Temperatures range from 24 degrees Celsius overnight to around 34 degrees Celsius during the day, and could be called ‘perfect weather’. Coastal temperatures vary little throughout the day, while the interior may top 40 degrees by the day and dramatically drop towards zero in the cool of the night.
The northern summer, or ‘wet’ season (Oct – March), has a temperatures in the mid to high 30′s and high humidity. Visitors from cooler climates may find this challenging, however many visitors love the balmy combination of heat, humidity and long days of sunshine.
