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.
