Casablanca enjoys one of the gentlest climates of any major Moroccan city. Perched on the Atlantic, it has a mild oceanic-Mediterranean character — the sea acts as a vast thermostat, trimming the extremes off both summer heat and winter cold. You rarely meet the fierce, dry heat of Marrakech or the cold mountain nights of the interior. Instead the year turns through warm, ocean-tempered summers and mild, showery winters, with two reliably comfortable shoulder seasons in between. The figures below are typical, long-run norms rather than a forecast — any given week can run warmer, cooler or wetter — but they give a dependable sense of what to expect.
The short answer
If you want the easiest weather, aim for April to June or September to October. These shoulder months are the most reliable of the year: warm without being humid, generally clear, with the lowest chance of rain and the morning coastal cloud largely gone. Summer (June to September) is pleasant but humid, with grey early mornings; winter (December to February) is mild but the wettest stretch. There is no genuinely "bad" time to come — only trade-offs.
Casablanca by season at a glance
| Season | Typical temps | What it feels like |
|---|---|---|
| Spring Apr–Jun | ~14–24°C | Warm, clear, comfortable. The most reliable window of the year. |
| Summer Jun–Sep | ~18–27°C | Warm not hot, ocean-cooled. Humid mornings; grey coastal cloud burns off by midday. |
| Autumn Sep–Oct | ~16–26°C | Sea still warm, skies clearer, crowds thinning. A close rival to spring. |
| Winter Dec–Feb | ~8–18°C | Mild but the wettest months — rain showers between bright spells. |
Temperatures are approximate typical ranges (rough low–high for the period) and vary year to year.
Month by month
January & February
The coolest and among the wettest weeks of the year, though "cool" here means mild by European standards — daytime highs usually settle in the mid-teens °C, nights dropping towards single figures. Expect a mix of showers, passing fronts and bright clear spells; rarely anything prolonged. A light waterproof and a warm layer for the evenings cover it. Crowds are thin and the city feels unhurried.
March
The turn towards spring. Days lengthen and warm, the rain starts to ease, and the Corniche comes back to life. Still a chance of a shower, but the trend is firmly upward. A good, quieter month to wander the Art-Deco downtown and the Habous quarter before the season picks up.
April, May & June
Prime time. Warm, comfortable days, increasingly reliable sunshine and little rain. The humid morning cloud of high summer hasn't yet set in, so the light is clear and the evenings are pleasant for a seafront stroll or dinner. If you want a single recommendation for a first visit, this is it — and it pairs neatly with onward travel inland or to the coast while the interior is still short of its summer peak.
July & August
High summer, but gentler than Morocco's reputation suggests. The Atlantic keeps Casablanca's afternoons in the comfortable low-to-mid 20s°C while inland cities swelter. The catch is humidity and the morning coastal cloud — a low grey stratus that often hangs over the seafront until late morning before the sun breaks through. Peak season for beach clubs and the Corniche, and the warmest the (still-cool) sea will be all year.
September & October
The other star window. The sea is still warm from summer, the humidity and morning cloud recede, skies turn clearer and the crowds thin out. Days stay warm, evenings soften pleasantly. For many regulars this is the very best time — all the upside of summer warmth with cleaner mornings and an easier feel about the city.
November & December
The slide back into the wet season. November can still serve up fine warm days between fronts; by December the rain is more frequent and the air cooler, though daytime highs generally stay mild. A worthwhile time for an indoor-leaning trip — museums, the Hassan II Mosque, the markets and the city's café culture — with a waterproof on hand.
What to pack, by season
- Spring & autumn: light layers, a breathable long-sleeve for cooler evenings, comfortable walking shoes and sunglasses. A thin jacket for after dark on the breezy Corniche.
- Summer: light, breathable cottons and linens, high-SPF sunscreen and a hat. Add a light layer for the grey, cooler mornings and the ocean breeze, plus swimwear for the beach clubs and seawater pools.
- Winter: a light waterproof or packable rain jacket, a warm mid-layer for the evenings, and water-resistant shoes for showery days. Still pack sunglasses — the bright spells are real.
- All year: modest layers for visiting mosques and quieter quarters, and a windproof outer for the seafront, which runs a touch cooler and breezier than the streets inland.
A few timing notes
The ocean breeze is constant. Casablanca almost always feels a little cooler and fresher on the seafront than the bare temperature suggests — a blessing in summer, something to layer against on a winter evening.
Mornings can mislead in summer. If you wake to grey skies in July or August, don't write the day off — that low coastal cloud typically clears to blue by midday. Plan indoor sights or a slow breakfast for the early hours and save the seafront for the afternoon.
Ramadan moves each year. Because it follows the lunar calendar, the fasting month shifts by roughly eleven days annually and can fall in any season. It changes the daily rhythm more than the weather — always worth checking the dates for your travel window. For more on this, see our Morocco festivals calendar.
Casablanca is a gateway, not just a destination. Most trips begin here and continue inland or down the coast. The seasons that suit Casablanca — spring and autumn above all — also tend to be the kindest windows for the wider circuit. For route ideas, browse our private tours or Morocco travel guides.
Frequently asked
What is the best time of year to visit Casablanca?
For most travellers, spring (roughly April to June) and autumn (roughly September to October) are the sweet spots. The air is warm but not heavy, the famous summer morning cloud has largely lifted, rain is uncommon and the light along the Corniche is at its kindest. These shoulder seasons sidestep both the wettest winter weeks and the humid mornings of high summer.
Is Casablanca hot in summer?
Warm rather than hot. Casablanca sits right on the Atlantic, and the ocean keeps a firm hand on the thermometer — typical summer afternoons hover somewhere around the low-to-mid 20s°C rather than the 38–40°C you'd meet inland in Marrakech or Fès. The trade-off is humidity and a low coastal cloud (locally a kind of morning sea-fog or 'low stratus') that often greys the early hours before burning off by midday.
When is the rainy season in Casablanca?
The wettest stretch falls across the cooler months, broadly November through March, with December to February usually the dampest. Rain tends to arrive as showers and passing fronts rather than relentless downpours, and bright spells are common in between. Pack a light waterproof for a winter visit and you'll rarely be caught out.
Can you swim in the sea at Casablanca?
The unofficial swimming season runs roughly June to September, when sea and air are at their warmest. Be ready for the Atlantic to feel cool even at the height of summer — this is open ocean, not the Mediterranean, so the water stays bracing. Many visitors prefer the beach clubs and seawater pools along the Corniche to the open surf.
Does Ramadan affect a visit to Casablanca?
It can shape the rhythm of your days. Ramadan moves through the calendar by around eleven days each year, so it can land in almost any season — always worth checking the dates for your travel window. During the fasting month many local cafés and restaurants keep daytime hours quieter and the city comes alive after sunset. Visitor-facing hotels, tours and many restaurants continue as normal.
What is the weather like along the Casablanca Corniche?
Milder and breezier than a few streets inland. The ocean breeze is a near-constant companion on the Corniche — welcome on a warm afternoon, cooler than you might expect on a winter evening. Mornings in summer can start under that grey coastal cloud before clearing to blue, so an early seafront walk often rewards a little patience.
