Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Sunday’s high temperature reached 82 degrees in San Luis Obispo, which tied the record for Dec. 1 set in 1995. Sunday’s maximum temperatures along the beaches reached into the high 70s, with both Port San Luis and Los Osos hitting 78 degrees.
This morning’s gentle to moderate (8- to 18-mph) and at times gusty Santa Lucias (offshore) will produce clear, dry and cooler weather this morning. However, mild autumn temperatures are on tap this afternoon with most locations reaching the low to mid-70s.
A major change in the pattern is expected Tuesday morning as a dry cold front passes over the Central Coast with increasing clouds, but no rain.
This cold front will produce a steep pressure gradient along the shore that will produce moderate gale-force to fresh galeforce (32- to 46-mph) northwesterly winds along the coast Tuesday and Wednesday afternoon. Much cooler air behind this front will filter across San Luis Obispo County this week, producing cold conditions. The county will see maximum temperatures only reaching the low to mid-50s by Wednesday. Thursday and Friday will be the two coldest mornings with the North County dropping to the mid-20s with a hard freeze. The coastal valleys will drop to the low 30s with frost near the beaches.
Fair and slightly warmer weather is expected this weekend with some recovery from cold conditions. Next week looks dry and fair.
Today’s surf report
Strong to gale force (25-to 38-mph) northwesterly winds along the coast will generate a 4- to 6-foot northwesterly (315-degree deep-water) sea and swell (with a 5- to 13-second period) this afternoon through tonight.
Northwesterly winds will further increase Tuesday. Consequently, the northwesterly (315-degree deep-water) sea and swell will build to 8 to 10 feet (with a 5- to 9-second period) Tuesday afternoon and night. Rough indeed! This northwesterly (315-degree deep-water) sea and swell will decrease to 7 to 9 feet Wednesday.
A 3- to 5-foot northwesterly (315-degree deepwater) sea and swell (with a 5- to 8-second period) is forecast Thursday through Saturday.
Seawater temperatures will range between 57 and 59 degrees through Tuesday morning, then will rapidly decrease to 52 and 54 degrees later Tuesday and stay through Friday.
