All Months
April through October delivers the sweet spot – dry trade winds, comfortable temperatures around 24°C, and minimal rainfall. July and August see the most visitors, so book accommodations early. November through March brings higher humidity, occasional cyclones, and daily afternoon showers, though mornings often stay clear. The shoulder months of April and October offer the best value – fewer crowds, lower accommodation rates, and still-excellent weather. Traditional festivals like Te Maeva Nui (Constitution Day) in August showcase authentic Polynesian culture. December to February can be sweltering, with temperatures reaching 30°C and humidity that makes afternoon activities uncomfortable.
