Weather in Avarua in March

A good month. March is a solid month to be in Avarua. You should expect rain on 22 days of the month, which is more days wet than dry.

March ranks 11 of 12 — near the bottom of Avarua's year. June is the month that works, and the swing between the two is 18 points, which is a different holiday rather than a slightly better one. Worth keeping in perspective: March is the weakest month of Avarua's year and it is still a perfectly good one. The downside here is small.

Rain on 22 of the month's 31 days, 6 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. 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 March 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 March day reached 29.1 °C and the coldest night fell to 23.9 °C, and the wettest single day dropped 92 mm — roughly 46% of the month's rain in one day.

March is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest March on record still delivered 415 mm against 50 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 198 mm average is a reasonable planning figure, not a promise.

Wind sits around 17.8 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 March sits in the year

Temperatures hold steady either side: 27.1 °C in February, 27.1 here, 26.6 in April. Nothing about the timing within the month matters much. Rain is the thing that moves: April brings 5 days less of it, so pushing the dates later buys drier weather.

Daylight in March

12.2 hours of daylight, losing 0.6 hours across the month. That is between Avarua's extremes of 13.4 and 10.8 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 28.1 °C in March — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

March 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 — within a degree on temperature, 1 day less rain. Faaa is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: March works, with June the better month by 17 points if the dates can move. If they cannot, nothing here should stop you booking.
