Best time to visit Nuku‘alofa

Tonga · 20-year averages

Nuku‘alofa has no real season. The best month scores 78 and the worst 62, a spread of just 16 points, so the honest answer to "when should I go" is whenever the flights are cheapest. The good window runs May to November — 7 months within ten points of the best.

February is the warmest month at 27.4 °C and August the coolest at 23 °C — a 4.4 °C spread across the year. It never reaches 30 °C in an average year, which takes heat off the list of reasons to avoid any particular month.

There is a real wet season here. January and March carry the rain — up to 21 wet days in a month — while June, July and September drop as low as 12. That 9-day gap is the biggest single difference between a good month and a bad one in Nuku‘alofa, and it moves further than the temperature does.

The sea never drops below 24.3 °C, so swimming is on the table year round. Daylight runs from 10.9 hours in winter to 13.4 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are July, September, June. The one to think twice about is March. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
