Monterey Peninsula Weather

California's infamous marine layer, but Big Sur experiences far more dramatic temperature shifts. The Peninsula remains locked in a cool, maritime gloom with fog hanging low over the beaches and average highs barely creeping past 62°F to 66°F.In contrast, while Big Sur’s rugged ocean cliffs can be socked in with thick, persistent summer fog, heading just a few miles inland into its redwood canyons or higher ridge elevations reveals bright, direct sunshine with temperatures soaring into the upper 70s to 80s°F.


In November, the dynamic completely flips: the marine layer fog dissipates, replaced by crisp, clear skies across both regions, making the ocean views on the Peninsula much sunnier and clearer than in summer. However, as late autumn brings shorter days and the onset of the winter rainy season, Big Sur's deep topography turns noticeably colder than the Peninsula—mornings in its valley bottoms can plunge into the 30s°F, and incoming storm fronts create sharp winds and early darkness along the cliffs, whereas Monterey and Carmel maintain a more tempered, mild coastal climate.
