モスクワの月別の天気

The climate of Moscow features warm summers and long, cold winters. Temperatures average below freezing for four months a year, between mid-November and mid to late March. Snow cover typically forms in late November or early December and melts in early April.

Moscow forum regulars are consistent that January runs genuinely cold — readings anywhere from “+3 to -25°C” come up, with “temperatures between +1 and -20 centigrade” the more typical range — but manageable because even if it's freezing outside, indoor spaces run “oppressively hot,” so managing layers matters more than the outdoor number alone. Days are short with very little sun, and rain is rare — “rainy days in Moscow in January are rare phenomena,” which some frame as a plus for a winter trip. The trade regulars emphasize: fewer tourists, cheaper flights and hotels, against real cold that needs waterproof, grippy boots and proper layering, not a single heavy coat. Our record: -3.9°C days, -7.9°C nights, 41cm of snow across the month and just 1 hour of sun a day — cold and dark, matching the forum's read closely.

Moscow forum threads describe February as genuinely cold and unpredictable, with days swinging anywhere from around +4C down to -25C depending on the specific week, though a more typical run was described as hovering in the -2 to -5C range with periods of slush and melt in the city center rather than deep snow cover. Posters were consistent that a proper warm coat, waterproof boots, gloves, hat and scarf are non-negotiable for walking around. The more surprising theme across threads: the real discomfort often comes from overheating indoors, since buildings, metro cars and buses run heated, so visitors constantly unbutton or shed coats indoors and bundle back up stepping outside.

May here splits on a date. The 1st to the 9th is a holiday stretch ending in Victory Day: traffic and business go quiet and rooms can be cheaper, while parades fill the centre and restaurants and hotels are packed. The second half is the quieter half, with the trees out and the visitor numbers still low. Our row gives 17.7C by day reading as 16C, 7.2C nights that feel like 4C, and 0.8cm still sitting in the snow column as the tail of winter. Rain is 61.2mm across 11.3 days. The compensation is light, 16.3 hours of it. The lilacs come at the very end of the month and into June. The record: humidity 65 percent, 11.3 hours of sun and AQI 58.

Asked whether this city has white nights, regulars give the careful answer: not the real thing, which belongs to St Petersburg three hundred miles north, but nautical twilight all night - the horizon stays visible and it never goes properly dark. Their figures for the longest day are sunrise at 04:45 and sunset at 22:18, and our daylight column agrees at 17.5 hours. The weather underneath it is mild rather than warm, 22.6C by day and 12.4C at night, with 72mm of rain across 11.5 days, so showers on a third of them. Evenings have become warm by June in a way May's are not. The record: humidity 67 percent, 12.2 hours of sun and AQI 59.

Moscow's July, per the forum: warm rather than reliably hot, with an average high near 23°C and days that can climb to 30, then fall back to 12–15°C overnight — the city is a long way from any ocean, so the month swings between hot and sticky and unexpectedly chilly. Rain is frequent enough, around 13 days, that regulars pack a windproof, waterproof layer alongside summer clothes. Two practical notes they repeat: air conditioning is far from universal here, and several posters would rather have late August or early September — still warm, less hot, fewer tourists.

August in Moscow is the part of the year that feels warmest, because the humidity is higher than in July and there are few days when you want an added layer. The forum attaches two qualifications. Rain is a very good chance rather than a possibility - our row carries 10.3 precipitation days - and there is the turn: in the second half of the month you can feel autumn arriving, a little colder each day, with early mornings, late evenings and the hour after a shower the parts that bite. A windbreaker rather than a winter jacket is the standing answer. On crowds, regulars give 15 July to 20 August as the quiet window, after which the city comes back and the last week is heaving. The record: 23.5C days, 13.6C nights, 60.2mm of rain and 10.9 hours of sun.

Regulars are direct that nothing is certain this month - one traveller's own account describes a pleasant, t-shirt-worthy 24C one day followed immediately by an icy 8C with wind and rain the next. Our row backs the average sitting between those extremes, 17.3C over 8.8C nights, with 43.2mm of rain across 8.2 days. Regulars are split on recent trends, some calling it warm and largely rain-free lately, others still expecting real rain as a baseline assumption - the honest advice from most is to plan for anything and dress in real layers rather than trust either extreme. Late August into early September is specifically recommended as schools return and the heaviest tourist crowds thin out. The record: humidity 73 percent, 7.5 hours of sun, a 17.6 kph wind and AQI 59.
