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.
