SLO County weather forecast: Warm weather and no rain expected through end of April

The models indicate that the Central Coast will remain dry through the end of April. This condition is frequent; April saw no rain in 2021, 2013, and 2004.

Much like last week, storms will move through the Pacific Northwest. These low-pressure systems will produce a classic Central Coast spring weather pattern with areas of fog and mist during the night and morning, clearing during the afternoon as strong to gale-force (25 to 38 mph) northwesterly winds start on Sunday and continuing through Tuesday. Temperatures will reach between the high-70s to the low-80s in the inland valleys (Paso Robles), the mid-70s in the coastal valleys (San Luis Obispo), and the low-60s along the beaches on Sunday.

A trough of low pressure along the coastline will create gentle to moderate (8 to 18 mph) northwesterly to southwesterly winds on Wednesday into Friday. These onshore winds will allow a deep marine layer to develop along the coastline with pockets of fog and mist during the night and morning. Many beaches will remain overcast for most of the day.

The long-range models indicate a slight chance of southerly winds and rain on May 7 and 8.

Surf report

A 6- to 8-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) is expected along our coastline from Sunday into Tuesday.

A 4- to 6-foot northwesterly (290-degree, deep-water) swell (with an 8- to 10-second period) is expected on Wednesday, decreasing to 2- to 4-feet with the same period on Thursday into Friday.

Keep your thickest wetsuits available; seawater temperatures will range between 51 and 53 degrees through Wednesday, increasing to 53 to 54 degrees on Thursday into Friday.
