Montauk, New York is in USDA plant hardiness zone 7b. Its average last spring frost is around April 7 and the first fall frost around November 15, giving a growing season of about 222 days (NOAA 1991–2020 normals, 32°F, median). Start tender crops like tomatoes and peppers indoors weeks before the last frost and set them out afterward; sow hardy crops such as peas, spinach, and lettuce before it. The planner below turns those frost dates into a printable per-crop planting calendar.

Montauk planting calendar

Each crop's windows are counted from Montauk's average frost dates. hatched = start seeds indoors, solid green = plant out, teal = a fall sowing, and the terracotta dot marks the estimated first harvest. Ranges are extension-guide planning guidance, not guarantees.

Frost & freeze dates

From NOAA's 1991–2020 Climate Normals at station USW00054780. The median (p50) is the average date; the 90%-safe column is the date the freeze has passed in about 9 years out of 10 (p10 for spring, p90 for fall) — the conservative date to plant after or harvest before.

Freeze probabilities by temperature threshold (MM/DD, NOAA 1991–2020).
Threshold Last spring — avg Last spring — 90%-safe First fall — avg First fall — 90%-safe Season (days)
36°F Apr 23 May 6 Nov 4 Nov 17 194
32°F (freeze) Apr 7 Apr 20 Nov 15 Nov 29 222
28°F Mar 26 Apr 6 Nov 27 Dec 13 247
24°F Mar 13 Mar 29 Dec 9 Dec 29 272

32°F is the standard "freeze" line that damages tender crops; lighter 36°F frost can nip the most cold-sensitive plants, while hardy crops shrug off light frost down toward 28°F. Use the threshold that matches what you are protecting.

Growing degree days

Growing degree days (GDD) accumulate warmth above a base temperature over the year — a better predictor of crop development than the calendar alone. Warm-season crops need a long, warm GDD total; a short, cool GDD total favors greens and brassicas.

Model °F·days Used for

Base 40°F (cool-season) 5,436 cool-season crops (brassicas, greens)

Hardiness zone 7b

Montauk sits in USDA plant hardiness zone 7b on the 2023 map — meaning its average annual extreme minimum winter temperature is about 5 to 10 °F. That number tells you which perennials, shrubs, and trees reliably survive an average winter here; it does not set your planting dates, which come from the frost calendar above.

Frequently asked questions

What USDA hardiness zone is Montauk?
Montauk, New York is in USDA plant hardiness zone 7b on the 2023 map (average annual extreme minimum temperature 5 to 10 °F) — from the USDA Plant Hardiness Zone Map 2023, matched to this location's ZIP. See the methodology page for sources.
When is the last frost in Montauk?
The average (median) last spring frost at 32°F is around April 7, from NOAA's 1991–2020 climate normals at the nearest reporting station. Roughly one year in ten the last frost is as late as April 20, so wait until then before setting out frost-tender plants if you want to be safe.
When is the first fall frost in Montauk?
The average first fall frost at 32°F is around November 15. That leaves a growing season of about 222 days between the average last spring and first fall frosts.
When should I start tomatoes in Montauk?
Start tomato seeds indoors about Feb 10 – Feb 24 and transplant them outside about Apr 14 – Apr 21, once the danger of frost has passed. Estimated first harvest is around Jun 13 – Jul 3.
How long is the growing season in Montauk?
About 222 days at the 32°F threshold (NOAA 1991–2020, median) — the span between the average last spring frost (~April 7) and the average first fall frost (~November 15). Cold-hardy crops extend usable time at both ends; frost-tender crops fit inside it.
