Weather in Avarua in November

Cook Islands · 20-year averages, November

A good month. November is a solid month to be in Avarua. You should expect rain on 16 days of the month, which is more days wet than dry.

November ranks 6 of 12 in Avarua: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain on 16 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average November reaches 30 °C; the day barely swings — 0.8 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 27.9 °C and the coldest night fell to 21.1 °C, and the wettest single day dropped 83 mm — roughly 58% of the month's rain in one day.

November is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest November on record still delivered 243 mm against 57 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 144 mm average is a reasonable planning figure, not a promise.

Wind sits around 18.5 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How November sits in the year

Temperatures hold steady either side: 24.2 °C in October, 25.1 here, 25.9 in December. Nothing about the timing within the month matters much.

Daylight in November

November is at or near the longest days of Avarua's year: 13.1 hours of daylight, gaining 0.4 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 26 °C in November — warm enough to stay in as long as you like. The sea peaks at 28.1 °C in March and bottoms out at 24.8 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

November in Avarua versus nearby

If Avarua is one option among several, the nearby comparison is worth making. Vaitape is close enough to be a coin toss — 2.3 °C warmer, 1 day more rain. Faaa is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: November works, with June the better month by 12 points if the dates can move. If they cannot, nothing here should stop you booking.
