Newcastle’s seven-day forecast, shown in the live forecast above, points to a typically mixed late-autumn week with mild days, cooler nights and a possible shower or two mid-week. The Hunter coast can expect a moderate north-easterly breeze turning south-easterly later, keeping temperatures near average for May.
How will the week shape up?
According to the live forecast above, most days will see a top around 21–23°C, with overnight lows dipping to 11–14°C. A weak trough may bring patchy rain from Wednesday into Thursday, especially over the lake catchments and coastal suburbs. After that, a high-pressure ridge builds, delivering mostly sunny skies for the weekend. For a longer view, check the Australia weather hub or the Sydney Weather page for regional comparisons.
What about wind and UV?
Winds will be light to moderate throughout the week, shifting from north-easterly to south-easterly by Friday. The UV index peaks at 3–4 around midday—moderate for this time of year, so sunscreen is still sensible if you’re out on the harbour or at the beach.
Will it rain this week in Newcastle?
The live forecast above shows a 60% chance of light showers on Wednesday, clearing by Thursday. The rest of the week looks mostly dry. If you’re after a longer outlook, the 14‑day forecast suggests similar conditions—check the newcastle weather 14 day forecast bom for official updates.
When will the next cool change arrive?
A cooler south‑westerly change is expected to move through on Friday, dropping overnight lows to around 11°C. That pattern is typical for mid‑May along the Hunter coast, so you’ll want a jacket for the early morning or evening walk.
