Weather forecast for week of Nov. 29 — Winds keep SLO County dry and clear
Like last week, the Eastern Pacific High off the California coastline will continue to block any low-pressure systems from approaching the Central Coast through this week. Consequently, dry weather will persist.
The night and morning Santa Lucia (northeasterly) winds will continue to produce clear skies with cold mornings (subfreezing) in the inland valleys and mild afternoons throughout San Luis Obispo and Santa Barbara counties as high pressure builds over Central California through Tuesday.
Persistent moderate to fresh (13 to 24 mph) northwesterly winds are forecast on Wednesday through Thursday which should allow marine low clouds with areas fog along to develop the coastline during the night and morning.
Clear skies will return by Friday as the offshore winds redevelop.
The long-range models are not showing any signs of rainfall through the second week of December. Any storm that does manage to break down the high-pressure ridge will be weak and likely produce little, if any rainfall.
Surf report
Sunday’s 4- to 6-foot northwesterly (305-degree, deep-water) swell (with an 8- to 15-second period) is forecast along our coastline through Monday morning. A 6- to 8-foot northwesterly (315-degree, deep-water) sea and swell (with a 5- to 18-second period) will arrive Monday afternoon and night, increasing to 7 to 9 feet (with 7- to 17-second period) on Tuesday.
A 961 mb storm with hurricane-force winds is forecast to develop in the Gulf of Alaska today. A very-long period northwesterly swell from this intense low-pressure system will reach the Central Coast on Wednesday at 5- to 7-feet (with a 22- to 25-second period), increasing to 7- to 9-feet (with an 18 to 20-second period) on Thursday into Friday.
Seawater temperatures will range between 53 and 55 degrees through Saturday.
