Traveller notes on Prague in May

Other months in Prague

August here runs from the mid-twenties to the low thirties, or turns cool and rainy in the low twenties, and regulars tell you to bring the raincoat either way. Our row gives 26.2C reading as 27C with 83.5mm across 11.5 days - a wetter month than its reputation. The rest of their advice is about people rather than weather: the city is packed, the bridge and the old square are worst on the hour, and the fix is to see them before breakfast and spend the middle of the day in the quarters the crowds skip - the Jewish quarter, Kampa island, Mala Strana, the hill. Nights fall to 16C. The record: humidity 66 percent, 10.5 hours of sun and AQI 51.

Prague-forum threads on December weather describe temperatures typically hovering right around freezing, colder overnight, with the heaviest rains of the year already behind the city by this point in the calendar. Snow is possible but posters call it inconsistent this early in winter - some Decembers deliver a proper dusting over the Christmas markets, others stay grey and dry underfoot for weeks at a stretch. Regulars are firm that snow boots and a full parka are overkill; a warm coat, real layers underneath and sturdy walking shoes handle the cobblestones fine. The markets themselves stay lively into the evening, and the main sights and museums run on normal hours throughout, so a short, cold day outside is easily balanced with plenty of indoor options. The record: 5.7C days feeling like 2C, 1.5C nights, 45mm across 10.6 days, 7.3cm of fresh snowfall, 84 percent humidity and just 3.4 hours of sun.

Prague forum regulars describe March honestly as still cold at the start but genuinely rewarding by the sun: “generally cold in early march but, if the sun is shining it is very pleasant and often one of the best times to come here.” Typical mid-March readings run “highs of 8C during the day, lows of 0C at night,” though the range can swing from “minus lots with snow to plus 15” depending on the year. Rain stays relatively low through March and the first half of April before picking up into May. The practical warning that repeats: cobblestones get genuinely slippery when wet, so slip-resistant shoes matter as much as a warm coat. Our record: 10.3°C days, 1°C nights, 8.4 rain days and 2.1cm of snow — cold with real snow risk, matching the “cold start, can turn lovely” read.

Prague forum regulars call June the start of “sandal and short pant weather” with “excellent long days to be outside,” but warn early June specifically has been “very changeable in the last few years, one hot, two cold and raining and the other just cold.” Most agree it should be “warm enough to do without a jacket (or with a light one for the evenings),” with rain a real but not defining possibility. The crowd upside: European school holidays don't kick in until late June, so visitors miss the super peak of tourism that hits in July and August. Our record: 24.7°C days, 14.4°C nights, 13.4 rain days and 16.3 hours of daylight — warm with real rain risk, more consistent than “changeable” implies but matching the jacket-optional read.
