Best Time to Visit Prague: Weather by Month, Crowds, Events

The best months to visit Prague are May and September: daytime highs in the centre reach 20–21 °C and hotels host 6–10% fewer guests than in peak August and December. September is drier than May, with 34 mm of rain against 58 mm. January and February are the quietest, with under 500,000 guests a month against 793,000 in August. Around Prague checked the weather against ČHMÚ data, visitor numbers against ČSÚ data and event dates on official websites on 30 October 2026.

Prague weather by month

The table shows averages for 1991–2020, the current climate normal period, at the Praha-Klementinum station in the Old Town next to Charles Bridge (191 m). We found no ready-made table for it on the ČHMÚ website, so we calculated averages from ČHMÚ open data.

A rainy day means at least 1 mm. The centre averages 16 days of 30 °C or more a year, 7 of them in July. At the Praha-Ruzyně station by the airport (364 m) the annual average is 9.0 °C, matching the official ČHMÚ normal for Prague and Central Bohemia. The centre is 2.3 °C warmer at 11.3 °C. The climate is warming: the centre averaged 12.1 °C in 2011–2023.

A white Christmas is rare: in those 30 years, at least 1 cm of snow lay on any day of 24–26 December 4 times in the centre and 12 times at the airport.

When Prague is busiest

ČSÚ, the Czech Statistical Office, counts guests in hotels, guesthouses and other places with at least 5 rooms and 10 beds. Small Airbnb-style flats and day-trippers are not included. The latest full year is 2025, with a record 8.28 million guests. Stays per day is our calculation: monthly stays divided by days. Season limits are also ours: low under 500,000 guests, shoulder 600,000–680,000, high 700,000–750,000, peak 775,000 or more.

August and December are almost level, and December has the most overnight stays. October comes third. Foreign guests peak in August and December, Czech residents in November and October. US guests peak in June and September, UK guests in December. January–August 2026 brought 5.42 million guests, up 1.8% on a year earlier (our calculation).

When Prague is most expensive and crowded

We found no official monthly hotel prices for Prague alone. The closest measure is the hotel price index for all of Czechia (Eurostat, 2025 = 100): in 2025 it stood at 94.3 in January, 102.8 in May and 101.7 in December. Part of that gap is general price growth, not the season. Cushman & Wakefield, citing STR, puts the average Prague room at €123 in 2025 with occupancy of almost 77%, and above 80% for six months of the year. There are no weekly figures, so check New Year and Easter rates with hotels.

• December: markets and the most overnight stays of the year. Book early for the holidays.
• August: the most guests and an average of 5 hot days.
• Easter, 26–29 March 2027: when Easter moved from March to April in 2025, March lost 42,000 guests and April gained 54,000 (our calculation against 2024).
• 1–2 May 2027: the marathon runs through the historic centre, with United Islands nearby.

What to pack

• December–February: warm coat, hat, shoes with good grip.
• March–April: layers and a windproof jacket, for 3 °C on March nights to 16 °C on April days.
• May–August: light clothes, a rain jacket or umbrella, sunscreen. These are the wettest months.
• September–November: a jumper and a waterproof jacket.
• All year: comfortable flat shoes for the cobbles.
