Tide times and moon phases for Porth Ceiriad, Gwynedd. 13-day tide calendar showing high and low tide times, spring and neap tides for winging, sailing, and windsurfing.
What tide to launch at Porth Ceiriad
Launching at Porth Ceiriad is highly dependent on the state of the tide. Porth Ceiriad is classified as a low-water spot, meaning the ideal session window is typically Low tide ±2 hours. Outside of this window, riders may face exposed rocky reefs or shallow areas. Understanding these local nuances is the difference between a great flight and a long walk with heavy gear.
Spring vs. Neap Dynamics
Beyond daily high and low water, pay close attention to the tidal range. During Spring tides (following a New or Full Moon), the water moves faster and the range is greater, which can significantly increase currents. Conversely, Neap tides offer a smaller range and more stable water levels. Our calendar integrates moon phase data to help you identify these cycles well in advance.
How are these tides calculated? Our tidal predictions for Porth Ceiriad are derived from the nearest primary tidal station at Porth Ysgaden, located 15.43km from the main launch point. KnotNow uses historical harmonic data and scientific algorithms to predict water levels. Please note that these astronomical predictions do not account for "meteorological surges" - strong winds or extreme barometric pressure can cause the actual water level to be higher or lower than forecasted.
Why do local conditions sometimes differ? Tide conditions at Porth Ceiriad can diverge from the readings at Porth Ysgaden due to coastal topography, shelving, and estuary flow.
