THE Surf Report- Early Edition



Winter called and wants 1 more chance.  

SURF:
Seems like all the talk around town lately has been the lack of solid surf since January. Walls must have ears because Ol’ Man Winter just called and says we should give him 1 more chance. Sound like a deal? Good. Because we have wet weather and waves on the way. 


First up, let’s review the week that wasn’t. Small SW showed up late Tuesday and has given us chest high sets in far north county SD and shoulder high waves at best OC spots. That lasts through tomorrow then drops Saturday. 


Now switching back to winter mode- new WNW should start to fill in Saturday evening for shoulder high sets Sunday morning (especially towards SD). We also have a weak cold front coming through that will kick up our winds on Saturday/Sunday; so the building surf may be bumpy. 


Water temps are in the high 50’s due to all our N winds and tides this weekend are 3’ at sunrise, down to 0’ at lunch, and up to 3’ at sunset. Make sure to keep up to date on the waves and weather at Twitter/North County Surf. 

FORECAST:


You know that new step-up I bought at the end of January that hasn’t been waxed yet? It’s time to wax it. JINX! Don’t worry- I just knocked on wood. We’re all good. As mentioned above, winter seems to be making a return- about 3 months late. But beggars can’t be choosers and I’m fired up. First is the lingering WNW over the weekend that will give us leftover shoulder high sets on Monday morning. Tuesday drops to the waist high+ range then we get another building WNW on Wednesday afternoon for shoulder high waves again. 


Now here’s the good part: Things kick up a notch on Thursday for head high (and dare I say overhead sets late Thursday?! Don’t worry- I just knocked on wood again). Then things get really interesting. Finally. Another cold front may move through late Thursday into Friday and along with it- peaking WNW swell on Friday for 10’ sets. Step-up time! Now it could be bumpy from the cold front but I really don’t care. I’m just so happy to see waves bigger than Kelly’s Surf Ranch. I may just have to sell that property I recently bought in Lemoore. 


After that, the forecast charts don’t show the Aleutians slowing down and we may get another overhead WNW again around the 15th. I think it’s time to activate the Emergency Boardriding System! (I trademarked that- don’t use it).

WEATHER:


Been cool the past few days. That looks to be the case the next few days along with a chance of showers late Saturday into Sunday morning. Once that blows through, we’ll have nice conditions and temps in the mid to high 60’s Monday through Wednesday. And If the models are correct, we could have a better chance of rain for next Thursday into Friday. And if that swell materializes for the 15th- we may have showers again. What’s the old saying? April showers bring May flowers? Looks to be true.  

BEST BET:
If you like a little wind with your waves, then you’ll love late Saturday/Sunday, next Thursday/Friday, and maybe late next weekend!

NEWS OF THE WEEK:
I know it sounds funny to talk about the end of winter since we have showers potentially coming the next 7 days and Nor-Cal is about to get pummeled tomorrow, but technically winter ended March 20th so I thought it was a good time to have a look in the rearview mirror and recap our ‘rainy’ season. With help from the Climate Prediction Center (CPC), here’s how we fared across the US and Southern California:


Winter was much warmer than average across northern, central and western Alaska, the southeast and southwestern (us) parts of the country, while the High Plains, parts of the Pacific Northwest, southeastern Alaska, and southern Texas experienced below normal temperatures. Elsewhere, temperatures were around average.


The western (us) and southeastern regions of the United States observed a drier-than-average winter, while the Missouri and Ohio River Valleys, Great Lakes and western High Plains recorded a wetter than average winter. Based on the early season prediction last fall, the outcome was pretty accurate by the CPC.



What actually happened this winter then with the above average temps in So-Cal and below average rain? La Niña? Other stuff? Lots of things actually. For one, there has been a La Niña active over the Pacific Ocean. And has been covered numerous times in THE Surf Report, La Niña can influence the winter over the United States by impacting the jet stream and the placement of high and low pressures over the mid-latitudes. But we can’t blame EVERYTHING on La Niña…

Also active during this winter was the Madden Julian Oscillation (MJO). The MJO is the major fluctuation in tropical weather on weekly to monthly timescales. The MJO can be characterized as an eastward moving 'pulse' of cloud and rainfall near the equator that typically recurs every 30 to 60 days. In short, as the MJO moved around the globe, it led to prolonged periods of colder and warmer than average temperatures across much of the country this winter. Though, while this certainly impacted monthly climate, it likely had less impact on climate patterns averaged over the entire winter. Anything else, you ask? Well, there was always the randomness of the weather as well as variability in other atmospheric oscillations like the Arctic Oscillation (that’s another story).

But why is La Niña / El Niño (ENSO) so influential on our weather? Basically it’s the one influence that is actually predictable a season ahead of time. We know that other things will impact the winter temperature and precipitation patterns besides ENSO. But we don’t know exactly HOW those other atmospheric features will behave more than a couple weeks in advance. In contrast, we usually know what phase it will be—El Niño or La Niña—months in advance. The other things mentioned, like the MJO or other patterns of middle to high latitude variability, are much more random, which means they don’t give forecasters nearly as much of a heads up.

As noted in the March 2nd THE Surf Report, our ‘rainy’ season turned out to be a dud. Even with showers forecasted this weekend, it will only be a drop in the bucket. So where do we stand as of today?...
• Newport 2.66” of rain (22% of normal)
• Oceanside 4.68” (39% of normal)
• San Diego at 3.18” (34% of normal)


Pretty ugly. But let’s forget about that. Winter is behind us and we can look forward to nicer weather. What is the Climate Prediction Center’s forecast for the next 90 days? First up, La Niña looks to be gone and we’re in a neutral state (i.e. normal). That should mean an average spring/summer for surf and water temps. As far as precipitation and air temperatures go for you landlubbers out there, we look to be high and dry with a below average chance of any significant rain and slightly above air temps (nothing new there). So basically this spring will feel like an early start to summer. Which I guess means our past winter (and it’s lack of rain) was really our spring!

(On a side note, I hope you read last week’s THE Surf Report in regards to tsunami’s since we had a 5.3 earthquake off the Channel Islands today. Damn I’m good).

PIC OF THE WEEK:


Now that Mick’s retired, he’ll be hunting down set ups like this. Think he needs a board caddy? Will work for surf.

Keep Surfing,
