The climate in the city of Mount Gambier can be described as temperate maritime, characterised by mildness and a lack of extreme temperature fluctuations. The weather here is favourable for travel for most of the year: there is no exhausting heat in summer, and no severe frosts in winter. However, tourists should take into account the distinct seasonality, which affects the number of sunny days and rainfall.

The summer months (from December to February) in this region of Australia are generally warm and dry. The average daytime temperature holds at a comfortable mark of around +24°C, and rain falls extremely rarely, creating ideal conditions for viewing natural attractions. Winter (from June to August), on the other hand, brings coolness and increased humidity: daytime temperatures drop to +10...+13°C, and the number of rainy days increases significantly, peaking in July and August.

Spring and autumn serve as pleasant transitional periods when the weather changes gradually. If you are planning a trip during the off-season, it is worth being prepared for some variability: a clear sky can quickly be replaced by cloudiness. Overall, Mount Gambier offers fairly predictable weather conditions, where the main recommendation for a tourist would be to have a light jacket or umbrella in the cool months and sun protection products at the height of summer.

The climate in Mount Gambier can be characterised as temperate and comfortable, without extreme heat or severe cold. The warmest time of the year is the Australian summer: in January and February, the average daytime temperature fluctuates in the range of 23°C to 24.2°C. This time is ideal for tourism, as the weather is pleasantly warm, allowing you to enjoy walks in the fresh air without the risk of overheating under the scorching sun.

The winter period, which lasts from June to August, brings noticeable coolness. July is traditionally considered the coldest month of the year: during the day, the air warms up to only 12.9°C, and the average temperature drops to 10.4°C. Winters here are mild but fresh; night-time readings in this season reach a minimum of around 7.9°C — 8.0°C, so travellers are advised to stock up on warm clothes and windbreakers.

It is also worth paying attention to daily temperature fluctuations, which are most perceptible in the summer months. Despite warm days, nights in Mount Gambier can be quite bracing: even in January, the temperature after sunset drops to 14.1°C. In spring and autumn, the temperature regime is more even, offering tourists a "golden mean" with average daytime figures of around 17°C — 20°C.

Precipitation in Mount Gambier is distributed unevenly throughout the year, demonstrating distinct seasonality. Travellers should consider that there is a clear division here into a wetter winter period and a comparatively dry summer. Snow in this region is an exceptional phenomenon, so precipitation almost always implies rain.

The rainiest season falls during the Australian winter and the beginning of spring. The peak of inclement weather is observed in July and August, when the highest number of days with precipitation is recorded — up to 16–17 days per month. It rains frequently during this period, so having waterproof clothing and an umbrella will be a necessity for comfortable walks.

The summer months, especially January and February, are conversely the driest of the year. At this time, the probability of getting caught in the rain is minimal: statistics show only about 3–4 rainy days per month. This makes summer the best time to visit the region's famous volcanic lakes and caves without fear that the weather will spoil your plans.

A trip to Mount Gambier requires a thoughtful approach to your wardrobe, as the weather here can be changeable. In the summer months (from December to February), the climate is mild and pleasant, so the basis of your luggage should consist of light clothing made from natural fabrics: t-shirts, shorts, and summer trousers. However, given the temperature drops, even in summer, evenings can be cool, so be sure to take a light jacket, cardigan, or hoodie with you. Also, do not forget about comfortable footwear for walking, as you will surely want to explore the region's famous volcanic lakes and caves in comfort.

If you plan a trip in winter (from June to August) or during the off-season, be prepared for cooler and wetter conditions. At this time of year, it is best to use the principle of layering: wear thick jumpers or fleece tops underneath, and a windproof jacket on top. Since the number of rainy days significantly increases in the winter period, a compact umbrella or a high-quality raincoat will become your best assistants, allowing you to enjoy walks regardless of precipitation.

Regardless of the season, remember the active Australian sun. Sunglasses, a hat, and cream with a high protection factor (SPF) are necessary all year round, even if it is cloudy outside. The weather in Mount Gambier can change quite quickly, so having a spare pair of warm socks or a scarf in your backpack will help you feel cosy in any situation.
