The Irish coast experiences two high tides and two low tides in every 24 hour 50 minutes period. ‘Double tides’ are experienced only on the east coast in the Arklow area of South Wicklow and North Wexford. High water at Dublin occurs about 30 minutes before high water at Dover (UK). High water on the south and west coasts of Ireland occurs some 6 hours before Dublin. High water on spring tides at Dublin is at midday and midnight while high tides on springs along the south and west coasts are at 6 am and 6 pm approx. The height of spring tides varies from about 1 metre (3 feet) at Arklow to 5metres (16 feet) at Foynes and Galway.
