Pinnacles National Park

Around 23 million years ago, a series of volcanic eruptions shaped the landscape that is now Pinnacles National Park. The remnants of these ancient eruptions have formed a striking terrain of rocky spires and deep canyons. Visitors can explore diverse environments, from chaparral and oak woodlands to the cool, shaded depths of canyon floors.

Weather & conditions

Pinnacles National Park has a Mediterranean climate with hot, dry summers, and mild winters with moderate precipitation. The park is several miles inland from the Pacific Ocean. A wider variation in seasonal temperatures can be expected in the local area. Summers are hot with temperatures above 100 degrees. Winters are cooler with highs in the 60s. Big swings in temperature occur between day and night, year round.

What this latitude gives you

From 36.5° north, anything above declination +53.5° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -53.5° never clears the horizon at all.

Astronomical darkness lasts through every night of the year here, including midsummer, which makes this a rare site for a June or July imaging trip.

We do not hold a measured Bortle class for this site, so treat the sky as unknown until you have taken a reading of your own.
