Traveller notes on Hervey Bay in December
Other months in Hervey Bay
Hervey Bay's forum is clear that January is the wrong month for the whale watching the town is famous for — the season doesn't open until later, running roughly July through November, so January visitors go home without a sighting. It's still hot, humid and good for swimming, though regulars warn to expect tropical downpours; Mon Repos, further along the coast, is flagged as worth the detour for nesting turtles instead.
