THE Surf Report- Early Edition


September no. October yes.

SURF:
I’m still perplexed on how bad/good the surf has been. September was absolutely dismal around here and then the past few weeks of October have been all-time. Think I’ll get into politics- that’s a lot easier to figure out. I think.


But before I get too far off track, let’s do a quick recap of the past week: Lots of good SW swell, NW swell, 100 degree temps at the beaches, and offshore winds. Pretty close to perfect except for the crowds and cool water temps. But I’ll take it. For tomorrow, the current SW/NW backs off but we still have chest high sets and clean conditions- beware the patchy fog though as our strong high pressure is finally starting to break down.


For Saturday it drops  to the waist high+ range but by Sunday we start to see new NW groundswell fill in. This was from a big storm in the Aleutians a few days ago and hopefully will light up Jaws and Mavericks this weekend. Unfortunately the angle is pretty N and it’s groundswell- which doesn’t filter through our islands all that well- but we still should have shoulder high sets late Sunday into Monday. Down in SD look for overhead sets.


Water temps are in the mid-60’s and tides this weekend are pretty mellow; 4’ at sunrise, down slightly to 3’ at lunch, and up to 4’ again at sunset.

FORECAST:
The NW mentioned above hangs around on Monday for shoulder high sets and then it slowly fades through the week. No real storms on the charts unfortunately for the 2nd half of next week.


Looks like we have some waist high SW headed our way next Thursday

and then maybe some better NW/SW around November 9th. But until then, nothing of significance. If anything changes between now and then, keep up to date on the waves and weather at Twitter/North County Surf. 

WEATHER:


Thankfully the strong Santa Ana winds never reached our coast, so fires were never really an issue this week. But we did have air temps in the 95 to 100 degree range and made it miserable for homeowners without AC (myself included).  High pressure has backed off slightly but we still have temps around 80 at the beaches this weekend and some patchy fog forming. Early next week we should be back to the low 70’s and low clouds/fog. Models are even hinting at showers next weekend. Yeah, right.

BEST BET:
Friday with leftover NW/SW or late Sunday/early Monday with new NW.

NEWS OF THE WEEK:


Rutgers University this month have concluded that explosive volcanic eruptions in the tropics can lead to El Niño events, those notorious warming periods in the Pacific Ocean with dramatic global impacts on the climate, according to a new study. Enormous eruptions trigger El Niño events by pumping millions of tons of sulfur dioxide into the stratosphere, which form a sulfuric acid cloud, reflecting solar radiation and reducing the average global surface temperature, according to the study co-authored by Alan Robock, a distinguished professor in the Department of Environmental Sciences at Rutgers University-New Brunswick. The study, published in Nature Communications, used sophisticated climate model simulations to show that El Niño tends to peak during the year after large volcanic eruptions like the one at Mount Pinatubo in the Philippines in 1991.

"We can't predict volcanic eruptions, but when the next one happens, we'll be able to do a much better job predicting the next several seasons, and before Pinatubo we really had no idea," said Robock, who has a doctorate in meteorology. "All we need is one number -- how much sulfur dioxide goes into the stratosphere -- and you can measure it with satellites the day after an eruption."


The El Niño Southern Oscillation (ENSO) is nature's leading mode of periodic climate variability. It features sea surface temperature anomalies in the central and eastern Pacific. ENSO events (consisting of El Niño or La Niña, a cooling period) unfold every three to seven years and usually peak at the end of the calendar year, causing worldwide impacts on the climate by altering atmospheric circulation, the study notes.

Strong El Niño events and wind shear typically suppress the development of hurricanes in the Atlantic Ocean, the National Oceanic and Atmospheric Administration says. But they can also lead to elevated sea levels and potentially damaging cold season nor'easters along the East Coast, among many other impacts.

Sea surface temperature data since 1882 document large El Niño-like patterns following four out of five big eruptions: Santa María (Guatemala) in October 1902, Mount Agung (Indonesia) in March 1963, El Chichón (Mexico) in April 1982 and Pinatubo in June 1991.

The study focused on the Mount Pinatubo eruption because it's the largest and best-documented tropical one in the modern technology period. It ejected about 20 million tons of sulfur dioxide, Robock said.


Cooling in tropical Africa after volcanic eruptions weakens the West African monsoon, and drives westerly wind anomalies near the equator over the western Pacific, the study says. The anomalies are amplified by air-sea interactions in the Pacific, favoring an El Niño-like response.

Climate model simulations show that Pinatubo-like eruptions tend to shorten La Niñas, lengthen El Niños and lead to unusual warming during neutral periods, the study says.

If there's a big volcanic eruption tomorrow, Robock said he could make predictions for seasonal temperatures, precipitation and the appearance of El Niño next winter.

"If you're a farmer and you're in a part of the world where El Niño or the lack of one determines how much rainfall you will get, you could make plans ahead of time for what crops to grow, based on the prediction for precipitation," he said.

Or in our case… the surf.
