WINTER SPRING SUMMER FALL WIN

🗺 Local Almanac — why this differs from a national chart

Last spring frost

~April 15 (UMD, central Maryland). Nothing tender goes out before this.

First fall frost

UMD's statewide default is Oct 31. But NOAA 1991–2020 normals put the median first 32°F at Nov 13 at the Annapolis waterfront station versus Oct 29 at BWI. Pasadena sits on Bodkin Neck between the Patapsco and the Bay, so it behaves like the waterfront station, not the airport.

The 10-hour wall

Growth nearly stops below ~10 hours of daylight. At 39.11°N that runs Nov 17 → Jan 26. Widely-quoted "early November" dates come from Johnny's farm in Maine, 5° further north — don't use them here.

Fall short-day factor

UMD says add 10–14 days to any seed-packet "days to maturity" for a fall planting. A 25-day radish is really 35–39 days in September.

Planting windows from UMD Extension's vegetable planting calendar and bulbs / herbs guidance. Frost normals from NOAA NCEI. Day length computed from NOAA solar equations for 39.11°N. Dates are for central Maryland and shift a few days earlier inland, later toward the water.
