Welcome to Sweers Island


Sweers Island's climate could best be described as 'Dry Tropics'. The average daily maximum temperature ranges from 24C in June/July to 35C in December. The most pleasant times to visit the Gulf Country are from early April until mid October. During this time, south-easterly winds prevail and can sometimes blow up to 25 knots in the morning and drop off to flat calm in the afternoon. These winds can be chilly at night, so from May to September it is advisable to bring at least a warm jacket & jeans for evenings. The Morning Glory Roll Cloud is often seen in this area during September-October.
