Climate & Terroir
Maritime fog and Pacific breezes moderate temperatures along the coast, creating cool growing conditions; moving inland temperatures rise and diurnal shifts remain significant. Soils vary from sandy loam and marine sediments near the coast to calcareous, shale and alluvial mixes in upland and valley sites. Coastal ridges and river valleys create pronounced mesoclimates, allowing high-elevation and benchland vineyards as well as cooler slope plantings that emphasize acidity and varietal definition.
