September in Clarkston: afternoons around 80°F, nights around 52°F. Nothing in the forecast averages argues against a doorstep delivery; any basket in the catalog travels well.
Heat (July and August). Afternoons average 85°F or more, peaking near 91°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.
Freezing nights (January, February and December). The average low reaches 30°F in December. Jams, sauces and fresh fruit should not spend a night outside; offices, senior residences and hospitals all receive indoors.
Snow (January, February and December). About 13 inches a year on average. Allow one extra business day when the date matters: a birthday box that ships two days out still lands on time if it leaves three days out.
Wettest months (May and April). Around 1.7 and 1.4 inches of rain on average. Boxes are sealed, not waterproof: a covered porch or a workplace address keeps the packaging presentable.
