How to Read Tide Tables
Tide tables show high and low water times throughout the day. Key terms to understand:
- High Tide (HW): When the sea is at its highest point. Less exposed sand.
- Low Tide (LW): When the sea recedes. More beaches are exposed.
- Tidal Range: The difference in height between high and low tide.
- Spring Tides: Extra-high and extra-low tides (great for rockpooling).
- Neap Tides: Smaller tidal changes (more predictable beach coverage).
Tides in Cornwall follow a semidiurnal cycle, meaning two high and two low tides each day.
