Pinnacles
Close to Monterey Bay on the map, but behind enough Coast Range to lose the ocean's air conditioning.
Pinnacles sits in the interior fold of the Coast Ranges. Marine air reaches Salinas easily but must cross ridges to reach the park, so summer afternoons behave much more like inland Paso Robles than coastal Monterey. Winter rain greens the slopes; summer removes almost all precipitation, heats the rock and drives a large day-to-night swing. Shade and aspect are real microclimates in the narrow canyons, not minor trail details.

The four seasons
THE PARK CHANGES VERTICALLY, TOOWinter
The green and wet season, with cool canyon bottoms and slippery rock after frontal rain.
Spring
Rapid warming and the last dependable rain; exposed slopes dry weeks before shaded canyons.
Summer
Very hot, nearly rainless and far less marine than the short distance to Monterey Bay suggests.
Autumn
Heat can persist into October, with the first Pacific front providing the real seasonal break.

What changes the day
CLIMATE CONTEXT · NOT A LIVE WARNING FEEDHeat
Exposed rock and limited shade amplify an already hot interior-valley afternoon.
Flash runoff
Steep, narrow drainages respond quickly when a winter front produces intense rain.
Dry fuels
Months without meaningful summer rain leave grass and chaparral fully cured by autumn.
