Summary of Expected conditions:

From 16^th to 30^th April 2026, near- to above-normal rainfall with wet days (23^rd , 24^th, 25^th and 26^th) are expected to maintain soil moisture and reduce vegetation browning across farmlands. Although very warm at times, there is a low risk of heat-related hazards. 

Weather Assessment for the period 1^st to 15^th April 2026.

Across north-central Trinidad and Piarco, moistened soil and less vegetation browning was noticed across various farmlands. Borderline dry conditions at the end of March eased temporarily by the 15th April. Although the drying trend has continued across Tobago early April, there is no concern of agricultural drought so far, TTMS Dryness/Drought Monitor and Outlook.  

Rainfall: 

During the 15 days, Trinidad has experienced much above normal rainfall. At Piarco,  61.4 mm was recorded from two wet days (with ≥ 10 mm) and two relatively wet days (with ≥ 1 mm). The highest daily total recorded was 40.2 mm (4^th ) followed by 13.2 mm (5^th). Tobago meanwhile has experienced much below normal up to the 15^th April. Crown Point received 10.7 mm from five relatively wet days (with ≥ 1 mm) . The rainfall totals maps for the period 1^st to 15^th  April for Trinidad and Tobago are located below as figure 1 and figure 2.

Temperatures:

For the first half of April 2026, no hot days/spells were observed at either Piarco (maximum temperature at least 34.0 ⁰C) or Crown Point (maximum temperature at least 33.0 ⁰C). Mainly near normal daytime temperatures have prevailed at Piarco with the highest maximum daytime temperature 32.9 ⁰C (2^nd) with a ‘real feel’ of 36 ⁰C. Crown Point has also observed near normal daytime temperatures with a maximum daytime temperature 31.4 ⁰C (15^th). Factoring the relative humidity however these temperatures have a ‘real feel’ that is higher than the observed maximum temperature.

From 1^st to 15^th of April, nighttime temperatures were mainly above-normal. The 11^th was the warmest night over the 15 days, 24.9 ⁰C  at Piarco and 26.3 °C at Crown Point.

Tobago Rainfall Forecast for the 15-Day period of  April (16^th to 30^th) 2026.

Figure 4.    Rainfall map of Tobago showing expected mean rainfall totals for districts across Tobago during the 15-day period (16^th to 30^th April 2026) and percentage probability of occurrence.

North-Eastern areas: High chance (75%) of mean daily rainfall up to 3.0 mm.

South-Western areas: High chance (75%) of mean daily rainfall up to 2.6 mm.

Trinidad and Tobago:

There is a moderate (60-70%) chance of near- to above-normal rainfall 16^th to 30^th April 2026. The weather across most farmlands during this period will feature occasional light to moderate rainfall and mostly cloudy skies. Wet days with heavy showers and thunderstorms are mainly expected 23^rd to 26^th April.

The forecast rainfall totals (16-30^th) across most farmlands will range between 31 mm and 79 mm in Trinidad, see figure 3, and between 36 mm and 47 mm in Tobago, see figure 4. However, isolated higher amounts up to 117mm are possible on upslope fields and along windward coasts. 

There is a greater potential for cloudiness and precipitation/convection over the Guianas and Lesser Antilles despite bouts of dry Saharan dust/air during the period. Weaker than average surface winds present near the Guianas will cause upwelling of moist air across Trinidad and Tobago. 

Temperatures & Winds:

There is a low risk of heat-related hazards across most of Trinidad and Tobago. Mainly warm conditions are expected nationwide with moderate (30-40%) chance of above normal daytime temperatures and a moderate (60%) chance of above normal nighttime temperatures. However western Trinidad has a moderate (30%) chance of three consecutive very warm days (33 °C) mainly towards the end of April. 

Generally daily maximum temperatures of 30-32 °C are expected, but up to 33 °C in western Trinidad which could reach 34 °C in urban centres. When factoring humidity on the hottest days however, daytime conditions would feel as hot as 34°C to 38 °C in Trinidad. Generally nighttime minimum temperatures will range from 22 °C to 24 °C however cooler nights of 21°C are possible in elevated/sheltered valleys such as Paramin, Upper Maracas, Lopinot, Runnemede and Main Ridge. 

Moderate winds generally from the east are expected, however, fresh to strong gusts are likely near hilltops and exposed eastern coastal areas. Average daily evaporation rates of 6.0 are expected but faster water loss is expected during very warm and breezy days during the period. 

Moisture levels:

Daytime relative humidity levels are expected to range from the high-40s to high-70s in terms of percentage, with a peak of 80% on wet days, leading to occasional muggy conditions in western areas, particularly in the afternoons and evenings. 

Highlighted Possible Impacts on Agriculture:

From 16th to 30th April 2026, near- to above-normal rainfall and wet days (23rd , 24th, 25th and 26th) are expected to maintain soil moisture and reduce vegetation browning across farmlands. Favorable weather conditions for agricultural activities are expected. Although very warm, there is a low risk of heat-related hazards for farm workers, young livestock, newly germinated/ transplanted seedlings onto fields. 

Breezy conditions may  possibly damage young plants and flowering mature plants on exposed hillsides. Moist conditions may develop however in wind-sheltered areas. When humidity is too high over crop beds, a higher risk of fungal, bacterial and viral infections exists.

During the odd heavy shower the risk of street/flash flooding increases, however, land slippage is not expected. Plumes of Saharan dust/air may significantly affect small ruminants and poultry. 

Maintain wind-breaks and irrigate crops as needed especially in the flowering stage. Ensure regular weeding to reduce competition and water stress on crops. Implement pest and disease control measures as recommended. 

Sun and Moon Positions in the Sky April (16^th to 30^th) 2026.

On the 16^th April, the sun is directly overhead at latitude 10.3° degrees North of the Equator. The day-length or number of sunlight hours in Trinidad and Tobago on the 16^th will be 12 hours, 22 minutes increasing to 12 hours, 30 minutes on the 30^th April 2026.

Moon Phases: New Moon, 17^th and First Quarter, 23^rd. According to the tradition of moon phases: April 18^th – 19^th, 22^nd – 23^rd are good days for planting above -ground crops; April 28^th - 30^th are good days for planting below-ground crops. Remaining days are poor planting days and useful for removing weeds, clearing land and ploughing fields.
