The best time to go to Te Anau is during the summer months, from December to February, when the weather is warmest and most activities are fully operational.During this period, you can expect average daytime temperatures around 68°F (20°C), making it ideal for exploring the natural surroundings. The extended daylight hours, with up to 15 hours of sun, allow for longer excursions into Fiordland National Park. This season is great for couples and families looking to maximize their time outdoors, whether it's hiking the Kepler Track or taking a boat cruise on Lake Te Anau.The shoulder seasons of spring (September to November) and autumn (March to May) also offer a pleasant experience with fewer crowds and comfortable temperatures averaging around 59°F (15°C). Spring brings blooming native flora, while autumn showcases beautiful fall colors, particularly around the lakeside. These seasons are well-suited for travelers seeking a more tranquil visit while still enjoying most of Te Anau's attractions, including the Te Anau Glowworm Caves.While winter (June to August) is generally colder, with temperatures around 46°F (8°C), it offers a unique, quiet beauty, especially for those interested in snow-capped mountain views and fewer visitors. Some activities may have reduced schedules, but Milford Sound cruises still operate, offering a dramatic perspective on the fiords.
