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.
October is the driest month, with rain on 26% of days and daytime highs near 12.8°C (55°F). June is the wettest, at 42%. Temperature swings hard across the year — 29.2°C between July (26.3°C / 79°F) and January (-2.9°C / 27°F) — so packing for the wrong month is the main risk. The record rules out too cold in Nov–Feb.
