Nyngan’s weather is defined by a semi-arid climate with hot, dry summers and mild winters; the live forecast above gives the day’s conditions, but the seasonal pattern is what makes planning straightforward.
What’s the typical weather pattern in Nyngan?
Nyngan sits in central-west NSW, so expect a big swing between summer highs and winter lows, with most rain falling in the warmer months.
- Summer (Dec–Feb) – average maximums around 33–35°C, often pushing 40°C on heatwave days. Nights stay above 18°C.
- Winter (Jun–Aug) – daytime highs near 15–17°C, overnight lows can drop below 5°C. Frost is common in July.
- Rainfall – annual average about 400–450 mm, with a slight peak in summer (especially January). Winters are usually dry.
- Wind – afternoon north-westerlies in summer can bring dust; winter has lighter westerly breezes.
How can I check Nyngan weather for the next week or longer?
The live forecast above covers the short term, but for planning ahead use the 14‑day or 28‑day outlooks available from the Bureau and other services.
- For a nyngan weather 14 day forecast, look for the extended forecast on BOM or Weatherzone – it’s reliable for temperature trends but less so for precise rain amounts.
- The nyngan weather radar (available via BOM’s Sydney or Moree radar loops) helps spot approaching storms, especially in summer.
- If you need weather in nyngan 10 days or a nyngan 28 day forecast, check aggregated sites such as Elders, which also publish a nyngan weather elders page.
- Comparisons with nearby centres like Dubbo weather (about 130 km north) or Cobar weather (170 km north-west) can give context—both have similar semi‑arid conditions, though Cobar is slightly hotter.
Does Nyngan get frost in winter?
Yes, frost occurs regularly from June to August, especially on clear, calm nights. The average minimum in July is 3°C, but ground frost can happen even when air temps hover just above zero.
When is the wettest month in Nyngan?
January is typically the wettest month, with about 50 mm of rain. Most summer rain comes from thunderstorms or troughs, so falls are often heavy but short-lived. Winters are very dry.
How does Nyngan weather compare to Dubbo or Cobar?
Dubbo and Cobar share the same semi‑arid pattern. Dubbo is slightly cooler and wetter (annual average ~480 mm), while Cobar is hotter and drier (~350 mm). Nyngan sits between them in both temperature and rainfall.
