What The Weather Will Be Like This New Year’s Eve in Perth

New Year’s Eve in Perth is shaping up to be a classic hot, dry summer day. Early outlooks point to daytime temperatures sitting around 30–34°C in coastal suburbs, climbing closer to 36–38°C inland, depending on how much heat builds in the days leading up.
Expect calm, sunny conditions through the morning and early afternoon, followed by the arrival of the Fremantle Doctor in the late afternoon (usually between 3–5pm). Coastal areas will feel the relief first, while inland suburbs tend to hold onto the heat well into the evening.
By fireworks time, temperatures typically settle around 25–28°C, staying warm but far more comfortable with light evening breezes. Rain is unlikely, though some humidity can creep in if an offshore trough develops—nothing dramatic, but enough to make breathable outfits and hydration essential.

New Year’s Day in Perth almost always delivers heat and high UV, and early signals suggest 2026 will be no different. Expect a warm-to-hot start, with temperatures rising quickly through the morning under a strong midday sun.
UV levels are typically extreme, even with minimal cloud, making sun protection non-negotiable. Beach conditions are usually best early, before winds strengthen and crowds peak.
By mid-afternoon, the Fremantle Doctor is likely to return, cooling coastal suburbs by around 4–6°C and creating ideal conditions for ocean swims, shaded pub lunches or breezy park hangs near the water. Inland areas will stay hotter for longer, particularly if overnight temperatures remain elevated.
Overall, conditions are likely to favour early beach visits, indoor or shaded plans during peak heat, and outdoor activities later in the day once the breeze settles in.

A little strategy goes a long way when Perth turns the heat on.
Best time for fireworks:
Aim to arrive at river or beach vantage points in the late afternoon, once the sea breeze has kicked in. Prime spots fill early, shade is limited, and exposed areas stay hot until the Fremantle Doctor arrives.
Heat-safe timing for outdoor plans:
Schedule outdoor parties, picnics or walks for late afternoon or evening on NYE. On New Year’s Day, avoid the 12–4pm heat window, especially if temperatures push into the high-30s.
What to pack for recovery hangs:
Think SPF50+, hat, sunnies, a big water bottle, beach gear, and something for shade. If you’re heading out early, pack light layers for when the breeze picks up later.
Crowds, wind & transport tips:
Expect beaches and riverfront areas to hit capacity early on NYD. Wind can affect exposed picnic setups, so sheltered spots are key. Check transport changes and free travel windows for NYE events, as services and road closures are common.
