You can expect sunny days interspersed with heavy downpours that fall mainly in the afternoon. Daytime temperatures average 29°C (84°F), but can climb to a very hot 32°C (89°F).
Weather conditions in May are good for sunbathing and surfing, but the seawater becomes cloudy and is not so good for snorkelling, scuba diving or kayaking.
Additionally, heavy rain showers can cause slippery conditions so jungle trekking should be approached with some caution.
