Preparing for SLO Weather on Your Trip

Planning a trip to SLO? Go ahead–pack light. Around here, the weather is as easygoing as we are.

The daily temperature in San Luis Obispo averages 70 degrees. In other words, perfect summer weather, even heading into traditionally colder months. Bring along light, breathable clothing and comfortable footwear–maybe even a swimsuit if you plan to go beach tasting in summer.

While days can range from cool to hot, nights in San Luis Obispo tend to be chilly year-round. A jacket is all you’ll need for a night out in summer, and in winter you may want to add a sweater. You definitely won’t want to pack any heavy winter coats or snow boots.

Average Weather in San Luis Obispo

At just 233 feet above sea level, San Luis Obispo’s climate is warm and Mediterranean. Winters lean mild and summers are sunny, though our proximity to the Pacific Ocean can make mornings a little foggy. (Don’t worry–it tends to clear up around noon.) Rain is scarce and we haven’t seen measurable snowfall since the late 1800s, so leave your umbrella and boots at home.

Bottom line: we keep it mild. No icy winters or blistering summers–just sunshine, breezy days, and refreshing morning mists.

Plan Your Activities Based on Average Weather in SLO

Though San Luis Obispo weather is mild year-round, there are some season-specific outdoor activities you’ll want to prepare and pack for, depending on your plans.

Winter is SLO’s rainiest season, though that’s still only 50 days of precipitation on average. Escape to sunny days here, especially if your home state is prone to blizzards.

Spring is wildflower season. Winter precipitation makes the region lush and green. Go for a hike or bike ride for the best views of rolling hills popping with color.

Summer is the best time to go beach tasting. Soak up the sunshine and wind down with a glass of locally bottled wine in cool vineyards at the end of the day.

Fall is harvest season. Surrounded by farms, it’s the perfect time to pick produce, go for hay rides, peep autumn colors on all-day hikes and bite into the goodness of the SLO life.
