How The Month Feels
May feels mild but changeable, with average daytime temperatures around 19°C and cooler evenings near 9°C. Rain is frequent enough (10.4 rainy days) that you’ll likely want indoor backups, even though sunshine still averages 11.2 hours.

With crowds high and prices medium, it’s smart to reserve any timed or high-demand visits in advance. For flexibility, keep museum-heavy options on standby so rainy days don’t derail your plan.
