RAW DATA as at 15:24 on 26 Jul 2021
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 Gauge||Actual height|
|Kingston flow gauge||flow rate 33 cumecs (m3/sec) |
as at 15:00, 26 Jul - 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
