What is the best month to visit Meknes?

If you want a single answer, I'll give you two months and a reason for each: April and October are the best times to visit Meknes, and choosing between them comes down to what scenery you want. Both sit in that perfect band where daytime highs hover at a comfortable 24–27°C, nights are mild, the air is dry and clear, and the few tourists who reach Meknes are at their fewest. For an inland imperial city that swings between hot summers and cold, wet winters, these shoulder months are unambiguously the sweet spot.

I'd nudge a first-timer toward April for the landscapes. After the winter rains, the Saiss plains around Meknes are a vivid green stitched with red poppies and wildflowers, and the Roman ruins of Volubilis — your essential half-day pairing — stand in blossoming grass with storks nesting overhead. It's the most photogenic Meknes ever looks, the sightseeing weather is faultless, and the warmth is reliable by late April. For green, flowers and gentle sun, April wins.

October is my pick for atmosphere and food. The weather is just as kind, but you arrive at the climax of the agricultural year — the grape harvest is wrapping up and the olive harvest is starting, since this is the heart of Morocco's wine and olive country. The markets overflow, the vineyards are busy, the countryside has a warm, abundant, golden feel, and pairing the city with a vineyard visit is at its richest. For harvest atmosphere and the same superb weather, October is the one.

What I steer people away from is the extremes. July and August bring 33–37°C heat that turns midday sightseeing and the shadeless ruins of Volubilis into hard work, even if the nights stay pleasant and the city is quiet. December through February are cold (14–17°C days, single-digit nights) and properly wet, beautiful in their green way but demanding warm layers and patience with grey skies. So: aim for April or October, fall back to May, September or early November, and treat summer and winter as for travellers with fixed dates or a taste for the off-season.
