The Meteorological Office has said the minimum temperature at Piarco during the pre-dawn hours of Tuesday was 19 degrees Celsius, a record-breaking low temperature.
This was the lowest temperature recorded at Piarco since 2011.
In a release, it said this was due to colder air from the north encroaching onto Trinidad and Tobago in conditions where the winds were mostly calm, with pre-existing very dry conditions, and almost cloud-free skies for most of the night.
The Met Office said the last time a temperature of 19 degrees was recorded was in January 2010.
It added, “But it is not uncommon for January to produce minimum temperatures below 20 degrees Celsius. The lowest minimum temperature on record is at Piarco is 16.1 degrees Celsius, recorded in January 1964, followed by 16.4 degrees Celsius in January 1976.”
The release said in general, the coldest given night in TT depends on individual weather systems present at a particular time, but is usually based on a seasonal cycle, where on average the coldest nights occur during December to February.
It said it is for this and other reasons that the Met Office’s 2021 dry season rainfall and temperature outlook indicated “few nights during January and February are likely to be relatively cold with minimum temperatures falling below 20 degrees Celsius.”
