*** 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

Ballina sits at the mouth of the Richmond River, where subtropical conditions keep the water relatively warm for much of the year. Water temperatures in the river follow the seasons closely. In summer, the Richmond River around Ballina typically sits between 24–28°C, feeling warm and comfortable, especially in sheltered stretches away from strong tidal flow. Spring and autumn usually bring slightly cooler conditions, with temperatures around 21–25°C, which still suit swimming on most days. During winter, the water cools to roughly 17–20°C, mild enough for a short swim, particularly on clear, sunny afternoons.

Swimming Conditions

Swimming in the Richmond River at Ballina is generally allowed, but conditions vary depending on location and recent weather. Upstream and calmer sections are preferred, where currents are gentle and boat traffic is lighter. Being a tidal river, water temperature and clarity can change with the tide, and the water may feel cooler on an incoming tide from the ocean. After heavy rain, runoff can lower temperatures and affect water quality, so swimming is best avoided then. In stable conditions, especially through summer, the Richmond River offers a pleasant alternative to ocean swimming, with warmer water and more protected conditions than the nearby beaches.
