Weather in Tangier in September

Prime time. September is about as good as Tangier gets. Highs average 25 °C, lows 20.3 °C, and rain falls on 4 days — nothing in the month is working against you.

September ranks 4 of 12 in Tangier: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. 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 September reaches 30 °C; the day barely swings — 4.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest September day reached 33.4 °C and the coldest night fell to 17.4 °C, and the wettest single day dropped 40 mm — roughly 154% of the month's rain in one day.

This is the volatile part. September rainfall has ranged from 2 mm to 87 mm across the twenty years measured — a 85 mm spread around an average of 26 mm. The average is real but almost no individual September looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 12.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How September sits in the year

The month is on the way down: 2.3 °C cooler than August, with October dropping another 2.5 °C. The first week and the last are not the same trip. Rain is the thing that moves: October brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in September

12.5 hours of daylight, losing 1.1 hours across the month. That is between Tangier's extremes of 14.6 and 9.8 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 22.4 °C in September — comfortable for a proper swim. This is the warmest the water gets all year.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

September in Tangier versus nearby

If Tangier is one option among several, the nearby comparison is worth making. Chefchaouen is the weaker option in September — 5.9 °C warmer, 2 days more rain. Málaga is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: September works, with July the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
