The Fishing Seasons in Tonga

When is the best time to fish in Tonga?

The Seasons in Tonga

So if fishing is good in Tonga year-round, what is the climate like? Tonga has two distinct seasons, winter or the “dry season” and summer or the “wet season”.

The winter season is between May and November, which is also known as the dry season. Temperatures are typically 19-29°C (66-84°F), with the rainfall being 110mm (3.9″) per month. The sea temperatures are usually around 24°C (75°F).

The summer season is between December and April, which is also known as the wet season. Temperatures are typically 23-31°C (74-88°F) and Tonga experiences more frequent rainfall of 210mm (8.3″) per month. The sea temperature is warmer at 28°C (82°F).

In short, either season provides many good fishing days, but perhaps a little less so in summer when sea conditions can sometimes get too rough to be appealing for fishing.
