Untouched forests, pristine white sand beaches, crystal waters filled with reefs and diverse sea life: a South Pacific cruise offers the ultimate getaway from winters in both the northern and southern hemispheres. Tropical climates mean the islands of the South Pacific experience warm, humid weather, with temperatures hovering around 75 degrees Fahrenheit year round. Although humidity is a constant, even temperatures and fresh sea breezes ensure that conditions are never too stuffy. That said, many travelers consider the dry season, from May through October, the ideal time to cruise between the South Pacific islands. The winter trade winds that blow steadily during this time bring delightful temperature averaging between the upper 70's to lower 80's (degrees Fahrenheit) daily.

The austral summer, occurring from November to April, is the warmer and more humid wet season, and is characterized with heavy rainstorms interspersed with extreme sunshine. It is also important to keep in mind that tropical storm season is within the wet season, from November to March.

While the coastal temperatures remain balmy, remember that as you climb in elevation, temperatures drop. If you're planning an excursion up into the mountains, be prepared for chillier temperatures. Due to the influence of the traditional July-August holiday season in Europe, these months also are the busiest tourist season in the South Pacific, as well as school holidays and late December through January. If crowd avoidance is important, plan your South Pacific cruise outside these busier times.
