Traveller notes on Port Douglas in March
Other months in Port Douglas
Port Douglas's forum calls October one of the best months — warm, ahead of the wet season's humidity, with reliable reef conditions. The catch regulars flag: stinger season starts around October and runs into the following year's autumn, so ocean swimming without a stinger suit is off the table even on an otherwise perfect-looking day.
