Humid subtropical (mild with no dry season, hot summer, lat. 20-35°N) - Unbearably hot dry periods in summer, but passive cooling is possible - **Note that the Köppen classification shown here is derived algorithmically from the source weather data. - It may not be indicative of the long term climate for this location. - Climate type "2A" (ASHRAE Standards 90.1-2004 and 90.2-2004 Climate Zone)** - Hot - Humid, Probable Köppen classification=Cfa, Humid Subtropical (Warm Summer) -
