Wave and tide data are measured using a Rosemount WaveRadar Rex, located on Swanage Pier, by kind permission of the Pier owners. The Rex was installed on 7 March 2007.
The OMC meteorological station was installed together with the WaveRadar on 7 March 2007. On 16 July 2024 the meteorological station was overhauled and the original OMC sensors were replaced with a MaxiMet GMX600.
| 25/07/2025 | To reduce data spiking, the maximum measurement range was reduced from the default setting to 10 metres. |
| 20/05/2025 | Scheduled service |
