Visitors to St. Lucia should be aware that there can be a great deal of variation in weather between the different regions of St. Lucia. If you are visiting one of the beaches around Castries or Rodney Bay, expect temperatures to be high but not unbearable due to the cool breeze off the water. Visitors exploring one of the trails through the rain forest in the center of the island need to be prepared for some very hot and humid weather without any relief from the winds. Adventurous travelers can cool off on a hike to one of the Piton mountains, the distinguishing landscape feature of St. Lucia. Temperatures will drop significantly as the altitude increases and travelers may even want to bring along a light jacket to stay comfortable in the cool weather.
