Hochatown, Oklahoma is in USDA plant hardiness zone 8a. Its average last spring frost is around April 13 and the first fall frost around October 27, giving a growing season of about 196 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.
Hochatown planting calendar
Each crop's windows are counted from Hochatown'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 USC00340567. 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.
| Threshold | Last spring — avg | Last spring — 90%-safe | First fall — avg | First fall — 90%-safe | Season (days) |
|---|---|---|---|---|---|
| 36°F | Apr 23 | May 4 | Oct 17 | Oct 31 | 176 |
| 32°F (freeze) | Apr 13 | Apr 29 | Oct 27 | Nov 11 | 196 |
| 28°F | Apr 1 | Apr 19 | Nov 4 | Nov 21 | 217 |
| 24°F | Mar 16 | Apr 6 | Nov 15 | Dec 5 | 243 |
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 50°F (warm-season) | 4,671 | standard warm-season base (tomato, corn, beans) |
| Base 40°F (cool-season) | 7,495 | cool-season crops (brassicas, greens) |
Hardiness zone 8a
Hochatown sits in USDA plant hardiness zone 8a on the 2023 map — meaning its average annual extreme minimum winter temperature is about 10 to 15 °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 Hochatown?
- Hochatown, Oklahoma is in USDA plant hardiness zone 8a on the 2023 map (average annual extreme minimum temperature 10 to 15 °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 Hochatown?
- The average (median) last spring frost at 32°F is around April 13, 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 29, so wait until then before setting out frost-tender plants if you want to be safe.
- When is the first fall frost in Hochatown?
- The average first fall frost at 32°F is around October 27. That leaves a growing season of about 196 days between the average last spring and first fall frosts.
- When should I start tomatoes in Hochatown?
- Start tomato seeds indoors about Feb 16 – Mar 2 and transplant them outside about Apr 20 – Apr 27, once the danger of frost has passed. Estimated first harvest is around Jun 19 – Jul 9.
- How long is the growing season in Hochatown?
- About 196 days at the 32°F threshold (NOAA 1991–2020, median) — the span between the average last spring frost (~April 13) and the average first fall frost (~October 27). Cold-hardy crops extend usable time at both ends; frost-tender crops fit inside it.

Frost, freeze, growing-season, and growing-degree-day figures are NOAA NCEI U.S. Climate Normals 1991–2020 for station USC00340567 (Battiest, 26.3 km away). The hardiness zone is the USDA Plant Hardiness Zone Map 2023, matched to this location's ZIP. Planting windows are computed by counting from the average last and first frost using per-crop offsets synthesized from U.S. Cooperative Extension guides — the full method and citations are on the methodology page.
