Hours of Sun in September

Expect a longer and sunnier day in September in Niue than in the previous months, so you have plenty of time to dine al fresco after your day of exploring the tiny island nation. It is worth noting that due to the days being so hot, the evenings feel significantly cooler so the chilliest of travellers will want to pack a light cotton layer to be able to withstand the evening breeze. In September, the average day sees 12 hours of sunshine and 5 hours of bright sunshine, usually around midday.

UV Levels During September

It’s mostly with the UV levels that the travellers will be able to notice the dry season coming to an end. In September, the average UV index jumps to 11 which is classified as extreme. This means that even tanned skin will have a good chance to burn should it be left unprotected. Sunhats and sunscreen are a must whenever going outside. Reapply every two hours or after a swim.

Because Niue has such beautiful underwater sea life, we have prepared a list of reef-safe sunscreen for you. It will be your way to enjoy Niue and leave it as you found it for generations to come. And speaking about the next generation, if you are travelling with kids, check out this list of kid-friendly sunscreens designed especially with fragile kid’s skins in mind.

Rainfall in September

The great thing about September is that although almost every indicator starts moving toward the hotter and more humid “wet season”, the average number of rainy days is still quite low. Only a handful of days will experience showers, most of which are usually short, warm and pass well before you have time to unpack your rain jacket. Still, it is worth packing one just in case. But it’s true, Niue is a very small and flat island in the middle of the massive Pacific Ocean, so weather passes above it as smooth as they would pass over water.

The average rainfall in Niue in September is 138mm / 5.4” spread over an average of 5 days. This means that on average, only 5 days in August experience some short showers.
