Perth Weather in December

Long summer days

December feels warm and mostly dry in Perth, with daytime highs around 25°C and evenings near 18°C. Rain is uncommon, and long sunny days leave plenty of time outside. Kings Park is lovely for a walk, while Cottesloe and City Beach suit a swim or an afternoon by the water.

The heat can feel tiring on exposed paths, so save a long stroll around Fremantle's historic streets for later in the day. Families with young children may prefer beach mornings to sticky afternoons.

Christmas in Perth

Christmas brings a quieter city centre, as many shops and restaurants close or shorten their hours on Christmas Day. Perth also marks Boxing Day and New Year's Eve; riverside spots around Elizabeth Quay and the South Perth foreshore draw people for evening celebrations.

Check transport arrangements for holiday travel, especially if you're heading to Fremantle or the coast. The CAT buses in central Perth are free, but services can change on public holidays.

Busy season, beach plans

December is the start of summer school holidays, so beaches and family attractions get busier. It's high season, and accommodation and flights can cost more than in quieter months. For a calmer outing, head to Kings Park on a weekday rather than joining the beach crowds.

A Perth-specific tip: take the ferry from Barrack Street Jetty to Rottnest Island, but check its holiday timetable before setting out. The island's bays are rewarding for swimming, though there's little shade on many walking routes. If you're visiting for New Year's Eve, expect popular riverside viewing spots to fill up.
