When to go by season
January to February
This period is known as a short dry season, and is an ideal time to visit the north, when road conditions are more favourable.
March to April
This shorter rainy season is less ideal for those planning to visit the rainforests, and those who decide to visit during this time should pack with rainy conditions in mind.
May to September
Generally perceived as the best time to visit the south, this is the longer dry season when it is easier to visit. In the north however these are some of the wettest months so when you visit will depend on which areas you wish to see.
October to December
A longer rainy season, this is less ideal for those visiting the southern region, but in the north the rain starts to subside, entering a drier period in the new year.
