Temperatures:

Trinidad and Tobago is in its cool season (northern hemisphere winter months of December to February). During the second half of December, there were no hot days at Piarco (maximum temperature at least 34.0 ⁰C) with a maximum daytime temperature reached 31.8 ⁰C  both the 17^th and 26^th. The nighttime conditions have cooled, night-time minimum temperatures fell as low as 22.4 ⁰C at Piarco. 

Similarly, Crown Point, Tobago did not observe any hot days (maximum temperatures at least 33.0 ⁰C) the maximum daytime temperature reached 30.8 ⁰C (22^nd) and the minimum temperatures fell to 22.3 ⁰C at Crown Point.

Factoring in the relative humidity, however these temperatures had a ‘real feel’ that was higher than the observed maximum temperature.

South-Western areas: Moderate chance (68%) of mean daily rainfall up to 2.5 mm.

Trinidad and Tobago:

From January 1st to 15th, mainly patchy cloudiness to partly cloudy periods and breezy conditions with occasional showers are expected to produce near-normal rainfall amounts across farmlands. Near normal rainfall amounts are expected across various farmlands from January 1^st to 15^th with relatively wet days forecast on the 6^th and 10^th and a wet day on the 9^th January 2026. On wet days, there is a low to moderate risk of street/ flash flooding on low-lying and access roads. The rainfall totals in Trinidad are expected to range between 25 mm and 60 mm favoring the southern, eastern and northeastern areas of Trinidad, see figure 3. In Tobago, the rainfall is expected to be around 38 mm favouring farmlands across all of Tobago., see figure 4. 

Temperatures & Winds:

There is a very low (10%) risk of heat hazards in January 2026. Daily maximum temperatures of 28 °C to 30 °C are forecast, however temperatures are expected to feel as hot as 30 °C to 35 °C when factoring humidity on the hottest days and calm winds. Generally nighttime minimum temperatures will range from 22 °C to 24 °C.

Generally steady, moderate to fresh east to northeasterly winds at near normal wind speeds are expected with a moderate (65%) chance of occasional gusts of 30 km/h or higher on hilltops and exposed coastal areas. Evaporation rates up to 5.0 mm per day on average are expected, especially on warm, breezy days forecast during the period. 

Moisture levels:

Low to moderate moisture levels are expected across Trinidad and Tobago over the fifteen-day period, with average daytime relative humidity values expected from the mid-50s to low-90s, in terms of percentage.

Highlighted Possible Impacts on Agriculture:

From the 1^st to 15^th, there is a very low (10%) risk of heat hazards for farm workers, young livestock, newly germinated/ transplanted seedlings onto fields. Warm but less moist conditions will provide a low (20%) chance for fungal spread, insect pests and diseases to develop in crop beds. Saharan dust/air may affect small ruminants and poultry.

There is a low to moderate risk of street/flash flooding, on access roads. Downpours producing strong gusts will likely damage young plants and flowering mature plants in exposed hilly areas.  Maintain adequate drainage on fields. Ensure regular weeding to reduce competition and water stress on crops. Implement pest and disease control measures as recommended. Monitor crops and irrigate crops as needed especially in the flowering stage.

Sun and Moon Positions in the Sky December (1^st  to 15^th) 2026.

The sun is presently at latitude 23.1° degrees South of the Equator. The day-length or number of sunlight hours in Trinidad and Tobago from January 1^st will be 11 hours, 31 minutes, increasing to 11 hours, 34 minutes on January 15^th 2026.

Moon Phases: Full  Moon, 3^rd and Third Quarter, 10^th. According to the tradition of moon phases: January 1^st, 2^nd , 14^th, and 15^th are bad days for planting crops; The 3^rd-4^th and 9^th-13^th are good days for planting root crops while the 5^th-8^th are barren days best for killing weeds, clearing land, and ploughing fields.
