What this means
Truro Harbour reads −0.05 m as of 17 Oct 2026, 18:30 BST. There is no published reference for this river yet, so we can't say whether that is high or low for the season.
It has dropped 0.47 m over the past 24 hours. In the last month it has stayed between −0.41 m and 1.38 m.
The agency publishes no normal range for this gauge yet, so we show the trend only. How to read levels
Fishing and paddling
Watch the direction of travel. A rising river after rain behaves very differently from one that is dropping and clearing.
Flood alerts and warnings come from the Environment Agency.
Weather at the gauge
Rain in the last 3 days: 2.6 mm. Rain that falls upstream can take hours or days to show up at a river gauge.
Forecast: Open-Meteo
