Cambodia's national averages run from 31 °C in December to 35 °C in April, with rainfall between 15 mm in February and 328 mm in September and 3.6–8.5 hours of sun a day. Against the default preferences (under 2.7 mm of rain a day, at least 6 hours of sun), the strongest months are January, November and December. Its 24 regions span 30–34 °C in annual mean temperature, so the national figure hides a good deal.
