Re: February weather St. Lucia Jul 28, 2009, 10:53 PM February is definitely a good time to go to St. Lucia,as you typically have low amount of rainfall during that month. The average temperature should be about 80-85 degrees. If it happens to rain, then you usually get 10 minute showers during the day and after that the sun comes out again.
The average temperature on St. Lucia ranges from 70 degrees Fahrenheit to the upper 90s. Humidity on the island averages between 70 and 90 percent throughout the year. December through January are generally the coolest months with the temperatures being in the mid 70s to mid 80s in degrees Fahrenheit.
