Verdict combines mean daytime high with rainy-day frequency. “Rainy days” is the share of days in the month with at least 1 mm of rain.
December is the driest month, with rain on 15% of days and daytime highs near 7.8°C (46°F). May is the wettest, at 41%. Temperature swings hard across the year — 26.5°C between July (32.8°C / 91°F) and January (6.3°C / 43°F) — so packing for the wrong month is the main risk.
