Your April weather guide
CoolWeather in Prague in April
Prague in April suits a city break built around walking, provided you pack for cool weather rather than spring warmth. Average daytime highs are 14.8°C, nights fall to 4.4°C, and about 9 days have rain. That makes it a reasonable choice if you are happy to alternate outdoor time with indoor breaks. The catch is the gap between a pleasant afternoon and a chilly evening: travelling with only light clothes would be a mistake.

Nights average 4.4°C; one night in ten drops to -0.3°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest April day here reached 28.2°C (2012-04-29) and the coldest night -5.0°C (2003-04-09).

Is April a good time to visit Prague?
April is not the strongest month here: cool days and frequent rain. The best months for Prague on our scoring are August, July, June.
Comfortable for walking, cold after dark
Plan around layers you can adjust, with a warm jacket for evenings and something lighter underneath for milder afternoons. The warmest days can reach 21.4°C or more, but that is a bonus rather than a sensible expectation for your whole stay. At the colder end, nights can fall to -0.3°C or lower, so a late return to your accommodation may feel properly cold. April suits travellers who find walking in cool air more comfortable than sightseeing in heat. Put longer outdoor stretches into the warmer part of the day, and do not assume that sunshine means you can leave your jacket behind.
Keep outdoor plans flexible
With about 9 rainy days, April calls for a waterproof jacket, shoes that cope with wet pavements and room to change your plans. Rain need not rule out the trip, but a schedule that depends on staying outdoors throughout would be less practical. There are about 5.7 hours of sunshine within 13.5 hours of daylight, giving you plenty of usable daylight without a promise of clear skies. Keep indoor options available and use brighter spells for longer walks. The useful distinction is between a workable city-break month and a warm-weather holiday: April offers the former, while reliable warmth is not its strength.
