around 40 °C (104 °F) in summer.

The terrain largely consists of mountains and hills, with some moderately sloping plains. The lowest point is the Great Usutu River at 21 metres (69 ft), and the highest is Emlembe at 1,862 metres (6,109 ft).

As a landlocked country, Eswatini has neither coastline nor maritime claims. In terms of land boundaries, Eswatini borders Mozambique for 105 kilometres (65 mi) and South Africa for 430 kilometres (270 mi), giving a total land boundary length of 535 kilometres (332 mi).

Eswatini is prone to floods and drought. Soil erosion as a result of overgrazing is a growing problem.

Eswatini is part of the following international agreements: Biodiversity, Endangered Species, Nuclear Test Ban and Ozone Layer Protection. The country has signed, but not ratified the agreement on desertification and the law of the sea.
