Best time to visit Port Douglas

August is the best month in Port Douglas, scoring 90 out of 100, with February the weakest at 50. The 40-point spread means timing is worth planning around without being decisive. The good window runs June to October — 5 months within ten points of the best.

December is the warmest month at 30.4 °C and July the coolest at 24.7 °C — a 5.7 °C spread across the year. Around 54 days a year top 30 °C, concentrated in December and the months either side.

There is a real wet season here. January to March carry the rain — up to 25 wet days in a month — while July to October drop as low as 6. That 19-day gap is the biggest single difference between a good month and a bad one in Port Douglas, and it moves further than the temperature does.

The sea never drops below 24.7 °C, so swimming is on the table year round. Daylight barely moves: about 13.1 hours whatever the month, which removes one variable from the decision entirely.

The three strongest months are August, September, July. The one to think twice about is February. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
