Tonga travel guide

Best time to visit Tonga from the UK

Best value: Apr–May, Oct–Nov. Jul–Oct for humpback whales. Busiest and priciest: Jun–Sep.

Each bar is the average temperature in Nuku'alofa for that month, and its colour shows the season for visitors: best value (good weather, fewer crowds and lower prices), busiest and priciest, or quiet (off-peak, sometimes because the weather is poorer).

• Our pick: April and MayThe warmest of the best-value months (25–26°C), with fewer crowds than peak season.
• Peak season: Jun–SepUsually 22–24°C. The busiest time, so book flights and rooms early and expect higher prices.
• Quiet season: Dec–MarAround 26–27°C. The cheapest and least crowded time, though often because of rain or heat.
• Warmest: February (27°C) · coolest: August (22°C)A 5°C swing between the warmest and coolest months.
