Swaziland's climate is moderate, near-temperate, subtropical, and semi-arid. This makes it similar to that of the middle Atlantic states but drier and with the seasons reversed.

Due to the variations in altitude the weather is changeable. Except in the lowland it is rarely uncomfortably hot and nowhere very cold, although frosts occasionally occur in the Highveld which has a wetter, temperate climate. The Middleveld and Lubombo are drier and subtropical with most rain from October to March.
