A few of the warmer afternoons, especially early in August, can reach up near 31 C (88 F).

Late night and early morning low temperatures will be near 14 C (57-58 F) early in August, falling to near 12 C (54 F) near the end of the month.

The record low temperature in Prague during August is 2.8 C (37 F).

Sun and Rain

You can expect 17-18 days this month with sunny, or at least partly sunny skies.

What to Wear in Prague in August?

It is still summer and afternoon temperatures tend to be comfortable to warm, however, nights can still be a bit chilly. 

Jeans and short sleeve shirts work well along with a pair of shorts for the warmer days. 

For the cooler nights and early mornings, you may need a windbreaker, a long-sleeved shirt or two, and perhaps a light sweater.

You should also pack an umbrella for those wet days and don’t forget a good pair of walking shoes.
