Start with the shape of the year
A calendar is useful when it shows trade-offs rather than naming one universal “best” month. In recent observations, July carried the highest average daytime maximum at about 39.7°C, while January had the lowest average night-time minimum at about 6.6°C.
Those two points describe the span of the year, but a journey happens between them. Months around January, February, March, November, December sit closer to a moderate temperature band in this dataset; crowds, prices and seasonal events still require separate checks.
Temperature is only one part of comfort
Rainfall is distributed unevenly. December averaged about 51.7 mm per month in the observation period, while August was the driest at about 0.1 mm.
A monthly average cannot say whether rain will fall during your visit. It can tell you when a flexible indoor alternative and waterproof bag deserve more attention.
Rain changes the route, not just the clothes
Choose dates from the activities that matter most: long outdoor walks, evening streets, museums, food markets or day trips. The same temperature can feel different with wind, shade, humidity and the amount of time spent outside.
Use the city, food and hotel links below to test a real day. If most stops are outdoors, leave more weather margin; if the route has covered streets and museums, a wetter month may remain entirely workable.
Match the month to the kind of day
This page uses completed observations rather than a future forecast. About a week before departure, compare the actual forecast with opening hours, event dates and transport notices.
Check the forecast before departure
Pack for the range between morning and afternoon, not only the headline high. A light layer, sun protection, water and a compact rain option solve more travel days than a rigid seasonal label.
