September in Geyserville: afternoons around 90°F, nights around 54°F. Chocolate and cheese are the two to route to an address where someone can bring the box straight in; cookie, nut, coffee and spa baskets shrug off an afternoon on the step.
Heat (June, July, August and September). Afternoons average 85°F or more, peaking near 94°F in July. Send chocolate, cheese and fresh fruit to a workplace or a front desk in these months; baked goods, nuts, coffee, tea and spa baskets can take a doorstep drop.
Wettest months (December and January). Around 8.8 and 8.1 inches of rain on average. Boxes are sealed, not waterproof: a covered porch or a workplace address keeps the packaging presentable.
