A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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
75 years with a frostAcross 75 years with a frost, the median last spring frost at Hereford falls on 18 April and the median first autumn frost on 23 October, which leaves a median of 186 days between them.
In 1990 to 2024 the median growing season was 187 days. That is 4 days more than in 1909 to 1972.
Fitted over all years, the growing season changes by +1.0 days per decade at this station.
| Measure | Median, all years | Earliest period (1909 to 1972) | Recent period (1990 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 18 April | 22 April | 16 April | 6 days earlier | -0.9 days per decade |
| First autumn frost | 23 October | 25 October | 23 October | 2 days earlier | +0.1 days per decade |
| Growing days | 186 days | 183 days | 187 days | 4 days more | +1.0 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
86 years, 1908 to 2024A day with at least 53.1 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 126.6 mm (5.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 53.1 mm (2.1 in) | |
| 5 years | 72.8 mm (2.9 in) | |
| 10 years | 85.9 mm (3.4 in) | |
| 25 years | 102.3 mm (4.0 in) | |
| 50 years | 114.5 mm (4.5 in) | |
| 100 years | 126.6 mm (5.0 in) | Longer than the 86 years of record |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 86 years of values from 1908 to 2024.
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: 134.6 mm (5.3 in) in 1950; 126.7 mm (5.0 in) in 2008; 119.4 mm (4.7 in) in 1998.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Hereford, at 1972 and 2011. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1972 ran 0.3 C (0.5 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2011 ran 0.2 C (0.3 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1972 | +0.3 | +0.5 | likely | 5 |
| 2011 | -0.2 | -0.3 | likely | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
Climate Twins
2006 to 2024 against 1961 to 1990Over 2006 to 2024, Hereford had a mean temperature of 14.3 C (57.8 F) and 467.9 mm (18.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Gruver (United States, 184 km away), Spearman (United States, 189 km away) and Panhandle (United States, 109 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Gruver | United States | 184 km (114 mi) | 14.2 C (57.6 F) | 466.3 mm (18.4 in) | 0.59 |
| Spearman | United States | 189 km (117 mi) | 14.5 C (58.0 F) | 488.5 mm (19.2 in) | 0.60 |
| Panhandle | United States | 109 km (68 mi) | 14.3 C (57.8 F) | 528.3 mm (20.8 in) | 0.67 |
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.
