JULY 1998 MONTHLY REVIEW
After the much below June temps and early rains, July was a much more typical
month, with no wild temp fluctuations or extremes, and no rain to speak of
other than local drizzle. Water temps have stabilized and are running very
near normal at 55-57F. Onshore winds occurred everyday this month, and no
day saw high temps above 72F or low temps above 59F. Fog, while present,
was generally on the light side, and light winds on the ocean were the rule.
Surf, as expected, also calmed down, and swells were consistently only 4-6'
with some days almost dead calm and surf <2'. Pockets of warm water still
remain offshore, and the unusual Albacore fishing has continued, with many
Blues still being caught close to shore between Monterey and Bolinas. In
a rarely (if ever) seen display, Humpback whales by the dozens are being
seen daily from the local beaches feeding and breaching in gigantic
splashes...oftentimes only 1/2 mile offshore. Other younger calves are closer
to shore, and have been spotted checking out the end of the Pacifica Pier.
A large number of Blue whales, the largest creatures ever to live, have also
become regular visitors to the Farralon Islands, only 25 miles offshore of
San Francisco. La Nina has become well defined in the Central Pacific,
and easterly trade winds have intensified. This pattern often results in
lower than normal tropical moisture running over the Sierra's causing T Storms.
So far, the monsoon season seems weak and somewhat later than normal. Summer
tree foliage and fruits are down..a lingering result of the cool, damp weather
of spring and early summer-a prime time for early season growth and bud setting.
