Find out what weather awaits you in the city of Onslow right now. Below are up-to-date reports and forecasts necessary for comfortable trip planning.

Onslow welcomes travellers with a hot and dry climate, perfect for those who enjoy the sun and warmth. The weather in this Australian region is remarkably stable: skies are almost always clear, and cloudy days are a rarity. Thanks to the ocean's influence and its geographical location, the town boasts comfortable conditions for a coastal holiday practically all year round.

Seasonal temperature fluctuations are quite mild here, without extreme changes. Summer (from December to February) can be hot, with the thermometer confidently staying above 30°C, while nights remain very warm. The winter months (June–August) bring a pleasant freshness: daytime temperatures drop to a comfortable 20–21°C, reminiscent of the mild season at many global resorts.

The main feature of the local climate is the minimal rainfall. Statistics show that rain falls extremely rarely and in insignificant amounts, even during periods when other tropical regions experience their rainy season. This makes the region an excellent choice for those wishing to avoid weather surprises and enjoy a guaranteed sunny holiday.

For travellers planning to visit Onslow, it is important to note that this corner of Australia features a hot climate. The hottest period falls during the local summer and early autumn. From January to March, average temperatures confidently stay above 30°C, and in December, they come very close to it (around 29.5°C). During these months, daytime heat often reaches 34°C and higher, creating truly hot conditions.

The winter season, which lasts from June to August, brings a welcome mild coolness. Even in the "coldest" month of the year—July—the average temperature is a comfortable 20.5°C, with daytime highs reaching a pleasant 25°C. Nights during this period become fresher: the air cools down to approximately 16-17°C, making winter the ideal time for those who prefer to avoid extreme heat.

Throughout the year, there is a noticeable difference between day and night readings. In transitional seasons, such as April or October, the weather remains summery warm: during the day, the air warms up to 30-31°C. However, nights become significantly more comfortable than in the height of summer (around 20-24°C), creating excellent conditions for evening walks and relaxation.

When planning a trip to Onslow, you can confidently count on sunny weather, as rainfall in this region is extremely rare. The climate here is exceptionally arid, and even on those rare occasions when clouds cover the sky, rains are usually brief and symbolic, having practically no impact on tourists' plans.

There is no distinct rainy season in the city. According to statistics, a slight increase in precipitation frequency is noticeable only in June, with about 4 rainy days recorded, and in February—about 3 days. However, even in these months, the total volume of moisture remains minimal, often not exceeding 1 mm, which suggests a light drizzle rather than heavy downpours.

The driest period, ideal for beach holidays and excursions, runs through the second half of the year. From July to November, the probability of precipitation drops to almost zero: in September, October, and November, rainy days are typically absent altogether. This makes Onslow a wonderful destination for those seeking guaranteed sunshine in Australia.

When preparing for a trip to Onslow, it is worth considering that a predominantly hot and dry climate prevails here. For most of the year, especially from October to April, temperatures remain high, often exceeding +30°C. The foundation of your wardrobe should be items made from light natural fabrics, such as cotton and linen, which are breathable. Be sure to pack t-shirts, shorts, and loose-fitting light-coloured clothing. Given Australia's high solar activity, it is critical to bring reliable sunglasses, a wide-brimmed hat, and sunscreen with maximum protection factor (SPF 50+).

If your trip is planned for the Australian winter (from June to August), the weather becomes milder and more comfortable for outdoor activities. During the day, the air warms up to a pleasant +20…+21°C, but nights can be cool, with temperatures around +16°C. For evening walks and protection from potential ocean breezes, the principle of layering is recommended: bring a light jacket, a windbreaker, or a cosy hoodie that can be easily removed when the sun starts to warm up again.

Precipitation in this region is a rarity, and even in the "wettest" months, it rains for only a couple of days, so heavy raincoats and large umbrellas are unlikely to be needed. It is much more important to ensure comfortable footwear: for excursions and walks around natural attractions, light breathable sneakers or trekking sandals with good foot support are best. And, of course, do not forget your swimwear, as even in the cooler months, the weather often invites you to relax by the water.
