What to Expect
Daytime temperatures around 30°C (86°F) are ideal for full-day outdoor exploration. Keep afternoons flexible as tropical showers are common — they typically clear within an hour.
Rain most often builds later in the day, so mornings are typically the driest window and afternoon showers are more likely.
Weather conditions this month are less ideal compared to other times of the year. Indoor activities or shorter outings may be more comfortable.
