Weather & Climate

Located just 11° north of the equator, Tobago enjoys a tropical climate with bright sunshine all year round. The average daytime temperature is 29°C (83°F), with normal maximums in the low to mid-30s. The northeast trade winds cool the island so effectively that air-conditioning is often not the critical essential that visitors might imagine. In fact, air-conditioning is the exception rather than the rule in older properties as their location was invariably chosen to take maximum advantage of the prevailing winds.

Tobago has two seasons. The Dry Season runs between December and May and is normally dry and sunny, although rain can be experienced, particulary overnight and just before dawn. The Wet Season is sometimes known as the Hurricane Season and runs between June and November. Although temperatures are fairly consistent throughout the year, changes in the direction and strength of the winds make the summer months feel hotter than the winter months.

Tobago lies outside the main hurricane belt. Hurricanes do not form at latitudes lower than 10 degrees north or south. Tobago also has fewer autumn storms than the more northerly islands. Prior to Hurricane Flora in 1963, Tobago hadn't experienced a hurricane for a hundred years. Hurricane Ivan, in 2004, uprooted a few trees but caused no major structural damage on the island. All the Caribbean islands to the north of Tobago have regular storms and hurricanes.

We extend our deepest gratitude to Paul Tallet, a regular visitor to Tobago, for his weekly weather forecasts. Paul is an amateur weather enthusiast who does his best to provide a simple guide to the Tobago weather outlook each week. It is therefore only fair to state the disclaimer that neither Paul, nor this website, can guarantee the accuracy of these weather reports.

Tobago lies outside the main hurricane belt, so hurricanes are not a major issue, normally. However, hurricanes further north can affect the island. So, Paul also provides regular warning and updates on impending storm conditions.

Normal weather reports will be found in the Liquid Sunshine topic of our forum. Hurricane warnings can be found in the Hurricane Season topic of the forum. The most recent updates are provided below.

WEATHER ... 17TH MARCH 2019

CHANGEABLE THIS WEEK

There was a fair amount of rain last week ... this was not trade showers, but north easterly rain streamers moving off the rainforests of South America, bringing longer periods of rain to the south east Caribbean. The dry Saharan influence is not always influential enough to prevent this weather and now there is very little dry air over Trinidad, Tobago, Grenada and Barbados.

This week, a fairly deep low pressure is sandwiched between 2 areas of High pressure. One in the north Caribbean and one in the mid to east Atlantic. This will increase pressure gradients and bring gales to most of the Caribbean and particularly in the south west Caribbean where another low pressure system is lurking over Columbia.

I am not sure how far south the gales will go but the surfing sea forecasts indicate that it should stay moderate around Tobago all week.

So this week ... rain streamers off South America are likely to continue and this could bring some lengthy spells of rain to Tobago from time to time, particularly at night because this rain begins it's development over the rainforests in the afternoons before it streams north to north east.

It is not uncommon for one area to have no rain while an area a few miles away gets a good dunking. These rain streamers are quite narrow and sometimes only 50 miles wide and some islands could be under a streamer for hours or up to a day.

There should be plenty of sunshine otherwise.
