The standard answer to 'when should I go to Morocco' is autumn or spring. It is correct in the way that most generalisations are correct: technically true and nearly useless for planning a specific trip. The better question is what you are going to Morocco to do, because the right time for a Sahara trek differs from the right time for an Atlantic coast surf week, which differs again from the right time for an Atlas Mountain traverse, which differs from the right time for a Marrakech-based programme that involves hammam, cuisine, and the medina.

October and November are the Sahara months. The summer heat has broken. Daytime temperatures in Erg Chigaga settle at 28 to 32 degrees Celsius, warm, comfortable for walking, cold enough at night (8 to 12 degrees) to require a proper sleeping layer. The sand is firm from the summer wind patterns. The light in October is at its most horizontal and golden from about 4pm, which creates conditions for photography that photographers from Europe and North America find extraordinary. The galactic core is well-positioned in the southern sky through October and into November. Erg Chigaga in October is as good as it gets.

December is underrated. Marrakech in December is 18 degrees and clear. The medina is not crowded. The Atlas is accessible from Imlil, with the first snow on the high ridges creating a landscape that most visitors associate with Switzerland, not Morocco. The Drâa Valley south of Ouarzazate is green from the autumn rains. Hammam weather, when you appreciate the heat rather than merely tolerating it, arrives in December. The food in December is at its best: *tagine* with preserved lemon and *chermoula*-marinated vegetables from the autumn harvest, citrus just coming into season from the Souss plains.

January and February are the Atlantic months. The southwest swell peaks between these two months, generating the best surf conditions of the year along the coast between Essaouira and Agadir. The water temperature drops to 16 to 18 degrees, a 3mm wetsuit is sufficient, and the line-ups are quiet. The wind from the northeast, the *chergui*, is less prevalent in January than in summer, which means cleaner wave faces. If you are combining yoga and surf, or surf and breath work, January and February on the Atlantic coast are the structurally correct months.

February and March are the flowering months. The Drâa Valley south of Ouarzazate is pink with almond blossom in February, a two-week window that is as visually extraordinary as the Japanese cherry blossom season and receives a fraction of the attention. March brings argan blossom in the Sous-Massa region southwest of Agadir. The valleys are green. The Atlas passes are clearing of snow. The light is long and climbing toward the summer angle. This is the correct window for anyone whose priority is the landscape as aesthetic experience.

April is the closing month of the retreat season for a reason. The light is extraordinary: long and golden. The heat has arrived but has not yet hardened into the punishing July levels. The wildflowers in the High Atlas valleys are at peak. The Sahara is already warming toward uncomfortable midday temperatures, which means April Sahara programmes need to be structured around dawn and dusk movement rather than midday walking. April Atlantic is still good surf. April Marrakech is warm enough for riad courtyards and cool enough for medina walking in the afternoon.

May through September is honest about its limitations. June, July, and August in the Sahara region reach 44 to 48 degrees Celsius midday. In the medina of Marrakech, 38 to 42 degrees in July. The Atlas above 3,000 metres is comfortable in summer, and July and August are the peak months for Toubkal ascents (the snow has cleared; the route is trail rather than snowfield). But the Sahara and the lowland cities require heat adaptation that most visitors from Northern Europe or North America do not have. September is a genuine exception: the heat breaks in the Sahara in early September, the Atlantic swell begins to build, and the Atlas season opens for the autumn window.

Ramadan, which shifts approximately eleven days earlier each year relative to the Gregorian calendar, deserves specific planning consideration. During Ramadan, most Moroccans fast from dawn to sunset. Restaurant hours change. The medina atmosphere in the hour before *iftar*, the breaking of the fast, is extraordinary: markets full, the smell of *harira* and *chebakia* (sesame and honey pastries) everywhere, a communal anticipation that is worth experiencing. Retreats scheduled during Ramadan require culinary adjustment (most retreat kitchens serve food all day regardless) and benefit from building *iftar* into the group evening as a cultural experience rather than an inconvenience.

A practical note on shoulder-season transitions: the Moroccan climate, like most Mediterranean and semi-arid systems, is not entirely predictable at the margins. The October weather window that was perfect for the previous three years can deliver a frontal system that closes the Sahara camps for two days. The March bloom that peaked in February one year may not arrive until mid-March the next. Building flexibility, either in travel dates or in programme design, into any spring or autumn retreat is the difference between frustration and discovery. Weather that closes one plan almost always opens another.

Umnya's retreat calendar is built around these seasonal logics. The Sahara programme runs October and November. Atlas weeks run October, November, and March. Atlantic coast weeks run January and February. Marrakech sessions run December and April. The sequencing is not arbitrary: each programme is designed for the specific light, temperature, and landscape qualities of its month. Booking enquiries that specify a month before an activity are often better served by inverting the question: tell us what you want from the week, solitude, altitude, surf, thermal contrast, bloom season, and we will tell you the month.
