The climate of Tunis

Geographically nestled on the Mediterranean Sea's north coast, Tunis is chartered under the Csa category by the Köppen climate classification. This nomination affirms its prevalent Mediterranean weather characterised by hot summers and mild winters. A captivating mix of climatological parameters all year round deftly demonstrates this.

Spanning January through December, air temperatures stage a notable progression, ascending from a cool 16.2°C (61.2°F) in January, gradually accelerating to a blistering 34.4°C (93.9°F) heat peak in July and August, then descending back to a milder 17.5°C (63.5°F) come December. Night temperatures mirror this trend, though typically cooler, gamely fluctuating between a chilly 8.5°C (47.3°F) in January and evolving to a warm 22.9°C (73.2°F) in August.

The drama of rainfall tends to favour the colder months, evidenced by a conspicuous increase from a negligible 3mm (0.12") in July to a substantial 67mm (2.64") in December. Sunshine hours optimally maximise to an impressive 11.5 hours in July then retreat to a lowly 4.8 hours in December. The dominant presence of the Mediterranean Sea profoundly influences sea surface temperatures, promoting gradual shifts from 15°C (59°F) in January to 26°C (78.8°F) by August.

Such weather components ensure that the hot summers nurture the land with plentiful sunshine, offset by mild winters interspersed with ample rainfall.
