Finally, choosing when and where to go will define the character of your trip. Because New Zealand sits in the Southern Hemisphere, the seasons are the reverse of those in North America or Europe. Summer, which spans December through February, offers the best weather for the country’s famous coastal tracks but also brings the largest crowds. For those seeking a quieter experience, the shoulder seasons of autumn and spring offer stunning colors and active waterfalls, though the weather becomes notoriously unpredictable—often delivering “four seasons in one day.” Whether you are drawn to the geothermal wonders of the North Island or the dramatic alpine peaks of the South Island, you should always pack high-SPF sunscreen. The thin ozone layer in this part of the world means the sun is much stronger than many visitors expect, making skin protection a vital part of your daily routine.
