The best time to go to Catlins Forest Park is during the warmer, drier months, ideally from November to April.
This period typically offers the most pleasant weather for exploring the park's natural attractions. You'll find temperatures are milder, making activities like hiking to waterfalls or visiting the coastal viewpoints much more comfortable. While the Catlins can experience rain at any time of year, these months generally have less of it, meaning clearer skies and better opportunities for photography and outdoor adventures.
For those eager to spot wildlife, particularly penguins and seals, November to February is an excellent time. This coincides with nesting and breeding seasons, increasing your chances of seeing these fascinating creatures along the coastlines, especially around Nugget Point Lighthouse or Curio Bay. The longer daylight hours during these months also allow for more extensive exploration.
If you prefer a quieter experience and don't mind slightly cooler temperatures, late autumn (April) can also be wonderful. The crowds thin out, and the landscape often takes on beautiful autumnal hues.
