Taller is more comfortable. The brighter bars are the best months; the filled label is this month.

Comfort uses the typical daytime high (most comfortable at 20 to 28°C) and the typical rainfall (most comfortable under 1 mm a day), averaged over 2001–2020. Highs and lows are worked out from the monthly average temperature and the average daily swing, so they are close, not exact. It is not a forecast. Humidity, crowds, prices and festivals are not included, and a mountain or coast can differ from its half-degree grid cell.
