What Grows in San Pablo, New Mexico

The last hard freeze (28°F) in San Pablo typically lands around Feb 27, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Mar 20.

The first hard freeze (28°F) in San Pablo typically arrives around Nov 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 6, so the watching starts about Oct 21 — about 266 days after the spring freeze cleared.

Measured between 28°F hard freezes, San Pablo sees about 266 frost-free days — roughly Feb 27 through Nov 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 20 to Nov 6, about 231 days.

The federal record around San Pablo is a meaningful one — 570 documented sites, mostly Underground Storage Tanks entries (303), the nearest Underground Storage Tanks record about 0.8 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.

From about Oct 21 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Nov 20 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Nov 20. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
