Port Douglas in November

May through October brings perfect weather - sunny days around 26°C and low humidity. This is peak season, so book reef tours early and expect higher accommodation prices. September and October offer the best balance of good weather and smaller crowds. November through April is wet season. It's hot, humid, and cyclones are possible. But here's the thing - rates drop by 40%, and the rainforest looks incredible after the rains. Just pack an umbrella and be flexible with outdoor plans. Stinger season runs October to May, so you'll need protective suits for swimming.
