Thames NOW

Latest news on what the river is actually doing: Barrier, Tides, River flow, Floods

Caution: Based on automated data capture. Accuracy not guaranteed. See notes below.

SUMMARY as at 17:24 on 17 Jan 2020

 - Sorry, no Barrier information available
 - River level in Central London close to prediction
 - River flow at Kingston is VERY STRONG. This is likely to result in significantly higher water levels than predicted (at both high and low tide) between Richmond and Putney. High tides could also be earlier than predicted.
 - Flood Alert no longer in force

FLOOD ALERT for Thames Riverside, Putney to Teddington

No longer in force as at 09:59, 17 Jan
For flood alerts and warnings for other Thames areas, see the Environment Agency's Flood Information Service.

If the PLA flow status differs from the reported Kingston flow above, this is usually because the latter is more recent.

RAW DATA as at 17:24 on 17 Jan 2020

For those of you who prefer to see the actual numbers on which the summary above was based, here is the raw data. Please note the explanations and legal note below the data.

Tide GaugeActual height
Actual height
Kingston flow gauge flow rate 332 cumecs (m3/sec)
as at 17:00, 17 Jan - latest available data

*  CD: Height of water level in metres above local Chart Datum.
AOD: height of water level in metres Above Ordnance Datum, which enables a direct comparison with known land heights. See this page for more information.

Tide gauge data is obtained in real time from the Port of London Authority (PLA), based normally on measurements in the previous 5 minutes. Actual tide heights are shown relative to both the local chart datum and the Ordnance Datum. "Surge" is the difference between the actual height and the prediction in the tide tables, which typically is caused by current or recent weather conditions. The Kingston flow gauge reading and flood alert information are obtained from the Environment Agency (EA) using their real-time data API (Beta). The barrier open/closed status is based solely on the difference in recorded river levels either side of the barrier (Charlton & Silvertown) and assumes accurate readings from those gauges.

I am grateful to PLA and EA for permission to use the above data.

Legal note: The recording and capture of the data is performed by automatic processes, and the data is essentially unvalidated at the time of display here. Accuracy is not guaranteed. PLA, EA and I do not accept any responsibility in law for the information presented here. - Richard Jennings
