Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.
Frost Dates and Growing Season
77 years with a frostAcross 77 years with a frost, the median last spring frost at Calico Rock 2 WSW falls on 13 April and the median first autumn frost on 22 October, which leaves a median of 191 days between them.
In 1995 to 2025 the median growing season was 193 days. That is 2 days fewer than in 1916 to 1974.
Fitted over all years, the growing season changes by -0.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1916 to 1974) | Recent period (1995 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 13 April | 10 April | 16 April | 6 days later | +0.5 days per decade |
| First autumn frost | 22 October | 23 October | 26 October | 3 days later | +0.1 days per decade |
| Growing days | 191 days | 195 days | 193 days | 2 days fewer | -0.5 days per decade |
A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.
Rainfall Return Levels
119 years, 1905 to 2025A day with at least 76.3 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 189.9 mm (7.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 76.3 mm (3.0 in) | |
| 5 years | 101.8 mm (4.0 in) | |
| 10 years | 120.5 mm (4.7 in) | |
| 25 years | 146.4 mm (5.8 in) | |
| 50 years | 167.4 mm (6.6 in) | |
| 100 years | 189.9 mm (7.5 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 119 years of values from 1905 to 2025.
A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.
The largest wettest-day totals in the fit: 203.2 mm (8.0 in) in 1913; 194.8 mm (7.7 in) in 1949; 177.8 mm (7.0 in) in 2008.

Climate Twins
2010 to 2025 against 1961 to 1990Over 2010 to 2025, Calico Rock 2 WSW had a mean temperature of 14.4 C (57.8 F) and 1,274.0 mm (50.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Carthage (United States, 558 km away), Lenoir City (United States, 712 km away) and Murfreesboro 5 N (United States, 521 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Carthage | United States | 558 km (347 mi) | 14.3 C (57.8 F) | 1,303.0 mm (51.3 in) | 0.35 |
| Lenoir City | United States | 712 km (442 mi) | 14.1 C (57.4 F) | 1,329.6 mm (52.3 in) | 0.51 |
| Murfreesboro 5 N | United States | 521 km (324 mi) | 14.5 C (58.1 F) | 1,348.4 mm (53.1 in) | 0.53 |
Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
