High water – day 3

High water peaked at 13:10 today (2020.02.11) and at 406 cm, which is about 20 cm higher than yesterday. Today the weather was nicer so I was able to take more pictures. The sun was shining and there was no wind. The only waves were when a boat went by.

A high tide at 406 cm occurs roughly every 50 years. The highest astronomic high tide is 364 cm. Anything higher will be caused by weather, which at the moment has to do with an unusually low pressure storm off the coast of Norway. The low pressure pushes the ocean onto the shore creating higher tides than normal.

This picture was taken at 13:23 shortly after high water at Vangshylla on Tuesday, 11 February 2020.

The end of the breakwater was definitely under water, though the table and signs showed where there was something under the water.

The breakwater was dry until a boat went by and the boat’s wake broke over the top of the breakwater.

It was definitely uphill to get onto the dock.

Note that the left end of the ramp onto the dock is almost in the water. There may have been one or two centimeters of air between the ramp and the water.

The forecast is for high water to be a little less tomorrow, but still much higher than normal.

High water – day 2

High water topped at 12:30 today and 386 cm, so almost 20 cm higher than yesterday. Today there wasn’t so much wind, so no particular wave action on the breakwater. On the other hand, it was raining a lot and more difficult to get good pictures.

High tide at Vangshylla at 12:18 on 10 February 2020

Walking out to the boats was on a level, or perhaps slightly uphill.

I was surprised to see men out on the breakwater fishing. They were wading through the water and standing on the table. Two more fishermen arrived while I was taking pictures. I felt that it is a bit dangerous to be on the breakwater when the tide is so high and with more than four meters of water on the inside of the breakwater. I wonder if the fish bite better at high tide. I’m not an experienced fisher so I don’t have the answer to the question. My fishing is done in the freezer department in the food store.

Tomorrow the forecast is for the tide to be even higher still, and hopefully the weather is better to get even more pictures. I’m using data from www.kartverket.no/sehavnivå. The measurements are taken in Trondheim and adjusted for us living farther in the fjord. Time difference is calculated at 0 minutes and height difference at 1.04. It can be noted that the low tides are also 50-70 higher than the tide tables.

High water at Vangshylla

When the moon is full and there is a storm coming to the west coast of Norway, the tides can be higher than normal. This is the situation at the moment (Sunday, at 11:30 am).

The calculated high water at Vangshylla at 11:42 was for 322 cm, but the registered high water level was 368 cm at 11:40. So there is a difference of 46 cm. The forecast for the next few days is for even higher water levels both on Monday and Tuesday.

Our closest measuring station is at Trondheim, which is on the same fjord, but closer to the coast. There the calculated high water level was 309 cm and the registered high water level was 355 at 11:40, making a difference of 46 cm.

With the wind and the high tide, it isn’t safe to walk out on the molo today.

Not much clearance and the waves are breaking over the molo.

On Monday, the expected high water level is 381 cm at Trondheim and on Tuesday it is expected to be 398 cm.

At Vangshylla, the high water level on Monday is expected to be 393 cm and on Tuesday at 412 cm. It is going to be interesting to follow up the next two days when the highest tides are in the middle of the day.
