April 2020 – Warmest April On Record In The Caribbean

April 2020 was the hottest April on record for the Caribbean Region and second hottest globally, according to the National Centers for Environmental Information, a division of the United States National Oceanic and Atmospheric Administration (NOAA).

Averaged as a whole, the global land and ocean surface temperature for April 2020 was 1.06°C (1.91°F) above the 20th century average of 13.7°C (56.7°F) and the second-highest in the 141-year record. Only April 2016 was warmer at 1.13°C (2.03°F) in NOAA’s 141-year global temperature dataset record, dating back to 1880.

The April 2020 value is also tied with December 2019 as the 11th highest monthly temperature departure in the 1,684-monthly record. April 2020 also marked the 44th consecutive April and the 424th consecutive month with temperatures, at least nominally, above the 20th-century average.

In the Caribbean, based on NOAA’s data, the region had its warmest April on record at 1.11°C (2.00°F) above average. This was the first time the Caribbean region had a temperature departure over 1.0°C (1.8°F) during the month of April. This was also the Caribbean’s sixth-highest monthly (tied with August 2016) temperature departure in the 1,336-monthly regional record.

In the Trinidad and Tobago Meteorological Service’s preliminary assessment of the 2020 Dry Season at the end of April 2020, maximum temperatures at Piarco reached as high as, or above, 34.0°C on three days, including the warmest 2020 dry season maximum temperature (so far) of 34.3°C which occurred on Monday 27th, April.

Notably, maximum temperatures reached or exceeded 33.0°C on 20 days of the month. Temperatures in Tobago were not as warm, as the highest maximum temperatures climbed above 32.0°C on three days to peak at 32.8°C on April 19th.

In Trinidad and Tobago, we also experienced much drier than usual conditions, with precipitation coming in between 0% to 25% of our long-term-averages, between a 40 and 60-millimeter deficit.

In fact, according to the Trinidad and Tobago Meteorological Service, Trinidad recorded its second driest April on record, coming second only to April 1947. This follows from the 12th driest March on record.

April is generally our third driest month in Trinidad and Tobago for the year, following March then February, with an average precipitation total of 59 millimeters at Piarco according to the Trinidad and Tobago Meteorological Service.

Much of the Eastern Caribbean also recorded similar deficits, with northeastern South America seeing lower overall precipitation.
