Best time to visit Avarua
Cook Islands · 20-year averages
June is the best month in Avarua, scoring 81 out of 100, with January the weakest at 63. The 18-point spread means timing is worth planning around without being decisive. The good window runs June to October — 5 months within ten points of the best.
February is the warmest month at 27.1 °C and August the coolest at 23.5 °C — a 3.6 °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. February to March carry the rain — up to 22 wet days in a month — while June to August drop as low as 11. That 11-day gap is the biggest single difference between a good month and a bad one in Avarua, and it moves further than the temperature does.
The sea never drops below 24.8 °C, so swimming is on the table year round. Daylight runs from 10.8 hours in winter to 13.4 in summer, enough to notice on a sightseeing itinerary.
The three strongest months are June, August, July. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
