What you gain in September
- ↑Golden morning light on the castle: September's lower sun angle gives Charles Bridge and the Vltava their most photogenic quality of the year
- ↑21°C and long days still: warm enough for terraces and river cruises without summer crowds or prices
- ↑Prices fall 20–30% from August peak while conditions barely change — the best value in the entire calendar
What you sacrifice
- ↓41mm of rain still possible across the month — the odd grey afternoon but nothing sustained
- ↓Business travel picking up as schools restart — midweek hotel prices can remain elevated
- ↓River fog possible in early mornings — beautiful, but a risk for planned photography sessions
