Cold
Cold water ahead. Cold shock is a real risk on entry. Limit your time in.
Ground temperature is 12.1°C. Air has averaged 9.5°C today. Low flow may allow the water to warm slightly. 25mm of rain in the last 7 days may have cooled and clouded the water.
Derived from groundwater, air temperature, solar, wind, river flow, and snow. Not a direct measurement.

Frequently asked questions
How is the river water temperature estimated?
River temperature is estimated using a combination of indicators: soil temperature at 54cm depth (groundwater proxy), air temperature, solar radiation, wind speed, river discharge, and snow depth. This is a heuristic estimate, not a direct measurement or a calibrated physical model.
What do the temperature categories mean?
Each category covers a 4 degree C band derived from the estimated midpoint: Warm (20°C+, comfortable without wetsuit), Comfortable (16-20°C, most swimmers fine), Cool (12-16°C, wetsuit optional), Cold (8-12°C, wetsuit recommended), Very Cold (4-8°C, wetsuit essential), Ice Risk (below 4°C, experienced only).
How does river flow affect temperature?
Higher river discharge typically means colder water. Fast-flowing water has less time to warm from solar radiation, and high flows often indicate recent rainfall or snowmelt. Low flows in summer allow the water to warm more.
How does snow affect river temperature?
Snow depth in the catchment indicates potential snowmelt runoff. When snow is melting, rivers receive very cold water that can significantly lower the temperature. This indicator is most relevant in winter and spring.
How accurate is this estimate?
Indicator-based estimates are typically accurate to within 2-4 degrees C. Accuracy depends on river size, flow conditions, and local factors like shading and tributaries. Community temperature reports from swimmers provide the most reliable local data.
