Weather in Casablanca in January

Prime time. January is about as good as Casablanca gets. Highs average 18.3 °C, lows 10.7 °C, and rain falls on 8 days — nothing in the month is working against you.

Casablanca barely has seasons. January scores 79 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: January is the weakest month of Casablanca's year and it is still a perfectly good one. The downside here is small.

Rain on 8 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average January reaches 30 °C. Across the twenty years measured, the hottest January day reached 26.4 °C and the coldest night fell to 2.2 °C, and the wettest single day dropped 42 mm — roughly 75% of the month's rain in one day.

January is moderately variable: 1 mm in the driest year against 131 mm in the wettest, around an average of 56 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 9.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.

How January sits in the year

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

Daylight in January

January sits at the dark end of Casablanca's year — 10.1 hours of daylight against 14.4 at midsummer, gaining 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 17.6 °C in January — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 23.5 °C in August and bottoms out at 16.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

January in Casablanca versus nearby

If Casablanca is one option among several, the nearby comparison is worth making. Marrakesh is a better bet in January — 2 °C warmer, 3 days less rain. Fes is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: January works, with June the better month by 14 points if the dates can move. If they cannot, nothing here should stop you booking.
