Lake of the Woods, California is in USDA plant hardiness zone 7b. Its average last spring frost is around April 15 and the first fall frost around November 26, giving a growing season of about 224 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.
Lake of the Woods planting calendar
Each crop's windows are counted from Lake of the Woods'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 USW00023187. 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 | May 5 | Jun 1 | Nov 7 | Dec 1 | 184 |
| 32°F (freeze) | Apr 15 | May 9 | Nov 26 | Dec 16 | 224 |
| 28°F | Mar 11 | Apr 17 | Dec 12 | Jan 22 | 275 |
| 24°F | Feb 3 | Mar 22 | Jan 1 | Feb 23 | 344 |
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) | 4,098 | standard warm-season base (tomato, corn, beans) |
| Base 40°F (cool-season) | 6,995 | cool-season crops (brassicas, greens) |
Hardiness zone 7b
Lake of the Woods 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 Lake of the Woods?
- Lake of the Woods, California 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 Lake of the Woods?
- The average (median) last spring frost at 32°F is around April 15, from NOAA's 1991–2020 climate normals at the nearest reporting station. Roughly one year in ten the last frost is as late as May 9, so wait until then before setting out frost-tender plants if you want to be safe.
- When is the first fall frost in Lake of the Woods?
- The average first fall frost at 32°F is around November 26. That leaves a growing season of about 224 days between the average last spring and first fall frosts.
- When should I start tomatoes in Lake of the Woods?
- Start tomato seeds indoors about Feb 18 – Mar 4 and transplant them outside about Apr 22 – Apr 29, once the danger of frost has passed. Estimated first harvest is around Jun 21 – Jul 11.
- How long is the growing season in Lake of the Woods?
- About 224 days at the 32°F threshold (NOAA 1991–2020, median) — the span between the average last spring frost (~April 15) and the average first fall frost (~November 26). 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 USW00023187 (Sandberg, 28.3 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.
