The Pacific Ocean has a strong influence on weather conditions. Springtime visitors to Cabrillo National Monument should be prepared for cool, windy, and foggy conditions, even if it is sunny, hot, and dry further inland. An overcast marine layer can develop near the coast at any time of year, but this phenomenon is most common during the late spring and early summer. Locals call these times "May Gray" and "June Gloom." Thinking of hitting San Diego's beaches to laze in the warmth of sun-baked sand? You'll probably want to trade the swimsuit for a sweatshirt and pants, as cloudy skies dominate and temperatures rarely rise above 70 degrees. The upside: you can pack away the umbrellas, because there's little chance of rain.


Ahhhh, summer in San Diego. Blissful visitors stroll the park, the air redolent with the scent of sunscreen. The city enjoys temperatures in the 80s during July and August, but fog can roll in suddenly, resulting in a quick drop in temperature.


Following the rhythm of the seasons, San Diego begins winding down in autumn. Rain is rare, skies are clear, and temperatures usually hover in the mid-70s. Fall is also the time when Santa Ana winds hit the county. These ferocious winds howl in from the desert to the east, bringing dramatic temperature increases (daytime highs can quickly rise into the 90s), hot, dry air, and virtually no humidity.


November through February is the rainy season here, with chilly weather fronts roaring down from the Gulf of Alaska, delivering sometimes torrential downpours and temperatures in the 50s and 60s. Once storms move out, however, the views from Cabrillo are usually the best of the year: the rain cleanses the air and makes for crystal-clear panoramas.

What to Wear

A well-prepared visitor to Cabrillo National Monument will dress in layers any time of year to accommodate changes in weather conditions, and will remember the sunscreen and hat for sunny days: coastal sun can be bright, even on cold winter days.

Snow on San Diego's mountains
Winter is a great time to visit Cabrillo National Monument: once storms pass, the sun comes out, the air is clear, and the vistas can be spectacular.

Bayside Trail Slide Area
The same precipitation that creates crystal-clear views can also have adverse effects.  What happens when you get a lot of rain in a short period of time, combined with a typically arid Mediterranean climate?  When the soil is dry and there's no where for the water to go, you get problems - like this landslide on the park's Bayside Trail, which was triggered by heavy rains in 2005.
