Weather in Fes in May

Prime time. May is about as good as Fes gets. Highs average 28.5 °C, lows 14.4 °C, and rain falls on 6 days — nothing in the month is working against you.

May ranks 2 of 12 in Fes. Only April scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 28.5 °C days and 14.4 °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: 13 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest May day reached 40.7 °C and the coldest night fell to 6.2 °C, and the wettest single day dropped 35 mm — roughly 92% of the month's rain in one day.

May is moderately variable: 4 mm in the driest year against 115 mm in the wettest, around an average of 38 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 8.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 61%.

How May sits in the year

The month is on the way up: 4.1 °C warmer than April, and June adds another 5.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in May

May is at or near the longest days of Fes's year: 13.9 hours of daylight, gaining 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 32.4 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within May itself the daily swing is 14.1 °C, so mornings and afternoons need different clothes.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

May in Fes versus nearby

If Fes is one option among several, the nearby comparison is worth making. Chefchaouen is close enough to be a coin toss — 3.8 °C cooler, 1 day more rain. Tangier is a better bet in May — 7.6 °C cooler, 1 day less rain.

So: May is effectively as good as it gets here — 2 points behind April, which is inside the margin where the weather stops being the deciding factor and price starts being it.
