Saint Lucia is located in Central America. The country is washed by the Caribbean Sea. Saint Lucia is a small country. To determine the temperature of the water in it, we monitor only one locality.

The climate of the island is tropical trade winds, warm and fairly even. The average monthly temperature in the winter period (December-March) fluctuates around the mark of +24 o C, in the summer - about +26 o C. Moreover, the daily temperature differences are small, even in winter the difference between night and day does not exceed 6 degrees. The water temperature off the coast all year round is about + 24-26 o C. Precipitation is about 1300 mm per year. Two seasons are quite clearly distinguished: dry (from January to March-April) and rainy (from May-June to September-December). Powerful but short-term heavy rains, usually at the end of the day, are possible at any time of the year. Destructive tropical hurricanes are frequent, especially frequent at the end of summer.
