When to go
The best time to travel to Niue is from
mid-May to October, since it is the coolest and sunniest period of the year. It must be said, however, that it is the winter, and it can sometimes get a little cool in the evening and at night, so it may be a good idea to bring a sweatshirt or sweater.
What to pack
In
winter (June to August): bring light clothes for the day, a scarf for the breeze, a sweatshirt for the evening, and possibly a light raincoat or umbrella.
In
summer (December to February): bring tropics-friendly, loose-fitting clothing, a sun hat, a scarf for the breeze, a light sweatshirt for the evening, and a light raincoat or umbrella.
