AUGUST 1998 WEATHER SUMMARY
Two warm spells at the first of the month and again during the third week brought above average temps for prolonged periods. Highest temp was almost 80F on the 5th, culminating a 6 day run of above normal temps. However, we still did not have a single night where temps did not fall below 60F, and nighttime temps actually cooled off towards the end of the month, with a number of readings between 50-52F...not unheard of in isolated cases, but rarely in the number of days seen for this month. August/Sept/early Oct is our warmest season, and so far, as we enter our "Indian" summer period, temperatures are cooling down instead of warming up. Sea Surface temps are believed responsible, and some local readings north of the Golden Gate have been reported as low as 52F, although the generalized temps are still in the mid-50's. By this time of year, we normally have decreasing winds, fog is diminishing and becoming lower and shallower, and T'Storms are diminishing towards month's end but still a regular occurrence in the Sierra. This year, winds have remained near to slightly above normal, and surf has been up in response to some E Pacific tropical disturbances + influences from the first early lows invading from the Gulf of Alaska. We have seen the first of our annual Diablo winds as a result of high pressure building in back of these lows as they scoot to the north. So far, the track seems somewhat lower in latitude than normal and there is a slight southward dip in tracks as storms near the coast. NW winds were brief, but sometimes brisk, and there is a strange feeling of fall to the air..way to early for here. Humpback whales were still being seen from shore early, but in declining numbers by the middle part of the month..and none have been seen since the third week. Striper fishing remains good, although the great runs of July seem over, but lots of fish in the local troughs remain. Salmon are starting to move north, and it looks like they won't hit the beaches again this year - maybe only a dozen or so have been reportedly caught from the surf... and fishing on the pier, although wide open on a few occasions, has been inconstant, except for bass near the breakwater early and late. Bait fish have also moved out, and bird life is diminishing, but by no means absent.
