See descriptions below for a general summary of what conditions to expect on average at different times of the year.
Generally speaking we have two seasons: Easterly winds from June to October, and Westerly winds between December to April. November and May are usually transitional months. July and August see a slight increase in wind, and the sea ripples somewhat, visibility is still fine. The weather in these months is a little cooler than the months on either side, making it a great time to visit for those who prefer to sleep without using an A/C at night (book a Beach Bungalow on the South beach to enjoy the breeze).
