The Mersea Tide Guide: Plan Your Journey Safely

"Despite the ongoing march of development Mersea manages to retain some of its former island magic. At full moon and new moon the sea water slowly creeps over the mud onto the Strood causeway and Mersea becomes, for a while, truly an island, cut off from the mainland. When the tide covers the Strood we do not recommend you attempt to cross, as this could be dangerous for you and damage your vehicle and other peoples vehicles."

— West Mersea Town Council

 

High Tide Cutoff Heights

If the tide height is 5.00 metres and above, it will more than likely cover the Strood. In this case, we highly recommend allowing up to an hour and a half either side of the peak high tide time to get on or off the island safely. So, make sure you know your Mersea Island tide times. You can get these directly at the Mersea Island Strood Cam, or there are plenty of printed local tide tables available in local businesses to pick up around the island. You can also view the Strood causeway road conditions in real time on StroodCam.

​​​BASIC RULES TO REMEMBER

1. Your car is not a boat and it won't float.

2. You will put yourself and others in danger if you attempt to drive through the sea water.

3. Salt water is highly corrosive and is not good for your car's electrics.

4. Everyone can see you on StroodCam if you get stranded.

5. You will not be popular (please refer to point 4)
