An RNLI spokesman told Grimsby Live there was a danger for people who get too close to the waves.
“Over the last two or three days we have had particularly high tides. There has been spectacular wave action.
“Before Christmas, the tides brought in nine tonnes of debris. It’s also dangerous, because there’s not just water in the waves, but shells, stones and rocks. That’s enough to damage cars or unfortunately people get swept up in the water”. he said.
He added: “Depending on the direction and strength of the wind, there could be a power surge which could cause damage. If people want to watch it, they have to do so from a safe distance.”
The next high tides today will occur at 7:30 p.m. and are expected to exceed seven meters in height. The morning peak is expected around 8:15 a.m.
