Water temperature data is recorded every 15 minutes and the graph is updated hourly. The reporting system is currently in the testing phase, so please be patient if any problems are encountered. If the page does not load, it is generally out with our control, but we will investigate and try to resolve where possible. The graph can take up to 10 seconds to load. There is a hosting cost linked to usage levels, so please try to limit the number of viewing instances each day. If unsustainable levels of viewing start to occur, we may have to revert to a non-interactive graph that is updated a few times each day while we investigate a different solution.
