By the time September comes to Prague, the summer tourist season has passed, and with it, the glut of tourists that choke Prague's attractions and fill the city's restaurants. The hottest months in the year have gone away and the weather begins to cool down as summer merges into autumn.

During the last bit of warmth of the season, you can enjoy everything from classical music and wine festivals to one of Prague's historic cafes to a walking tour of the historic sites in Old Town, many of which are only accessible by foot. Prague offers numerous opportunities to get a view from above, from the tower on Charles Bridge to the lookout in Old Town Hall. With fewer fellow travelers, you'll have a better chance to enjoy these panoramic views and other activities than you would in the summer.

Prague Weather in September

The approach of autumn in September brings falling temperatures, but it's also sunnier. The days are getting shorter, but even by the end of the month, Prague still offers almost 12 hours of daylight.

  • Average high: 65 degrees Fahrenheit (19 degrees Celsius)
  • Average low: 47 degrees Fahrenheit (8 degrees Celsius)
  • Average number of rainy days: 15
  • Average hours of sunshine: 6 hours each day

If you are hoping for the most comfortable temperatures, plan your visit between mid-September and mid-October—during this time there is less rain as well. The nice climate makes September a favorite time of year to visit Prague for many travelers, especially those who try to avoid the busiest travel seasons.

What to Pack 

When you travel to Prague in September, think layers. You'll start off in the morning needing a jacket or warm sweater and by the afternoon you'll be peeling it off. A scarf tied European style is a chic look and adds warmth. A poncho dresses up jeans for the evening and can be layered over a sweater and a blouse underneath for a triple-layer effect. Take jeans or slacks, long-sleeved tops, and lightweight sweaters. Always bring comfortable, flat shoes for walking with good support.

September Travel Tips

  • September 28 is a public holiday for Day of the Czech Statehood in honor of St. Wenceslas. Sightseeing and entertainment locales should have normal hours, but shops won't be open as many hours as usual.
  • This month is ideal for sightseeing without having to deal with too many crowds. Airfares and hotel rates may be cheaper too, but it's always helpful to book in advance.
  • Lingering bursts of warm days mean that it is still comfortable to eat outside during September, especially at lunchtime. Take any opportunity you get to eat on historic squares or tidy courtyards. On rainy or grey days, enjoy one of the local museums.
