If you plan to visit Dunedin, here are a few climate details you should keep in mind:
The major seasons of Dunedin are Summer (October to March) and Winter (April to September). Spring intermingles with summer and usually lasts from September to November while autumn lasts from March to May. The city, like much of Southern New Zealand, is cloudy and damp but summer temperatures are mild and the climate is dry. Winters tend to be cold and have the highest rainfall patterns of the four seasons.
The best time to visit Dunedin is between the months of September to April.
