メッカの月別の天気

The local visitor guide for Makkah puts January among the more comfortable months for pilgrims — nights rarely dropping below the low teens °C even in the coolest month, with rain (rare the rest of the year) most likely to fall in short, brief bursts if it comes at all.

The Mecca forum's own February thread pushes back on what visitors expect of Arabia: locals say it can feel genuinely chilly at Fajr and Isha, and one poster performing Umrah in early March measured about 18C at dawn with a cool breeze. December through March is the window regulars name as the good months to come. Packing advice is thin cotton shirts and loose trousers, three-quarter lengths being popular, plus a cap for the midday sun; for women the abaya is not a requirement, modest dress is, and most wear their own national dress. The record: 29C days, 17.1C nights, humidity near 50 percent, two precipitation days, 10.2 hours of sun - and AQI 104, the number to weigh if crowds and dust are hard on your chest.

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.

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.

Mecca forum regulars are unambiguous about July: peak summer heat, readings “around 45°C” by day with nights that don't drop “below 30°C,” a daily range regulars call brutal rather than merely hot. The practical advice is specific — light-colored or white cotton clothing, an umbrella for shade, sunglasses, a cap and sunblock as genuine necessities rather than nice-to-haves. For anyone with flexibility on timing, the calendar comparison offered is blunt: the best window for Umrah is “October till March,” when it's “very cool and pleasant” by contrast. Our record: 39.7°C days, 27°C nights, essentially zero rain and 29% humidity — dry heat at genuine extreme, matching the “peak summer, brutal” read exactly.

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 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.
