View Full Version : Supermoon Effecting Tides?

I've only been here 6 weeks but have never seen the tide as high as the last two days. Local news is blaming the supermoon eclipse. This was behind the place we're staying but I'm thinking this has been underwater before.

This was about 400' down the canal. Notice the concrete dock. No water stains on that dock.

As you come around the bend, the dock disappears under water

The Moon is in perigee or its closest to earth during the month. It is also the closest of the year, sometimes called proxigee.

When the moon is full or new, the sun and moon are in line which has a stronger influence on tidal activity. There are also other causes of high water along lower lying costal areas.

Wind will push water in and out of creeks and canals too.

Whenever the Moon, Earth and Sun are aligned, the gravitational pull of the sun adds to that of the moon causing maximum tides. Spring tides happen when the sun and moon are on the same side of the earth (New Moon) or when the sun and moon are on opposite sides of the earth (Full Moon).

Adding to what Jim said (all perfectly correct), constricted bodies of water will see the tidal effects more than open shore. When you have a large amount of water in an enclosed area (harbor, estuary, canal system, Puget Sound by Seattle) that is fed by smaller inlets (constricted harbor entrance, Strait of Juan de Fuca, etc...) the tidal rise and fall will be compounded and the tides will be higher and lower within these bodies than outside. The effect of this is what you observe.

The currents at the entrance points will also be stronger. I have sailed in the Strait of Juan de Fuca, where despite full sail and proper seamanship you couldn't make progress against the strong current. At maximum tiadal flow, you were forced to motor sail to make progress. Otherwise the best you can do is hold position.

I was surprised by the amount of current coming out of the Chesapeake Bay one morning. Wind was fairly strong out of the NE. We were making a good hauling ass 11 something through the water, but only 8 something over the ground. It seemed like it took an awfully long time to get to the Bay bridge after turning into the bay real early that morning headed to Annapolis. I didn't realize there would be that much current coming out of such a large body of water. We did turn in towards the South side, so it might not have been that strong on the other side.

I raced in SF Bay once in unusually light air (Prosail on a Hobie 21). We were headed against the current upwind, and the wind kept dropping. Everyone was going backwards, and we set the Kite since the apparent wind was stronger than the actual wind. We quickly assumed a gaining lead. The wind started filling back in, but unfortunately the race was called. If it's not blowing 20 knots out there, they don't think they have any wind at all.

Being new to here, I didn't think anything of it until someone on the local news mentioned it. It could have been based on fact or pure speculation. News is just entertainment today.

Talking to the locals, I have heard the water level in the canals is greatly affected by wind. Some saying in the winter wind speeds usually increase and come from the north. This drains a lot of water out of the canals making some of them too shallow for sailboats to navigate. But one guy who is in the dock business said at least once every winter the water level will rise to the top of the seawall.

To anyone who can't see the pics, they are in my album here under Misc.

I thought of another tidal current story. The same boat I helped deliver to Annapolis needed to come back South from Newport to Annapolis later the same year. The owner went with us for part of the way on that trip, and was a lot later getting to the boat to leave than we wanted. The plan was to come down the East River by Manhattan, but we wanted to avoid the strong current. We missed the timing waiting on the owner, so we were going through there at the worst time. Old maps show that area being named Hell. It was rough. I was on the helm motoring and with such currents and smooth seawalls, often the best place to be is as close to the wall as possible. All sails were down, and we were just motoring. It was a fancy 50 footer racing boat, so it moved well normally just under motor.

A woman was pushing a baby carriage in the same direction we were going right next to the railing on top of the sea wall. I was probably two feet from the seawall, and the lady pushing the baby carriage, walking at her normal slow pace, stayed probably 5 feet away from the boat for probably 15 or 20 minutes going the exact same speed we were while the current boiled waves right on the other side of us.

There are also other causes of high water along lower lying coastal areas.

The primary one, of course, being the gods are attempting to scare the bejeezus out of Julie as she tries to resolve her dilemma on buying the house.

Don't fold. Call their bluff.

I lived a year in a place with some of the larger tides on the planet. 7 meter (23ft) diurnal tides (i.e. twice a day in and out or change every 6 hrs 15 minutes).

We lived 3 miles offshore on our lil Island during spring tides & Inland on a sand spit among the mudflats at low tide!

You will never truly understand tides unless you live in a place with big tidal turnarounds.

Now its really gone.

In the distance is the mainland 3 miles away - theres no water left between us 3 miles offshore on our Island and the mainland 3 miles away.!

That was a typo, right? You meant, "Rum".

What I find interesting is when Charley blew through here in 2004, it was selective in it's damage, kind of like a tornado. Of course mobile homes took it on the chin but there were areas where three houses in a row ended up being demolished while all the other houses survived. One house just down the street from where we're buying was torn down and rebuilt on a Bob Vila series. A block away all the older houses are still there. Roof damage was about all they had.

But I'm still continuing my education about structures and how to beef them up for when the warm winds blow. :eek: And when I pass on to the Great Workshop in the sky, someone will buy the house, tear it down and build a small mansion in its place.
