Weather in Prague in September: What to Expect (+Local Tips)

Prague in September is a city in transition, basking in the golden light of early autumn. The intense heat of summer gives way to pleasantly mild days, the peak-season crowds begin to thin, and a cozy, romantic atmosphere descends upon the city.

It’s a month of wine festivals, crisp evenings, and some of the best light for photography all year. This guide covers what to expect from the weather and the best ways to enjoy this beautiful month.

Is September a good time to visit Prague?

Yes, September is one of the best months to visit Prague. Many locals consider it their favourite time of year, offering a perfect blend of comfortable weather and a more relaxed atmosphere.

Pros:

• Pleasantly mild and comfortable temperatures for walking.
• Significantly fewer crowds than in the summer months.
• Lower prices for flights and accommodation as the shoulder season begins.
• Beautiful, soft autumn light, known as the “golden hour.”
• The start of wine harvest festivals (vinobraní).

Cons:

• The weather can be unpredictable; you might get warm summer-like days or cool, crisp autumn weather.
• Evenings and mornings are noticeably cooler.
• Daylight hours are shorter than in summer.

Local’s tip: September is all about the wine. Don’t miss the chance to try burčák, a young, partially fermented Moravian wine that is dangerously delicious and only available for a few weeks a year. You’ll find it at wine festivals and farmer’s markets.

Prague Weather in September (Overview)

September weather is best described as changeable but generally pleasant. The first half of the month often retains a warm, summer-like feel, while the second half ushers in the distinct crispness of autumn.

Before we dive into the details, here’s a quick overview of what you can typically expect from the weather in Prague during September.

Weather Metric	Average Figure	Range
High Temperature	19°C / 66°F	14–24°C (57–75°F)
Low Temperature	9°C / 48°F	5–13°C (41–55°F)
Daily Sunshine	Approx. 5-6 hours
Monthly Rainfall	Approx. 40 mm / 1.6 inches
Rainy Days	Approx. 9–12 days

A Deep Dive into September Temperatures

September is a tale of two halves. What you experience can depend heavily on whether you visit at the beginning or the end of the month.

• Early September: Often feels like a gentle continuation of summer. Daily highs in the low 20s (around 70-75°F) are common, making it perfect for outdoor dining and sightseeing.
• Late September: Autumn makes its presence known. Highs are more likely to be in the mid-teens (around 60-65°F), and you’ll feel a distinct chill in the air, especially in the mornings and after sunset.

The Czech Republic sometimes experiences a warm, dry spell in late September known as babí léto (Indian Summer), which can bring a delightful, unexpected return of warmer weather before autumn truly sets in.

Sunshine, Rain, and Daylight Hours in September

Sunshine

While not as sunny as the summer months, September still offers plenty of bright, pleasant days. The sun is lower in the sky, casting a beautiful golden light over the city’s spires, which is why it’s a favourite month for photographers.

Rainfall

September is significantly drier than the summer months. The dramatic thunderstorms are replaced by a higher chance of lighter, more prolonged showers or drizzle. With an average of 40 mm of rain, you’re likely to experience some wet weather, but it’s less likely to be a complete washout.

Daylight Hours

You’ll notice the days getting shorter quite rapidly throughout September.

• Early September: The sun rises around 6:30 AM and sets around 7:40 PM.
• Late September: The sun rises closer to 7:15 AM and sets as early as 6:40 PM.

What to wear in Prague in September

Layering is the absolute key to comfort in September.

• A mix of tops: Pack both t-shirts and long-sleeved shirts.
• Warm layers: A fleece or a couple of sweaters are essential.
• A versatile jacket: A light, waterproof or water-resistant jacket is perfect. A trench coat or a light utility jacket works well.
• Long trousers or jeans.
• Comfortable, closed-toe shoes like trainers or boots. It’s likely too cool for sandals.
• A scarf is a great accessory for chilly evenings.

Local’s tip: This is the month when Prague locals put away their sandals and start wearing light jackets and scarves. You won’t look out of place in proper autumn attire.
