Tehuantepecker going off right now

Recommended Posts

That's a bloody evil place if you're delivering down the coast to Panama.  Only two choices - go offshore and get pounded, or go up the beach and get sandblasted.

Or wait for a decent window... Most people sort of ignore/don't know about the Gulf of Papagayo, which while not as bad as Teuntepech, still is nasty. It is sort of visible in bottom right of the GRIB image above

Yes, waiting for a window is always the right choice.  But back in the day, getting through Panama, and bashing to Antigua for the owner's Christmas holiday was a highly pressured mission, so we had to just go with it.  Papagayo could surprise you similarly, as you say.  Bloody coast.

So does the Tehuantepec match up with So Cal's Santa Ana in timing and conditions?  It seems so......

Not really - the Tehuantepec is caused by High Pressure in the Gulf of Mexico. The pressure differential to the area of the Pacific on the other side is funneled through a gap in the mountains where you see the "wind fan".

Santa Ana wins are caused by High Pressure inland (Nevada I think). Same venturi effect with mountains though.

JackO',

The gulf of Tehuantepec experiences periodic wind events whereby it blows like a goddamn motherfucker for a couple of days at a time.  I mean REALLY windy.  Like Alenuihaha channel windy.   Blow the dogs of the chain windy.  Lash your car to a tree and go windsurfing with a water ski and 1972 necktie windy.

Just went through there over the weekend.  We stayed a few hundred yards off shore.  Yes we did see 45 knot winds but the seas were calm and it turned out to be a non event.

Having made several trips (5) through the area I've always stayed on the 10 fathom curve, this is away from any obstructions and near enough that there is no fetch.  Watch the wx map for a high in the Gulf of Mexico, if so wait a couple of days for it to dissipate before entering Tehuantepec. One trip we saw the wind go from 5 knots to gusts of 75 knots in less than 20 minutes.  We had steady 50 knots for about three hours before exiting to the south and wind dropping to 15 knots and then zero on the way to Panama.

As an Aussie sailing mate says, "Windy enough to blow Poms out of pubs."

I've traveled it twice, once in each direction. Not hard to see the weather patterns and just wait for a settled patch. We did it in December last year and Dec/Jan, while the worst months for them was uneventful for us.

The patient cruising sailor gets the best weather.

A handful of Pangeros disappear each year when caught offshore by a Tpecker (Papagayos do the same).  Two were rescued a few years ago about 850 miles offshore.  Most aren't.
