The most popular tourist times to visit Trinidad & Tobago are for the country’s famous Carnival (Mardi Gras) which takes place annually the Tuesday before Ash Wednesday and airfares reflect this, so book early. Christmas and summertime travel are popular among expats returning home and so airfares tend to be on the high side then as well. Travelers who can visit T&T during other times of the year will find that they may be lucky enough to find round-trip tickets at much lower prices.
Trinidad & Tobago is, happily, out of the hurricane belt and rarely do large storms hit the islands. Occasionally there are earthquakes, and local lore often correlates the seismic events to periods of uncharacteristic heat. Temperatures in Trinidad & Tobago do not fluctuate widely and tend to be around 85 degrees Fahrenheit, inching closer to 90 degrees during the summer. There is little seasonal change with the notable exception of the rainy season, which is June to December. The dry season from January to May is an ideal time to visit, but brushfires during this time of year are not uncommon.
