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.
