What July feels like
July is rainless, so irrigation does all the work while the fog gives the vines a break overnight. Tasting rooms move guests outside early and indoors by two, and the whole valley learns to eat lunch in the shade.
Rain is genuinely rare — most years, July stays dry start to finish.
