These tidal predictions are NOT accurate, as they are currently based on too little data. As an indication, they probably get times right to within half an hour or so. Hopefully, that'll improve in the future. As such, they are supplied for planning purposes only, not for navigation. More accurate information for HOLYHEAD may be found at the UKHO's EasyTide website.
Predictions are based on Environment Agency tide gauge data from the real-time data API (Beta) : public sector information licensed under the Open Government Licence v3.0
Predictions made using Wesley Bowman's python implementation of UTide.
