The climate in Trinidad and Tobago

Climate zone: tropics

High humidity and hot temperatures make the weather in Trinidad and Tobago pleasant at times but also tropical humid. It is warm to hot all year round, inviting bathing at average water temperatures of 28 degrees. Due to less rain, the best time for traveling is from February to May. Most precipitation falls from June to November.

Temperature records of the last 47 years

The hottest temperature measured from 1969 to November 2016 was reported by the Crown Point weather station. In November 2016, the record temperature of 32.4 °C was reported here. The hottest summer from July to September was recorded in 1998 with an average temperature of 28.3 °C. This average temperature will normally be measured every four to six hours, thus also including the nights. Normally, this value is 27.6 degrees Celsius. The average maximum daily temperature at that time was 31.7 °C.

The coldest day in these 47 years was reported by the Crown Point weather station. Here the temperature dropped to 21.4 °C in February 1999. Crown Point lies at an altitude of six meters above sea level. The coldest winter (January to March) was in 1983 with an average temperature of 25.9 °C. In Trinidad and Tobago, it is usual to have about 0.8 degrees more at 26.6 °C for this three-month period.

The most precipitation fell in April 1982. With 14.9 mm per day, the Crown Point weather station recorded the highest monthly average of the last 47 years.

Long-term development of temperatures from 1990 - 2021

In contrast to single record values, long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. An average value would give a distorted result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and distorts the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have comparable data over as long a period as possible.

In the years 1990 to 2021, there were only these 1 weather stations in the whole country, which reported continuous temperature values (Piarco). From these weather reports, we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was April 2010 at 28.9 °C. January 1992 was the coldest month with an average temperature of 24.8 °C.

The average annual temperature was about 26.4 °C in the years after 1990 and about 26.9 °C in the last years before 2021. It has therefore increased only slightly by about 0.5 °C over the past 32 years. This trend only applies to the selected 1 weather stations in Trinidad and Tobago. A considerably more comprehensive evaluation of global warming has been provided separately.
