St Lucia Weather
St Lucia is a volcanic island which has lush rainforests and cooling breezes, thanks to its location in the Eastern Caribbean where it meets the Atlantic Ocean. More mountainous than other Caribbean islands, St Lucia enjoys a tropical climate and is at its driest between December and March. This is the most popular time to visit. The northeast tradewinds provide a constant cooling effect. The mountainous nature of St Lucia means that rainfall can be heavier over other smaller islands nearby.
Situated in the hurricane belt, the hurricane season runs between June and October. This is by far the most significant feature of St Lucia weather. Although severe storms are rare, directly affecting the area approximately once every 19.71 years, St Lucia has been affected by them in the past. 1780 saw the deadliest Atlantic Hurricane season ever, with a hurricane practically destroying Soufriere – the capital at the time and another storm causing severe damage across St Lucia.
Soufriere has been the victim of hurricane damage several times during its history, being hit again in 1817, 1831, and 1898. 1960 saw Hurricane Abby hit with 80mph winds which killed 6 people, 1963 Hurricane Edith killed 10, Hurricane Debby hit in 1994, destroying 60% of the banana crop. St Lucia was most recently hit by Hurricane Dean in 2007. This hurricane was so powerful that it blew the roof off of the children’s ward at Victoria Hospital and blew wave breaking boulders onto the highway. This is testimony to the fact that St Lucia weather can be very turbulent, although having said that, the island does not suffer anything like as regularly as some other parts of the Caribbean.
Hurricane Allen occurred in 1980, causing wide spread damage estimated at $235 million. Predictions estimate that the next hurricane to hit St Lucia will occur around 2011.
In January, the average high temperature is 81 Fahrenheit (around 27.5 Celsius), with the average low 68 Fahrenheit (20 degrees Celsius). In July the high is 85 Fahrenheit (29.5 Celsius) and the low is 72 Fahrenheit (22 Celsius). These statistics show that the St Lucia weather is very similar throughout the year. Humidity is between 76% to 83%. The St Lucia weather is generally lovely all year round, although sporadic showers can occur during the summer. These can be quite welcome though, and the locals refer to them as “liquid sunshine”.
Meteorological records show that the lowest temperatures ever recorded on the island were 13.3 Celsius (57 Fahrenheit) in Soufriere, 15.6 (60 Fahrenheit) in Castries, and 17.4 (64 Fahrenheit) at Hewanorra Airport. The highest recorded temperatures in the same locations were 36.1 Celsius, 35.6 Celsius, and 33.1 Celsius respectively.
St Lucia generally enjoys between 7 and 9 hours of sunshine a day depending on the time of year. Water temperatures range between 79 and 84 degrees Fahrenheit. The average annual rainfall is 60 inches.
Weather statistics show that St Lucia is wetter in general throughout the year than Barbados, this being due to its higher mountains.
The St Lucia weather is monitored and forecast by the St Lucia Meteorological Service. They have two weather stations, one in the north of St Lucia and the other in the south.
The main thing you need to know about the St Lucia weather is the fact that you are pretty much guaranteed plenty of sunshine and sub-tropical temperatures all year round. If you prefer the St Lucia weather to be a little more cooling, head inland to the rain forest where you will often be provided with a welcome shower.
