Port Stephens has a mild coastal climate: warm, humid summers and mild winters, with rain spread through the year.
Season by season
Spring (September–November)
Warming seas, whales heading south and fewer crowds than summer.
Summer (December–February)
Hot beach days and boom netting, but the area is packed in the school holidays.
Autumn (March–May)
Warm water, calm days and quieter beaches. One of the best times to visit.
Winter (June–August)
Mild sunny days and whales heading north. Too cool for most swimmers.
