Created: 23 October 2019 Updated: 14 January 2023We have two types of rainfall network.  Data from automatic gauges collected at a high resolution and data from a network of volunteers.We have approximately 1000 automatic gauges and 1400 manually read gauges across England. We can provide recent and historic data from these gauges.Data from automatic gauges is available at a range of resolutions from event data (time of tip), 15 minute totals, daily and annual rainfall totals.The automatic gauges are operated by Hydrometry &amp; Telemetry teams. Data from manually observed gauges is typically daily or monthly accumulated rainfall totals and sent to us at regular intervals.Please note this is unvalidated data and could potentially contain errors due to faulty instruments or on-site maintenance.To access this data please refer to the Data Services Platform: <a class="external-link" href="https://environment.data.gov.uk/flood-monitoring/assets/demo/index.html#" rel="nofollow">Rainfall API demonstrator</a>For instructions on how to download the data as a CSV please refer to: <a class="external-link" href="https://environment.data.gov.uk/support/faqs/275878159/275878329" rel="nofollow">How to download Rainfall data as a CSV (excel)</a>For quality controlled and historic data please send your request to: <a class="external-link" href="mailto:enquiries@environment-agency.gov.uk" rel="nofollow">enquiries@environment-agency.gov.uk</a>

Rainfall data explained

Created : 23 October 2019 Updated : 20 February 2020Website developers can access our rainfall data through an Application Programming Interface (API). An API is a set of tools for building software applications. It provides the building blocks for developers to create an application or ‘web service’.We have approximately 1000 real time rain gauges which are connected by telemetry. Measurements of the amount of precipitation (mm) are captured in automatic rain gauges and reported back to use for operation decision making. The data reported here gives accumulated totals for each 15 minute period. The data is typically transferred once or twice a day but more frequently during heavy rainfall events.Please note the API is unvalidated data and could potentially contain errors due to faulty instruments or on-site maintenance.For quality controlled and historic data (more than 12 months) please send your request to: <a class="external-link" href="mailto:enquiries@environment-agency.gov.uk" rel="nofollow">enquiries@environment-agency.gov.uk</a> You can access the Rainfall API from the Data Services Platform homepage: <a class="external-link" href="https://environment.data.gov.uk/flood-monitoring/doc/rainfall" rel="nofollow">Environment Agency Rainfall API</a> We have developed a demonstrator which shows how to use the API: <a class="external-link" href="https://environment.data.gov.uk/flood-monitoring/assets/demo/index.html" rel="nofollow">Rainfall API Demonstrator</a>

Rainfall data - how to access API rainfall data

Created: 23 October 2019 Updated: 23 October 2019We only include our own gauges in the API feed. If you are interested in seeing our gauges, the Met Office gauges and others then we are working on putting our feed alongside the Met Office data on the Weather Observation Website (<a class="external-link" data-card-appearance="inline" href="http://wow.metoffice.gov.uk/" rel="nofollow">http://wow.metoffice.gov.uk/</a>) in the very near future.
