Why we worry about tides...

[Prostar]

Don't get lost at Edmons UW park, wind up at the outside edge of the park, and have the tide swing on you because nobody checked before you got in the water. That was a loooong surface swim back in.

And here I thought Edmund's is an easy dive. At least that's what everyone is telling me. I guess we will find out in a couple of weeks. Going there on the 28th.

biggest tides in four years, 35 foot change.

You have GOT to be kidding!:11:

Early afternoon on the 28th should be fairly pleasant. The exchange is only 8 feet. Do check the tides and currents before you go, though.

... or just show up to the local dive site, look out over the water, realize you arrived at exactly the wrong time ...

"Hey, see the huge whirlpool out there?"

"Yup"

"Let's not get too close to that, mmmm'k?!"

"Sounds good"

...

Well the discussion when something like that

Anchorage is not really a good diving area, but here's some tides for the middle of May:

Here in salt water it is coming in or going out.

Tides do not come and go, they Ebb or Flood.

Hehe, on my last dive off of a boat in the San Juans, we got caught in a Maytag - separated from my buddy, surfaced, seeing him surface headed the opposite direction as me. Then we had divers surface all over, riding the rapids, with the boat spinning. Nothing like Cozumel. Water was a little cooler, too, but wow - the sights to see there.

14ft is nothing....

Heres one of my local dive areas:

(thats 10 metres not feet)
Thats about a 30ft+ range and not on a big spring either . Normal tidal range for that area.

Leads to big currents, amusing fun dive planning and like all of the UK, 99% of diving is "live boating" where you ascend under a dsmb.


Edit:- Or if you want to see even further up the river try Avonmouth docks where theres a range of approximately 14m (46ft). No diving that far up though. Its entirely mud.

FYI... I like using "Surfline" for weather forcasts prior to diving. Their LOLA model is also VERY good for looking a few days in advance at water conditions. You can also link to live web cams to "see" conditions at some beaches in your area. It sure would be cool if someone had something like this for diving...

And that differs from our usual dive brief how?
And thanks TSandM.
