Pismo Beach Ocean / Surf Report
May 13, 2022
SEA/SWELL:
A 6- to 8-foot northwesterly (310-degree, deep-water) sea
and swell (with a 5- to 11-second period) will develop this
afternoon and remain at this level through Monday morning,
increasing to 7- to 9-feet on Monday afternoon through
through Tuesday morning.
An 8- to 10-foot northwesterly (310-degree, deep-water) sea
and swell (with a 5- to 11-second period) will start Tuesday
afternoon and will continue at this level through next Friday.
ATMOSPHERIC CONDITIONS:
Increasing high pressure and gusty Santa Lucia (northeasterly)
winds have produced mild temperatures throughout the Central
Coast this morning. At 3 a.m. Port San Luis reported 64
degrees.
In fact, these Santa Lucia (northeasterly) winds will build
to fresh to strong (19 to 31 mph with gusts to 40 mph) levels
this morning.
Today’s high temperatures will reach the high-80s in the
inland valleys (Paso Robles) and low-80s in the coastal
valleys (San Luis Obispo). The shoreline will range from
the mid-60s along the northwesterly facing beaches (Morro
Bay and Los Osos), while the southerly facing beaches
(Cayucos, Avila Beach and Shell Beach) the low-70s.
A pattern of strong to gale-force (25 to 38 mph with gusts
to 45 mph) northwesterly winds during the afternoon along
the coastline, decreasing and shifting out of northeast
(offshore) during the night and morning will start this
afternoon and will continue through Saturday morning.
These offshore winds will keep the marine low clouds
out to sea.
A warming trend will continue into the weekend as high
pressure builds over Central California. Away from the
Pacific Ocean, temperatures will warm to the mid-90s in
the Inland valleys and mid-80s in the coastal valleys.
Persistent northwesterly (onshore) winds will develop Saturday
afternoon into Monday morning. This onshore flow will allow the
marine layer to redevelop in the coastal regions with night
and morning fog and mist.
The northwesterly winds are forecast to increase to moderate
gale-force to fresh gale-force (32 to 46 mph) levels on Monday
afternoon into Thursday. These winds should be strong enough
to mix out the marine layer, leaving behind mostly clear
skies and seasonal temperatures.
