SEPA makes real-time rainfall data available online



Real-time Scottish rainfall data is now available on SEPA’s website.

The site provides rainfall information for over 270 locations across Scotland.  This may be helpful for a wide range of uses such as flood forecasting, farming, angling and canoeing. Each gauge is represented by a dot on a map which can be clicked to reveal the gauge name and rainfall amounts in a range of hourly, daily, monthly and annual formats. There is also the ability to search by station name.

In addition to running these intensity gauges linked by telemetry, SEPA also manages a network of manually read storage gauges operated by public volunteers. The complete network captures the distribution of rainfall across Scotland and is essential for understanding trends and environmental change. The data is also submitted to the Met Office’s national rainfall archive for which SEPA provides the majority of observation sites in Scotland. This archive of reliable long-term data is used by government bodies, industry and researchers to model and inform weather and flood forecasting, climate research, water resource management and the wellbeing of communities.

Rainfall siteRichard Brown, SEPA’s Head of Hydrology, said:

“We’re releasing this rainfall beta test site so people can look at the data, use it, and give us feedback on how useful it is and what we could do to improve it. It’s important that we produce information and evidence that will be used by people to make decisions – and to do that we need to ensure that we are providing what they really need.”

Data from the SEPA’s network of rain gauges is collected automatically but it can take an hour or two to process through the system before it appears on the website. Sometimes automatic collection is delayed for various reasons such as maintenance, system outages or failure of the public telemetry links. If data from a gauge is more than 12 hours old the dot on the map will show as grey. SEPA staff are made aware when data falls behind and will work to fix the problem as soon as possible. There is no need to contact SEPA if there are gauges showing as grey on the map.
