Traditionally pilots have only booked swimmers onto neap tides. It has now become common practice to head out on a spring tide if the conditions are propitious. Spring tides are on the days inbetween the sets of neap tides.
Dover tidal heights are:
- Neaps tides - approximately 5.3 - 6.1 metres HW
- Spring tides - approximately 6.1 - 6.8 metres HW
