Map - Suriname

Suriname, the former Dutch Guiana, has almost everywhere an equatorial climate, hot and humid throughout the year, with heavy rains, in fact it is covered with rainforests and mangroves.
However, in most of the country there is a rainy season from December to mid-August (with a relative decrease in February and March and a peak in May and June), and a relatively dry season from late August to mid-November.
In the capital Paramaribo, located on the coast, an average of 87 inches of rain falls per year; the rainiest months are May and June, when the rainfall reaches 12 inches per month, and when it rains almost every day. Here is the average precipitation.

The rainiest regions are the east, along the Maroni River on the border with French Guyana, where the average precipitation reaches 100 inches per year, and the south-central, at the foot of the Wilhelmina mountains, whose highest point is Julianatop, 4,200 feet high, where the rainfall reaches 120 inches per year.
In the far south, in the Sipaliwini Savanna Nature Reserve, the dry season is longer, so the climate becomes tropical, and the land is covered by savannah, as the name suggests. Here the rainfall stays below 4 inches per month from September to December, and just above this level in August, January and February.
As mentioned, in Suriname it's hot all year round. In Paramaribo, the average daily temperature ranges from 79 degrees Fahrenheit in the cooler months (December to March), to 82.5 °F in the hottest months (September and October).
Here are the average temperatures of Paramaribo.

The amount of sunshine is not so high from December to May, when there are on average 6 hours of sunshine per day in Paramaribo, while it is good in the driest period, late August to mid-November, when there are 9 hours of sunshine per day.
Suriname lies outside of the hurricane belt, because they pass over the Caribbean, hence north of the country.


When to go

The best time to visit Suriname runs from late August to mid-November, which is the driest and sunniest; even though it is also the hottest, because here it's more advisable to avoid the heavy rains.
The little dry season, from February to March, is less pronounced, but it is still quite noticeable at least along the north coast, especially from Paramaribo to the west, that is, to the border with Guyana. This is however a less sunny period than the former, and besides, depending on the year, the rains can sometimes be heavy.
In the far south, the Sipaliwini Savanna can be visited for a longer period, from August to February, with a preference for the period from September to December.

What to pack

Throughout the year: tropics-friendly, loose fitting clothing, light shirts and pants of natural fibers (cotton, linen) or synthetics that breathe, to be washed often, maybe with long sleeves for mosquitoes; a light sweatshirt for the evening; sun hat; umbrella or light and breathable raincoat.
From December to March, a sweater for the evening.
