Fiji is a year-round destination due to its more than 330 islands and tropical climate. In Australia and New Zealand, the weather is most pleasant and schools are on vacation during the peak dry season of July through September. As a result of the cooler weather during this season, mountain trekking is more popular during this time. Scuba diving is ideal during this time because reef waters are the clearest. It can be wet during the low and shoulder seasons, but they are also cheaper and less crowded.
