ISSUED AT: 12:37 PM
Date: Wednesday 1st of February 2023

Summary:
Low rainfall amounts are expected during the fifteen days.
Eight relatively wet days with rainfall amounts less than 5.0 mm are expected on the 4th-7th, 10th, 12th-14th of February, while seven relatively dry days with rainfall amounts less than 1.0 mm are expected on 1st-3rd, 8th-9th, 11th and 15th February 2023.
Trinidad and Tobago:
Eight relatively wet days with rainfall amounts less than 5.0 mm are expected on the 4th-7th, 10th, 12th-14th of December, while seven relatively dry days with rainfall amounts less than 1.0 mm are expected on the 1st-3rd, 8th-9th, 11th and 15th February 2023. The daily rainfall totals are forecast to range between 0.0 mm to 5.0 mm across different farmlands, with fifteen-day rainfall totals ranging between 25.0 mm and 50.0 mm. The impactful rainfall events will mostly occur across the eastern, parts of Trinidad and south eastern Tobago.
Temperatures & Winds:
The maximum temperatures are expected to remain warm, with temperatures ranging between 30.0oC to 31.5oC throughout the period. However, temperatures are expected to have a real-feel or feels-like between 30.0oC to 33.0oC on most days. The minimum temperatures will range between 19.5oC to 23.0oC during most nights/early mornings, dropping lower in rural areas and valleys.
Mostly weak to moderate north-easterly to easterly winds of an average speed of 20-25 km/h are expected, with gusts of 30-35 km/h at times. Low rainfall totals, low to moderate wind speeds, cool to warm days and warm feels-like temperatures will sustain average evapotranspiration rates in crops ranging between 5.0 to 9.0 millimeters per day.
Moisture levels:
Over the fifteen-day period across Trinidad and Tobago, moisture levels are expected to be moderate to high, with average daytime relative humidity values in the upper-40s to lower-80s, in terms of percentage.
Highlighted Possible Impacts on Agriculture:
During this first 15-day forecast period of (1st to 15th) February 2023, expect similar conditions to occur as compared to the third 15-day (21st to 04th) January/February forecast period. There is a moderate probability (50%) chance for crop irrigation measures to take place owing to the drying out of soils during the forecast period. There is also a low probability (20%) chance for fungi spread, root and/or fruit rot, insect pests and warm weather diseases to develop in crop beds. River levels will remain at low levels during this forecast period.

Sun and Moon Positions in the Sky February (1st – 15th) 2023.
The sun is presently at 17.0 degrees South latitude and with this position, the day-length or number of sunlight hours in Trinidad and Tobago from February 1st will be 11 hours and 41 minutes, rising slightly to 11 hours and 48 minutes by 15th February 2023. According to the moon’s phases, the 1st-3rd and 15th of February are good days for planting aboveground crops, while 9th-12th and 15th are good days to plant below ground crops. However 4th, 5th (Full Moon Phase), 7th-8th and 13th (Third Quarter Phase)-14th are poor planting days. These days should be used for removing weeds, clearing land and ploughing fields.
Weather Assessment for the period December (21st – 31st) 2023.
