Newton weather is generally mild and Mediterranean, with warm, dry summers and cool, wet winters. The live forecast above shows the current conditions, but the key takeaway is that this suburb in South Australia’s Adelaide Hills often sits a few degrees cooler than the city centre.
What makes Newton’s weather different from Adelaide’s?
Newton lies about 10 kilometres east-northeast of the Adelaide CBD, at a slightly higher elevation. This means it regularly records temperatures 1–3°C lower than the city, especially on summer afternoons. The suburb’s position in the foothills also means it can catch more easterly winds and receive slightly higher rainfall than the plains. For a day-by-day breakdown, check the Adelaide weather page as a general guide, but subtract a degree or two for Newton itself.
What about hourly changes and tomorrow’s outlook?
The weather Newton hourly data (available in the live forecast) is the most reliable way to track temperature shifts, as conditions can change quickly when sea breezes arrive from the Gulf St Vincent. For weather Newton tomorrow, expect a similar pattern: mornings often start cool and foggy in winter, or clear and crisp in summer, before warming through the day. You can cross-check with the Bureau of Meteorology’s bom newton observations for real-time station data.
Does Newton get severe weather warnings?
Yes. Newton falls within the Adelaide region for severe weather warnings, including heatwaves, thunderstorms and bushfire danger days. The Severe Weather Warning page lists current alerts for your area.
How does Newton SA weather compare to the coast?
Newton is typically 2–4°C cooler than coastal suburbs like Glenelg in summer, and less humid. In winter, it can be 1–2°C colder overnight, increasing the chance of frost.
Where can I find reliable Newton weather data?
The Bureau of Meteorology (BOM) provides official observations for the Adelaide Hills, including nearby stations. Weatherzone and Elders also offer localised forecasts and radar imagery.
