Spring tides in Jersey go below predictions
Jersey has some of the highest tides in the world. This 2 minute video shows how fast the tide can rise during the third hour of the rising tide.
Filmed at Seymour Tower 10 March 2012. Low water was just 0.2m above chart datum (the zero calculation). This was about 30cm lower than predicted due to high pressure (1036mb) over Jersey. The high tide was 11.66m.
The result is that the tide needs to rise 11.46m in just 5 hours 36 minutes from low to high water. The Proudman tidal gauge for the 10th and 11th of March show just how far below the predicted low tide the sea actually reached.
We were staying overnight in Seymour Tower so there was no worry about being cut off and stranded.
However, I was running late and arrived at Seymour slip at 1705. By the time I reached the tower at 1735 the inshore gullies had filled behind me. It was like watching doors closing behind you.
I was therefore quite surprised to see a few people wandering back from the tower at 1715 with only a couple of minutes to spare before the inshore gullies started filling with water. It is worth noting that it is the gullies nearest to shore that fill first in this area.
This is a good reason why you should respect the tides around Jersey and be very careful once the tide starts to rise.
