Harbour Access Times
If you wish to determine when you can get in or out of Pwllheli Harbour (or any other area where your draught may restrict the times at which you can enter or leave) you may find the following spreadsheet useful. The second sheet of the spreadsheet explains how to use it.
At New and Full Moons Pwllheli LW is 15:00 UTC ± 30 minutes
At First and Last Quarters Pwllheli LW is 08:00 UTC ± 60 minutes
All times are UTC
The following page shows the moon's phases for the next few years. Using interpolation this allows the approximate time of LW to be determined for any date within the covered period.
