Summary of Expected conditions:

From 1^st to 15^th April 2026, below-normal rainfall amounts are expected to lower soil moisture, increase vegetation browning and bush fire risk across farmlands, alongside an increasing risk of heat-related hazards towards mid-April. 

Weather Assessment for the period 16^th to 31^st March 2026.

Scanty rainfall for the past 14 days across many farmlands has continued the drying trend mid-to-late March, leading to vegetation browning and increased risk/potential for bush fires. 

Rainfall: 

Scanty rainfall from the 16^th to 31^st March has led to both islands experiencing much below normal rainfall. Piarco had a 15-day rainfall total of 6.9 mm from two relatively wet days. Meanwhile Tobago, at Crown Point received 13.9 mm from three relatively wet days. 

The rainfall totals maps for the period 16^th to 31^st March for Trinidad and Tobago are located below as figure 1 and figure 2.

Temperatures:

During the second half of March 2026, no hot days or 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 prevailed at Piarco with one very warm day of maximum daytime temperature 33.3 ⁰C (23^rd). Crown Point observed near to above normal daytime temperatures with a maximum daytime temperature 31.2 ⁰C (25^th). Factoring the relative humidity however these temperatures had a ‘real feel’ that was higher than the observed maximum temperature.

From 16^th to 31^st of March, nighttime temperatures were mainly above-normal in Trinidad, reaching a warm 24.7 ⁰C (12^th) at Piarco and at Crown Point, 25.0 °C (24^th, 29^th). However, a week later, cooler than normal nights (20^th - 22^nd) and the coldest nights of 2026 were experienced at both Piarco (20.0 ⁰C, 22^nd) and Crown Point ( 21.8 ⁰C, 22^nd) as a frontal system swept colder air across the islands leading to dense fog patches.

South-Western areas: Moderate chance (60%) of mean daily rainfall up to 2.0 mm.

Trinidad and Tobago:

Weather conditions from 1^st to 15^th April for most farmlands are expected to be predominantly breezy, very warm and dry. Relatively wet days with light to moderate showers with an isolated heavy shower are expected however, bouts of Saharan dust/air and breezy/windy conditions will limit rain cloud formation during the period. 

Below-normal rainfall amounts are expected from 1^st to 15^th April 2026. During the first week, 1^st to 7^th April, there is a low to moderate (10-40%) chance of near normal rainfall amounts. The second week 8^th to 15^th however, has a moderate to high (40-80%) chance of below-normal rainfall. During the 15-day period, 1^st to 15^th, forecast rainfall totals in Trinidad are expected to generally range between 22 mm and 61 mm, see figure 3. In Tobago, the 15-day forecast rainfall is expected to range between 28 mm and 41 mm favouring farmlands on hillsides and windward coasts, see figure 4. 

Temperatures & Winds:

There is an increasing risk of heat-related hazards towards mid-April 2026. From 1^st to 7^thApril, both islands can expect warm days. From 8^th to 15^th April, very warm days are forecast with a couple of hot days favouring Trinidad. Generally daily maximum temperatures of 32-33 °C are expected however, farmlands near urban areas could experience as high as 34 °C leading to daytime conditions feeling as hot as 40 °C, when factoring humidity on the hottest days. Generally nighttime minimum temperatures will be 21-23 °C however cooler nights of 21°C are possible in elevated/sheltered valleys such as Paramin, Upper Maracas, Lopinot, Runnemede and Main Ridge. During the 15-day period, 1^st to 16^th April 2026, there is a moderate (40%) chance of above normal daytime temperatures and a moderate (60%) chance of above normal nighttime temperatures. 

Winds, generally east to northeast, with above normal strength 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/windy days during the period. 

Moisture levels:

Low to moderate daytime relative humidity levels are expected from the mid-50s to high-70s in terms of percentage, but may rise to a peak of 85%, leading to occasional muggy conditions in western areas, particularly in the afternoons and evenings. 

Highlighted Possible Impacts on Agriculture:

The first two weeks in April are expected to be drier and windier than normal, lowering soil moisture, increasing vegetation browning and bush fire risk across farmlands. Breezy/windy conditions will possibly damage young plants and flowering mature plants on exposed hillsides. Despite breezy/windy conditions, moist conditions may develop in wind-sheltered areas and provide a moderate chance for fungal spread, insect pests and diseases to develop in crop beds. Mainly light to moderate showers anticipated early-to-mid April should ensure a low risk of street/flash flooding or land slippage on fields and access roads. There is an increasing risk of heat-related hazards for farm workers, young livestock, newly germinated/ transplanted seedlings onto fields. Plumes of Saharan dust/air may significantly affect small ruminants and poultry. 

Favorable weather conditions for agricultural activities are expected. 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 (1^st to 15^th) 2026.

The sun is presently at latitude 4.7° degrees North of the Equator. The day-length or number of sunlight hours in Trinidad and Tobago from April 1^st will be 12 hours, 14 minutes increasing to 12 hours, 22 minutes on April 15^th 2026.

Moon Phases: Full Moon, 1^st and Third Quarter, 10^th. According to the tradition of moon phases: April 1^st – 3^rd, 9^th – 10^th, 13^th – 15^th are good days for planting below-ground crops; April 4^th - 5^th, 13^th - 15^th are good days for planting above-ground crops. Remaining days are poor planting days and useful for removing weeds, clearing land and ploughing fields.
