Weather in Casablanca in August

Prime time. If you get to pick your dates, August is the one. Highs average 31.1 °C, lows 21.2 °C, and rain falls on 1 days — nothing in the month is working against you.

Casablanca barely has seasons. August scores 80 out of 100 against a best of 93 in June — a gap small enough that the month you choose matters far less here than the week you choose. Worth keeping in perspective: August is the weakest month of Casablanca's year and it is still a perfectly good one. The downside here is small.

Rain falls on only 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 31.1 °C days and 21.2 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 18 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest August day reached 44.3 °C and the coldest night fell to 17.9 °C.

August is dependably dry, and that reliability is the point: across the twenty years measured, the wettest August on record still only managed 22 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Augusts brought 8 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 10.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.

How August sits in the year

This is a turning point in the year — July and September sit on opposite sides of it, so the month contains the change rather than following it.

Daylight in August

13.4 hours of daylight, losing 0.9 hours across the month. That is between Casablanca's extremes of 14.4 and 9.9 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 23.5 °C in August — comfortable for a proper swim. This is the warmest the water gets all year.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

August in Casablanca versus nearby

If Casablanca is one option among several, the nearby comparison is worth making. Marrakesh is the weaker option in August — 9.4 °C warmer, 1 day more rain. Fes is the weaker option in August — 8 °C warmer, 1 day more rain.

So: August works, with June the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
