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.

Hi Paul

Thanks for the kind words and glad you like it. I am still frantically trying to sort all the updates from Tobago business owners, following our 'soft' release at the end of last week. Various technical tweaks to make - and then a full public announcement at the end of this week or thereabouts. In the meantime, keep up the good work yourself.

Hurricane Forecast

The Atlantic tropics have died down as expected but there is a little disturbance in the Inter-Tropical Convergence Zone (ITCZ) about 900 miles east of Tobago. The NHC are issuing advisories but only rates development chances at 10%.

The ITCZ is currently rather lively and at this time of year, the earth's tilt has the ITCZ spanning around the zero degree (equator) point which means that Tobago is just 10 degrees north of the ITCZ. It is rare for storms to develop from the ITCZ, so I am not getting excited about the new disturbance but the unsettled weather for Tobago could continue for longer than I predicted in last Sunday's Liquid Sunshine post.

Former Hurricane Florence's remnants have emerged off the north east coast of the US and Canada and there seems to be a chance of further development but, as yet, nothing of concern.

Former Hurricane Helene proved not to be the storm the UK Met Office expected and the warnings were cancelled on Thursday morning, however there was a very warm breeze. This warm air probably energized Storm Ali that hit the UK today quite hard and brought several fatalities. The UK Met Office predicted this perfectly and there are more storms to come for the UK over the next week. The Dahlias are all standing to attention although the hanging baskets had to be brought down.

I don't expect anything significant in the tropical Atlantic for a couple of weeks but the energy is building, particularly in the western Caribbean and the Gulf of Mexico ... for now I would watch the ITCZ because this can produce a rain event for Tobago and around the south and south east Caribbean ... the risks of this are quite high over the next 7 to 10 days.
