September in Milltown: afternoons around 73°F, nights around 44°F. Nothing in the forecast averages argues against a doorstep delivery; any basket in the catalog travels well.
Heat (July). Afternoons average 85°F or more, peaking near 85°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, March, November and December). The average low reaches 20°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, March, November and December). About 50 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 (June and May). Around 2.6 and 2.3 inches of rain on average. Boxes are sealed, not waterproof: a covered porch or a workplace address keeps the packaging presentable.
