Tide times and moon phases for Royal Yacht Squadron. 13-day tide calendar showing high and low tide times, spring and neap tides for winging, sailing, and windsurfing.
What tide to launch at Royal Yacht Squadron
Launching at Royal Yacht Squadron is highly dependent on the state of the tide. Royal Yacht Squadron is classified as a double-tide spot, meaning the ideal session window is typically High tide ±2 hours (extended window from double high). Outside of this window, riders may face expansive mudflats or shallow areas. Understanding these local nuances is the difference between a great flight and a long walk with heavy gear.
Double high tides at Poole Harbour
Royal Yacht Squadron uses tidal data from PORTSMOUTH, which experiences a double high tide—two high waters close together with a slight dip between them. This creates an extended window of deep water, ideal for winging and sailing. The 24-hour graph below shows the characteristic double-peak curve. Use the calendar to plan sessions around either high water.
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 Royal Yacht Squadron are derived from the nearest primary tidal station at PORTSMOUTH, located 13.4km 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 Royal Yacht Squadron can diverge from the readings at PORTSMOUTH due to coastal topography, shelving, and estuary flow.

Wind and weather forecasts for Royal Yacht Squadron are provided to help you plan your sessions. Conditions at this coastal location can change quickly, so always check the actual conditions when you arrive and trust your judgment. These forecasts are for recreational planning—always prioritize safety and verify conditions yourself before heading out. Tidal predictions for Royal Yacht Squadron are based on the nearest primary station at PORTSMOUTH (13.4km away). Local conditions can vary from these predictions due to coastal topography and weather effects.
