Yellow

Hot Spell Alert #1 -Yellow Level

Effective: Thursday, September 24, 2026 - 2:00 PM
Expires: Saturday, October 31, 2026 - 4:00 PM
The months of September and October represent the final two months of Trinidad and Tobago’s heat season. During this period, conditions remain favourable for episodes of elevated temperatures and the occurrence of Hot Spells.
The Trinidad and Tobago Meteorological Service (TTMS) defines a Hot Spell as a period of at least five consecutive days during which maximum temperatures meet or exceed 34.0 °C in Trinidad and 33.0 °C in Tobago.
For the remainder of September and into October 2026, there remains the potential for Hot Spell conditions. Over the coming weeks, maximum daytime temperatures are expected to reach around 34.0 °C or higher in Trinidad and around 33.0 °C or higher in Tobago, particularly during periods of reduced cloud cover and rainfall.
The hottest period of the day is generally between 10:00 a.m. and 4:00 p.m. During this period, temperatures are expected to be higher in urban, built-up and densely developed areas, where the urban heat island effect can further increase daytime temperatures. Consequently, “feels-like” temperatures may range from approximately 34.0 °C to 44.0 °C, depending on the location, humidity, wind conditions and degree of urbanization.
The prevailing large-scale atmospheric and oceanic conditions are also expected to support periods of reduced rainfall and cloud development. El Niño-related influences, where applicable, can contribute to warmer and drier conditions by suppressing convection and reducing daytime cloud development. Reduced cloud cover allows greater solar heating of the land surface, resulting in higher daytime temperatures and, in combination with elevated humidity, increased heat stress.
Although rainfall events associated with tropical waves, the Inter-Tropical Convergence Zone (ITCZ), or other weather systems may occur during the remainder of the heat season, these events are not expected to provide a sustained break from the prevailing heat. Where rainfall occurs, it may provide temporary relief, with hot conditions potentially returning as cloud cover and rainfall decrease.
