When to go, and when not to
January and February stand out as the best months to visit, combining highs of about 30.7-32.2C with relatively low rainfall of 31-52mm and close to 11 hours of sunshine each day. These conditions make for reliably dry, sunny weather compared with the rest of the year.
The trade-off is that January, February, July, and August are also the peak season, when higher demand can mean busier conditions. Later months bring heavier rain, with September recording 295mm and October 286mm, while April is both wetter, at 122mm, and among the warmer months with highs of 32.7C, so travelers weighing crowds against rain and heat have several months to consider outside the January-February window.
