On Sep­tem­ber 14th, Trinidad record­ed its high­est tem­per­a­ture for 2020 to date, a scorch­ing 34.8°C at Pi­ar­co.  Over the last four days, Trinidad’s max­i­mum highs at Pi­ar­co have not re­lent­ed be­low the 34°C mark.

Sep­tem­ber to Oc­to­ber is the warmest pe­ri­od of the sec­ond half of the lo­cal heat sea­son, with Sep­tem­ber typ­i­cal­ly the hottest month, ac­cord­ing to the Trinidad and To­ba­go Me­te­o­ro­log­i­cal Ser­vice (TTMS).

In their “Rain­fall and Tem­per­a­ture Out­look for Trinidad and To­ba­go, Sep­tem­ber to No­vem­ber 2020,” the TTMS is call­ing for a 72% chance for an above-av­er­age day max­i­mum and night min­i­mum tem­per­a­tures for Trinidad and To­ba­go through the out­look pe­ri­od.

“Warmer than usu­al days and nights are ex­pect­ed dur­ing Sep­tem­ber, Oc­to­ber, and No­vem­ber 2020 with day-time and night-time tem­per­a­tures very like­ly to be warmer than av­er­age,” the Met Ser­vice says.

Con­cerns for an in­crease in the num­ber of hot days and short du­ra­tion hot spells re­main el­e­vat­ed for Sep­tem­ber and ear­ly Oc­to­ber.  The TTMS de­fines a hot day as one where max­i­mum tem­per­a­tures greater than 33.9°C in Trinidad and greater than 32°C in To­ba­go, oc­cur.  Al­so, the con­cern for an in­creased num­ber of hot days and warm nights are high­er in cities and ur­ban ar­eas, such as Port of Spain and Ch­agua­nas.

High­er than usu­al and ex­treme tem­per­a­tures can lead to rel­a­tive­ly ex­ces­sive heat dur­ing the peak of the lo­cal heat sea­son, which can am­pli­fy ex­ist­ing health con­di­tions in vul­ner­a­ble per­sons, and wors­en chron­ic health con­di­tions in oth­ers. Sev­er­al days be­tween Sep­tem­ber and Oc­to­ber are like­ly to feel un­com­fort­able due to high tem­per­a­tures and high hu­mid­i­ty val­ues.

These high tem­per­a­tures are on the heels of a record-warm Au­gust 2020 for Trinidad and To­ba­go. The coun­try tied for the sixth warmest Au­gust on record, with tem­per­a­tures go­ing back 76 years at Pi­ar­co. Ac­cord­ing to the TTMS’ Pre­lim­i­nary Cli­mate Overview, both is­lands ex­pe­ri­enced a warmer than av­er­age Au­gust 2020.

The TTMS record­ed one hot spell be­tween Au­gust 24th and Au­gust 28th, where Trinidad record­ed max­i­mum high tem­per­a­tures at or above 34.0°C. How­ev­er, the TTMS not­ed that the month’s high­est record­ed tem­per­a­ture oc­curred on Au­gust 15th, out­side of the brief heat­wave.

To­ba­go al­so record­ed sev­er­al hot days, with the max­i­mum high­est tem­per­a­ture record­ed on the is­land at 33.4°C on Au­gust 27th. The oth­er hottest day oc­curred on Au­gust 10th, with a max­i­mum high of 33.0°C.
