What August feels like
Late August is when the earliest sparkling fruit gets picked, usually at night under floodlights, which is worth staying up for once. It is fire-season weather too, and every local watches the ridgelines when the wind gets up.
Rain is genuinely rare — most years, August stays dry start to finish.
