If your business location is close to the seaside or you are otherwise nautically interested you may find the uk-tides WordPress plugin useful. Using information extracted from www.tidetimes.org.uk/ and/or tidetimes.co.uk it formats the data returned to show the times and heights of high and low tides for the current day.
This is achieved using the [bw_tides] shortcode. You use the tideurl= parameter to indicate which server you want to provide the data, specifying the port for the tidal information you require.
To improve performance the data returned from the Tide times websites are cached until midnight.
