Water Temperature in Snowy River at Marlo: Daily Trends, Historical Records, and Forecast
⚠️ River water between 10 and 15°C is cold but manageable for short swims, especially on sunny days with warm air temperatures. The moving nature of a river can make the water feel colder than the actual reading, particularly in shaded or deeper sections. Casual swimming is usually brief, with wetsuits often preferred. Windy or cool weather can significantly reduce comfort, even when the air temperature is mild.

*** Forecast - Our water temperature forecast
Actual river water temperatures may vary by several degrees from the reported values, particularly after heavy rainfall or periods of changing weather. Rainfall, river flow rates, and runoff from cooler upstream areas can significantly affect water temperature, especially in flowing sections and shaded stretches. Air temperature and cloud cover also play an important role, with warm, sunny conditions helping rivers warm up more quickly. As a result, noticeable temperature differences can occur along the same river.
Our forecast is based on a proprietary mathematical model that takes into account real-time river temperature changes, historical data, seasonal patterns, river flow conditions, recent rainfall, and local air temperature. We also factor in broader weather conditions specific to each region of Australia to improve accuracy.

Location & Local Information
Marlo sits right at the mouth of the Snowy River, where fresh alpine water meets tidal influence from Bass Strait. Because of this mix, water temperature here is a little more variable than further upstream. In summer, from December to February, the Snowy around Marlo is usually in the range of about 18–22°C, sometimes edging a bit warmer in sheltered stretches on hot, still days. Spring and autumn are milder, with temperatures generally around 14–18°C. Winter brings cooler conditions, often sitting at roughly 10–13°C, especially when cold ocean water pushes upstream with the tide. Even so, it’s noticeably warmer than the river’s alpine headwaters.
Swimming Conditions
Swimming in the Snowy River at Marlo is allowed and fairly popular in summer, particularly on calm days when the river looks more like a wide estuary than a fast-flowing river. The water is usually clean, and in the warmer months it’s comfortable enough for a decent swim, not just a quick dip. Locals tend to choose sheltered areas away from strong tidal flow. Still, conditions can change quickly. Tides, currents and boat traffic all play a role, and water temperatures can drop suddenly when the tide turns. With a bit of awareness and sensible spot choice, swimming here can be refreshing and enjoyable during the warmer part of the year.
