September in Mount Horeb: afternoons around 73°F, nights around 52°F. Nothing in the forecast averages argues against a doorstep delivery; any basket in the catalog travels well.
Freezing nights (January, February, March, November and December). The average low reaches 10°F in January. 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 39 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 July). Around 5.5 and 4.7 inches of rain on average. Boxes are sealed, not waterproof: a covered porch or a workplace address keeps the packaging presentable.
Weather only matters for the shipped box. The same-day flowers on this page are carried in by a local florist and handed over, whatever the month.
