When to Visit Tunis

The coldest month in Tunis, with highs around 16°C (61°F) and lows dipping to 8°C (46°F). Rain falls on perhaps a third of days - nothing torrential, but enough to leave the medina's stone streets slick and gleaming. This is low season for tourism, meaning you'll have the Bardo's mosaics largely to yourself and can negotiate seriously at carpet shops. The humidity sits at 70%, giving the air that damp-chill quality that penetrates lightweight jackets.

Similar temperatures to January - highs of 17°C (63°F), lows of 8°C (46°F) - with slightly less rainfall as winter begins its slow retreat. Almond trees start blooming in the surrounding countryside, and you might catch the first hints of warmth on protected terraces. The sea remains too cold for most swimmers, though you'll see determined locals at La Marsa. Tunis restaurants begin setting up outdoor seating in anticipation of better weather.

Spring announces itself with highs climbing to 19°C (66°F) and lows around 10°C (50°F). Rain becomes more sporadic, though March can still deliver surprise storms that send everyone scurrying under the medina's covered alleyways. The light changes noticeably - sharper, more golden - and the scent of orange blossom begins drifting from suburban orchards. This is when Tunisians start reclaiming their city from winter hibernation.

Perhaps the most balanced month: highs of 22°C (72°F), lows of 12°C (54°F), with rainfall dropping off significantly. The countryside around Tunis turns briefly green before summer browns it out. You'll want layers - mornings can feel almost cool, afternoons warm enough for short sleeves. The jasmine that perfumes evening walks starts flowering. Beach clubs reopen in preparation for the season ahead.

Summer's advance guard arrives with highs of 26°C (79°F) and lows of 16°C (61°F). Rain becomes rare enough to seem notable when it happens. The sea temperature crosses into swimmable territory for most visitors, though locals often wait another month. May evenings in Sidi Bou Said are lovely - warm enough to linger over dinner, cool enough to sleep comfortably. This is when things to do in Tunis expand dramatically as outdoor events resume.

The dry season settles in firmly: highs around 30°C (86°F), lows of 20°C (68°F), with rainfall essentially absent. The humidity stays at 70%, which in the absence of rain creates a particular kind of hazy, heavy atmosphere - noticeable but not debilitating. Morning is the time for active exploration; afternoons belong to cafés and siestas. The medina's covered souks offer natural air conditioning.

Peak summer brings highs of 33°C (91°F) and lows that rarely drop below 22°C (72°F). The heat has a particular quality here - dry, insistent, bouncing off white walls and stone pavements. Locals with means flee to Hammamet or further afield; those who remain move slowly and stay up late. The sea offers the only real relief, though Tunis beaches get crowded on weekends. Evening breezes from the Gulf make waterfront dining pleasant.

Essentially July's twin, with highs of 33°C (91°F) and the same sticky nights. This is when the city feels most foreign to itself - quiet in residential neighborhoods, frantic at tourist nodes. The light is almost violent in its intensity; photographers seek the golden hours with desperation. Interestingly, August has been trending slightly hotter in recent years, with occasional days pushing 40°C (104°F). If you're sensitive to heat, this is not your month.

The turning point: highs slip to 30°C (86°F), nights become more breathable at 21°C (70°F), and the first hints of autumn occasionally appear in late-month breezes. The sea, however, has been warming all summer and reaches its most swimmable temperatures now. Tunisians return from holiday, bringing energy back to the streets. This is arguably the sweet spot - summer's pleasures without its punishments.

Autumn proper arrives with highs of 26°C (79°F) and lows of 17°C (63°F). Rain returns, though irregularly - perhaps one significant storm per week. The countryside shows the first signs of thirst after the dry summer. October light is spectacular, slanting through the medina's narrow streets in ways that photographers chase. It's a decent indication of what winter will bring, but with enough residual warmth to keep outdoor life active.

The seasonal shift accelerates: highs of 21°C (70°F), lows of 13°C (55°F), with rainfall becoming more frequent and occasionally heavy. The first serious storms can flood lower-lying streets temporarily. Tunis restaurants move seating indoors; the scent of charcoal smoke from braziers replaces summer's dust. This is when thoughts turn to harissa-heavy dishes and hot mint tea.

Winter establishes itself with highs of 17°C (63°F) and lows of 9°C (48°F), making it among the wettest months. The humidity at 70% combines with cooler temperatures to create that particular Mediterranean chill that seeps into stone buildings. Christmas sees some European visitors escaping worse weather at home. The medina of Tunis takes on a moody, contemplative atmosphere - worth experiencing if you pack appropriately.
