Weather in McArthur River

To ensure your journey is perfect, check the weather forecast in McArthur River in advance. Below, you will find current data and charts to help you plan your day effectively.

The climate in McArthur River can be described as hot and tropical, with a distinct division into wet and dry seasons. High temperatures persist throughout the year, and even in the coolest months, the air warms up to comfortable levels, rarely dropping below +22°C during the day. This destination is suitable for those who love warmth and sunshine, as cold weather is practically non-existent here.

The year is clearly divided into two periods. From November to March, the hot and humid season prevails: the average temperature rises above +30°C, peaking at +36°C, and the number of rainy days increases significantly (up to 18 days in January). During this time, the air is saturated with moisture, which may intensify the sensation of heat, but the surrounding nature becomes particularly lush and green.

With the arrival of the local "winter" period (from May to September), the weather changes dramatically. The dry season sets in, during which precipitation is almost entirely absent — from June to September, rainy days are usually not observed at all. Temperatures become milder and more pleasant for walking, ranging from +22°C to +26°C, while nights bring a refreshing coolness. This is arguably the most comfortable time to visit the region.

The climate in McArthur River is characterised by consistently high heat, which is typical for the northern regions of Australia. The hottest period here spans from November to January: the average air temperature holds steady at 30–31°C. The peak heat often occurs in October and December, when daytime maximums regularly exceed the 36°C mark. During this time, even the nights remain very warm, not dropping below 24–26°C, which, combined with seasonal rainfall, can create a feeling of humidity.

The period from June to August, which corresponds to the Australian winter, brings long-awaited freshness, although the weather remains warm by summer standards. July is considered the coolest month with an average temperature of about 22.3°C. This time of year sees the most comfortable temperature regime: during the day, the air warms up to a pleasant 29°C, while nights become noticeably cooler — the thermometer can drop to 15–16°C.

Travellers should take into account significant daily temperature fluctuations, especially during the dry season. The difference between the daytime maximum and the nightly minimum often reaches 14 degrees. This means that after a hot sunny day, the evening may seem quite fresh, so a light jacket or jumper may come in handy even in this tropical climate.

Precipitation in McArthur River is distributed unevenly throughout the year, forming clearly defined wet and dry seasons. When planning a trip to this corner of Australia, it is important to consider that the character of the weather here depends directly on the month. The year is clearly divided into a period of frequent rains and a time of absolute dryness.

The wet season here falls during the Australian summer and early autumn. The rainiest month is January, when precipitation is observed on average for 18 days. A high probability of rain also persists in February and March (14–15 days with precipitation). During this period, an umbrella will become your essential companion, although the rains are often short-lived.

The dry season, on the contrary, is ideal for those who prefer clear skies. From June to September, the probability of precipitation is reduced to a minimum: statistics show an average of 0 rainy days in these months. May and October are transitional periods when rains occur extremely rarely, no more than 1–2 days for the entire month.

When packing for McArthur River, primarily focus on the region's hot climate. The foundation of your wardrobe should consist of light clothing made from natural, breathable fabrics, such as cotton or linen, which will help you better tolerate high temperatures reaching +36°C in the summer months. Be sure to bring a wide-brimmed hat, high-quality sunglasses, and sunscreen with a high protection factor (SPF 50+), as the sun in Australia is very active.

If your trip is planned for the period from May to August (local winter), it is worth considering the daily temperature changes. During the day, it will be comfortable in a t-shirt and light trousers or shorts, but evenings and nights can be cool (temperatures drop to +15°C), so pack a light jacket, windbreaker, or hoodie in your suitcase — the principle of layering will be useful here. In the rainy season (from November to April), despite the heat, there may be wet days, so a light raincoat will not be amiss.

For walks and excursions, choose comfortable closed shoes with flat soles, suitable for walking on uneven terrain. Also, do not forget swimwear, as you will surely want to refresh yourself in the hot weather. Given the tropical features, a reliable insect repellent will be a useful accessory, and a reusable water bottle will help maintain hydration during long walks under the sun.
