Though the South Pacific Islands are warm all year round, there are varying degrees of wet and dry weather. This will impact when you want to travel depending on what you prefer. As trade winds blow through the region they bring moderate tropical weather from May to October. Wet seasons come in November and last through to April. Tropical storms are common, as are days of rainy weather, punctuated by periods of high-humidity sunshine. Temperatures are cooler farther from the equator. Plus you will experience slightly more varied weather patterns throughout the seasons. If you're more concerned about crowds than weather, you may want to avoid July and August when rates are higher and tourist traffic is at the max.
