Paso Robles Weather

Paso Robles Weather


San Luis Obispo County has diverse weather and climate zones that can vary by 30 or more degrees. When the coast is cold and foggy, the inland areas can be hot and dry. The difference can be as much as 50 degrees. An inland city, 24 miles from the coast, Paso Robles sits east of the Santa Lucia Mountain range, protected somewhat from the cooling winds of the Pacific Ocean to the west. Summers here are long, dry and extremely hot. During July and August, temperatures in northern San Luis Obispo county can reach triple digits, even climbing as high as 110 degrees or more. The record high temperature here was set in August 1933, at 117 degrees Fahrenheit. The super hot weather is referred to as “Fair Weather,” which generally comes with the approach of the California Mid State Fair. But even summer evenings cool down with gentle, rising breezes.

While the summer days can get excessively hot, the winters can and do get icy cold at night, frequently dipping below freezing from November into February and even sometimes into early March. Those lows can even sporadically reach into the teens. The record low temp was set in January 1913 at 0 degrees Fahrenheit. As cold as it gets at times, snowfall has only been recorded on two days : four inches of snow on both April 5, 1929 and December 15, 1989. Rain fall averages 15 inches per year and falls on approximately 47 days.

The climate in Paso Robles does however make great wine. With a long, mild fall and sometimes earlier than usual spring and long, hot summers, crops such as wine grapes, olives and nut trees, like almonds thrive here. Spring also brings an amazing abundance of wildflowers from March to June. Shooting stars, California poppies, lupines, and Mariposa lilies cover the meadows and rolling hills between the outlying wineries until the cycle begins again and summer’s relentless heat burnishes the breathtaking rainbows of the undulating hills, turning them to gold.
