Tropical downpour

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.

Current Weather

Reflecting on the daily weather over the last 4 weeks, yet again, I have to say that the weather on the ground is not reflected in the satellite images and this has always caused me worry because I can never be sure of what I am seeing when I view the weather from home.

Another factor is that Trinidad & Tobago's weather is unique and not as predictable as the weather around the rest of the Caribbean. The reasons for the uniqueness is that Tobago's weather is often influenced by what is going on in the rain forests of South America, with Guyana and Venezuela being the closest. The rain forests here set off their own weather systems and rain streamers can shoot northwards to north-eastwards over T&T and, to a lesser extent, the Dutch Antilles and Grenada.

This can be enhanced by an almost perpetual low pressure system that sits over Columbia (which is why Columbia is often windy with rough seas) for most of the year which pumps up the moisture from the rain forests towards the south east Caribbean.

So I have to emphasise that my weather updates are based on the general situation. Not even the T&T Meteorological site can predict each day's localised weather accurately, although they were more accurate about sea conditions but not the mountainous seas on the day I left.

This week ... looks like a predominantly cloudy period to start the week and this could bring rain at times. Midweek should be better with less showers but the cloudy conditions could return at the end of the week. Yes, this is the rain streamers that I have mentioned earlier.

To demonstrate, all you have to do is look up at the clouds and, if you see different layers of cloud moving in completely different directions then you are looking at the trades going one way (normally west) and the streamers going another way (north west, north, north east or east). When you see this there is a good chance of rain.

The sea is moderate but there are signs that it could get a little heavier towards the end of the week.

Enjoy ...
