Het weer in Mekka in mei

Regulars describe this month as hot but manageable if the rites are timed around the evening - one visitor's first week of the month found completing them after Maghrib prayers genuinely bearable despite the daytime heat. Our row backs the heat, 35.7C reading as a hot 35C, over 22.5C nights, with rain a minor presence at 21mm across 3.1 days, and humidity down to a dry 39 percent. Regulars are candid this can be genuinely tough for anyone also fasting during a Ramadan overlap, particularly visitors used to a colder home climate, and the standard advice is avoiding long midday walks in favour of the cooler evening and early morning hours regardless of the specific reason for the trip. The record: 11.4 hours of sun, a 21.3 kph wind and AQI 149.

Regulars comparing this month to peak summer are consistent that it's a far easier stretch for performing the rites, which involve real time outdoors and physical exertion regardless of the season. Our row backs a genuine cooling from summer's extremes, 31.8C over 20.9C nights, with 20.9mm of rain across 3.6 days - a small but real increase over the bone-dry summer months. Regulars note the heat is still present and worth respecting, with hydration and light clothing still the standard advice, just without the added danger of summer's much higher highs and warmer nights that don't cool down. The record: humidity 57 percent, 9.9 hours of sun, a 16.3 kph wind and AQI 86.

December to March is the window regulars recommend, and their description of March is a day with two halves: around 18C at Fajr with a cool breeze, and very hot by the middle of the day. Our row gives 19.4C nights and 32.6C afternoons, a thirteen-degree span at 42 percent humidity, which is why the marble is walkable early and punishing later. Rain is 6.6mm on a single day. Crowd levels here follow the lunar calendar rather than the solar one, so whether March is quiet or at its busiest depends entirely on where Ramadan falls that year - look it up before booking. The record: 10.8 hours of sun, a 21.8 kph wind and AQI 167.

December is the month Makkah regulars name for weather: warm to hot through the middle of the day, cooling from Asr onwards, and genuinely pleasant all night and into Fajr. Our row's 29.1C day against a 17.9C night is that daily arc in two numbers. The practical consequence they draw is to move the tawaf off the midday hours, particularly with children, because marble and open sun together are more than the air temperature suggests. The cost of the good weather is company: December and January are the busiest of the year, with Western and school holidays landing together, higher prices and a full Haram - the hours either side of Fajr are the quietest part, though nobody calls them quiet. The record: 2.5 precipitation days carrying 17.6mm, humidity 57 percent, 9.7 hours of sun and AQI 140.
