How The Month Feels
Expect mild, workable daytime temperatures (around 19.7°C) and noticeably cooler evenings (near 11.3°C). Rain comes often enough to change the pace, but you’ll still have enough dry time to get through the landmark highlights.
What To Lock In Early
With crowds at a medium level and prices also medium, you don’t need to over-plan, but popular time slots can still fill on a busy day. Keep your museum/underground plans flexible so you can swap outdoor blocks when showers roll in.

Expect around 19.7°C by day and 11.3°C at night, with 61.7 mm of rain across roughly 8.4 rainy days.
Bring layers, comfortable shoes, and one warmer piece for evenings.
Usually yes when weather, price pressure, or crowd dynamics are less predictable. It works better with one anchor booking and room to adjust the rest of the day.
