Morocco's weather varies dramatically by region and season. Marrakech and Fes run 20–28°C from March to May and September to November, dropping to 12–18°C in winter. The Sahara desert swings hardest: daytime highs above 30°C even in winter, but nights near freezing October through March. The Atlantic coast stays mild and windy year-round, rarely exceeding 25°C even in August. This guide breaks down actual temperature ranges, rainfall, and regional differences month by month.

Morocco's Four Climate Regions
The Atlantic Coast (Essaouira, Casablanca, Tangier)
The coast runs 16–22°C for most of the year thanks to steady Atlantic trade winds, climbing only to 22–25°C in peak summer. Essaouira in particular rarely feels hot. Rainfall concentrates November through February (60–90mm/month), with July–August essentially dry. Sea temperature stays a brisk 17–20°C year-round — pleasant for a paddle, cold for a long swim.
The Imperial Cities (Marrakech, Fes, Meknes)
Marrakech and Fes see the widest seasonal swing of any city region: 12–18°C in January versus 36–40°C in July and August. Spring and autumn (20–28°C) are genuinely comfortable for full days of walking. Rainfall is light and concentrated November through March; summers are essentially rain-free.
The High Atlas Mountains
The Atlas Mountains run 10–15°C cooler than Marrakech at any given time, with snow above 2,000m from December through March closing some high passes. Summer days reach a pleasant 22–28°C in villages like Imlil, but nights drop to 8–12°C even in July — pack a layer regardless of season.
The Sahara Desert
Merzouga and Erg Chebbi see the most extreme daily range in the country: winter days often hit 20–24°C under full sun, then drop to 2–6°C after dark. Summer days regularly exceed 40°C, sometimes 45°C+, with nights staying a warm 22–26°C. Rainfall is negligible almost every month.
Rainfall & Humidity
Almost all of Morocco's rain falls November through March, with the coast getting noticeably more than the interior. Marrakech averages under 250mm annually — drier than London gets in three months. Humidity is low everywhere except the coast, where sea moisture keeps evenings noticeably damper than inland cities.
UV Index & Sun Exposure
Sun intensity is easy to underestimate in the "mild" months. UV runs very high March through October across the whole country, and altitude makes it worse in the Atlas — sunburn happens fast above 2,000m even when the air feels cool. High-SPF sunscreen and a hat matter in every season, not just summer.

January is coldest nationwide, though "cold" is regional — Marrakech still hits 18°C by day, while Sahara desert nights and High Atlas passes can drop below freezing.
No — Marrakech gets under 250mm of rain annually, most of it November through March. The Atlantic coast is noticeably wetter than the interior, and the Sahara sees almost none year-round.
Summer days regularly exceed 40°C and can pass 45°C in July and August. Winter days are far milder at 20–28°C, though nights drop to 2–6°C — the desert's real extreme is the day-to-night swing, not just the heat.
December and January are wettest, particularly on the Atlantic coast (Essaouira, Casablanca, Tangier). Interior cities and the Sahara stay comparatively dry even in winter.
Only near the coast, where sea moisture keeps evenings noticeably damp. Marrakech, Fes, and the Sahara are dry climates year-round, similar to other North African desert-adjacent regions.
Winter nights (November–February) commonly drop to 2–6°C. Even in summer, desert nights cool to a relatively mild 22–26°C compared with daytime highs above 40°C — pack a warm layer regardless of season.
