The St. Vincent and the Grenadines Meteorological Services has issued a 72-hour weather outlook as of July 22, 2026, detailing a series of weather events set to impact the islands over the coming days. While a ridge pattern has maintained relatively fair conditions recently, a shift toward more active weather is imminent with the arrival of two tropical waves and a Saharan dust event.
Forecaster Gregory Cato noted that the first tropical wave is expected to bring increased cloudiness and showers starting Thursday evening. Residents can expect Thursday to be partly cloudy and breezy at times, with slightly hazy conditions before the weather begins to turn later in the day.
By Friday, July 24, the focus will shift to a weather advisory concerning Saharan dust haze. Moderate concentrations of dust are expected to move across the region, which will likely reduce air quality and visibility. Authorities have advised the public to take necessary precautions during this period. Friday’s forecast includes occasionally cloudy and hazy skies with scattered showers and breezy conditions.
A second, more significant tropical wave is scheduled to affect the islands on Saturday, July 25. This system is forecast to be aided by a supportive upper-level environment, which increases the possibility of thunderstorms in addition to cloudy periods and scattered showers.
Winds are currently blowing from the east south east to the east at speeds of 20 to 30 kilometers per hour. These trade winds may increase to 35 kilometers per hour on Thursday and Friday, with a temporary shift toward the east north east expected on Friday. Wind speeds are projected to decrease to between 15 and 25 kilometers per hour by Saturday.
For those venturing out to sea, conditions are predicted to remain slight to moderate in open water with no marine advisories currently active. Swell heights are expected to reach approximately 1.0 meter on the western coasts and 1.5 meters on the eastern coasts throughout the period.
