Frost dates for Richmond, Virginia
Virginia · first & last freeze, from NOAA 1991–2020 climate normals
In a typical year, the last spring freeze around Richmond comes near April 3 and the first fall freeze near November 4. One year in ten, a freeze still arrives after April 18 in spring — and one year in ten, the first fall freeze has already landed by October 23. NCEI's own growing-season statistic (days between freezes, percentiled per year) puts the median at 215 days.
Freeze-date probabilities, three thresholds
| Threshold | Last spring — 9 in 10 years past by | Last spring — typical (median) | Last spring — 1 in 10 years later than | First fall — 1 in 10 years by | First fall — typical (median) | First fall — 9 in 10 years by |
|---|---|---|---|---|---|---|
| 36°F — near-freezing (frost can occur) | March 31 | April 16 | May 3 | October 14 | October 26 | November 6 |
| 32°F — freezing | March 19 | April 3 | April 18 | October 23 | November 4 | November 19 |
| 28°F — hard freeze | March 4 | March 22 | April 5 | November 2 | November 15 | December 3 |
Measured at Richmond Intl Ap, VA (USW00013740), 8.7 mi from the city's census reference point, elev. 164 ft. NOAA/NCEI 1991–2020 normals. Read each date column as odds over the 30-year record — e.g. "9 in 10 years past by" means only one spring in ten saw a later freeze than that date.
Frost-free windows (computed)
| Window (32°F ends) | Opens | Closes | Length |
|---|---|---|---|
| Cautious (1-in-10 freeze risk at each end) | April 18 | October 23 | 188 days |
| Typical (median freeze dates) | April 3 | November 4 | 215 days |
| Gambler's (9-in-10 freeze risk at each end) | March 19 | November 19 | 245 days |
Pure arithmetic on the freeze-date percentiles above — the "cautious" window opens on the date only 1 year in 10 still sees a later spring freeze, and closes on the date by which only 1 year in 10 has already frozen.
