Something Brewing in the South Pacific - Part 2

Things are still looking pretty good for this newly forming storm that is going to be sending some large S-SW surf for South America and Central America...and some decent sized waves for Mexico, Baja, and Southern California

The storm has actually just started the key portion of its development, where the colder low-pressure near Antarctica mixes with a warm/wet low-pressure from the mid-latitudes. Over the next couple of days the latent-heat energy of the warm air will be released as it cools in the colder low-pressure...this will help to supercharge wind speeds...and hopefully mean that we will get bigger surf down the road.

Here is a chart that shows a lot of it happening.




Here is a shot from the Quikscat satellite showing increasing wind speeds in the good part of the storms core.



And finally here is a shot of the WWIII swell model, which is showing the dominant swell period...as you can see it has the new S-SW swell moving into Central America and Southern Mexico on the 18th, and that it will start showing in Baja on the 19th and finally arrive in SoCal on the 20th.



The storm still has some developing to do before we get concrete wave heights for SoCal but at this point it does look like the S facing spots will be around head high while the standout S facing standouts see some overhead sets, which sounds good to me after all of the flatness we have see over the last few days.

Something brewing in the South Pacific…(hmmm anyone feel like a Mexico/Central America/South America surf trip.)

While I am not quite ready to issue a swell alert for this storm I am definitely keeping a close eye on it as it develops.

Check out this animation and you can see what I mean (you may have to refresh the page to get the .gif to start playing from the beginning.)



As you can see there is a tight little nugget of a storm brewing up in the upper latitudes of the SPAC right near the Antarctic ice…what is really interesting is that the forecasts are showing the storm making a very solid shift from the upper to the mid-latitudes and that a lot of this movement is being powered by an infusion of warmer air/water-vapor that is being pushed down from tropical waters. It looks like this warmer air-mass is going to help supercharge the colder storm making it way more intense than it would have been on its own.

Forecasts are showing a great movement track for this storm…moving across the latitudes gives it a lot of extra time to generate waves and lines up a lot intense fetch for South America and Central America.

Also because of its movement the backside of the storm, that is being pushed by a ridge of high-pressure to the west, lines up fetch for Mainland Mexico, Baja Mexico, and Southern California. Check out this chart and you can see what I mean.



At first glance…and I will likely revise this as the storm actually forms in the next 3-4 days…this is what I see for each region.

South America is definitely going to be the biggest out of all of the areas affected by this swell…looks like Chile could be a little wet and wild as the storm itself pushes over about they same time the swell does. Peru looks like it could be a pretty good call if you are looking for some serious sized surf.

Central America will also get a good dose of swell…there may be a bit of blockage from the Galapagos Islands for the southern areas (Panama and Southern Costa Rica) but even the more shadowed spots will see consistent well-overhead+ surf from this one.

Mainland Mexico will also be well exposed to this swell…the further south you are the bigger it will be…expect to lose a lot of size as you move up the coast towards Baja.

Baja and SoCal will both likely see some decent sized surf from this storm as well but it is still a little spotty on exactly how much energy it will be able to send our way before it shifts out of our swell window. At this point I am expecting the swell to arrive in Southern Baja around the 19-20th and more on the 20-21st for SoCal.

Making Travel Plans

This storm has been a pretty consistent feature in the forecast for the last several days…so I am inclined to say that this may be a good time to roll the dice on a trip to Central America or Peru. The swell isn’t 100% locked in at this point but I think the odds are good that it will pull together over the next few days. If you are thinking about making travel plans to those areas I would try and give yourself a little fudge room on your dates…try get to Peru by the 15th and to Central America by the 16-17th...and then plan on the swell arriving a day or so after you get to your spots.
