JUNE 1999 MONTHLY REVIEW

Just like last year,  June was the month of transition of  the basic climatology. Whether it be from El Nina to La Nina conditions, like last year, or the transition from La Nina to more historically typical summer weather, June seems to be the month when we transition from the dominant influence  of the Gulf of Alaska systems to the more local effect of thermal lows pulling cool ocean air inland. I use a truly subjective scale reading of 70F  as my benchmark for when my house is under minimal sea induced onshore flows, and warm sunshine is present. Cool marine air, if shallow enough or when offshores are happening, have  a tough time penetrating to my house, nestled in the coastal hills three miles inland. After starting the month just like the previous 8 weeks or so, with a minor rain event (very heavy drizzle/light rain), low 50 temps, continued stiff onshore winds and SST's under 50, we evolved into a prolonged period of offshore winds with 8 out of the last 9 days well over 70, peaking at 83 on the 30th. Perhaps not coiincidentally, around the middle of the month, SST's finally started to significantlly warm up. Local SST is now 52, which is a rise of almost 4 degrees over the last 6-7 weeks. Bait fish are starting to show in good numbers along the coastline, but very rough water has minimized fishing. Some Salmon have been reported being caught on the pier and a report from Rockaway with bait been pushed onshore and 1 Salmon caught. Some other scattered fish have been reported, but not even the bait fisherman have had much success. Overall, the surf fishing was one of the worst in memory, or at least the last 20 year or so. Those of us with longer memories can remember that Striper and Salmon fishing in the surf traditionally opened up around the 4th of July, instead of the May/June openers typical of the last two decades. In many ways, the "feel" of this infant summer is much more typical of my youth in the 50's-70's than the 80's and 90's.
