The fitted trend in annual mean temperature here over 1910 to 2020 is -0.03 C (-0.09 to 0.02) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: -0.06 F (-0.16 to 0.03) per decade. The slope is a straight line fitted to 85 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | -0.03 C (-0.09 to 0.02) per decade | -0.06 F (-0.16 to 0.03) per decade | 1910 to 2020 | 85 | Not clearly different from zero |
| Mean daily maximum | -0.01 C (-0.08 to 0.06) per decade | -0.03 F (-0.15 to 0.10) per decade | 1910 to 2020 | 85 | Not clearly different from zero |
| Mean daily minimum | -0.05 C (-0.10 to 0.00) per decade | -0.10 F (-0.19 to -0.01) per decade | 1910 to 2020 | 85 | Fall |
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
85 years with a frostAcross 85 years with a frost, the median last spring frost at Pilot Rock 1 SE falls on 7 May and the median first autumn frost on 5 October, which leaves a median of 149 days between them.
In 1986 to 2020 the median growing season was 151 days. That is 4 days fewer than in 1910 to 1954.
Fitted over all years, the growing season changes by -0.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1910 to 1954) | Recent period (1986 to 2020) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 7 May | 2 May | 8 May | 6 days later | +0.5 days per decade |
| First autumn frost | 5 October | 15 October | 6 October | 9 days earlier | +0.1 days per decade |
| Growing days | 149 days | 155 days | 151 days | 4 days fewer | -0.4 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
94 years, 1909 to 2020A day with at least 21.9 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 40.3 mm (1.6 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 21.9 mm (0.9 in) | |
| 5 years | 27.5 mm (1.1 in) | |
| 10 years | 30.9 mm (1.2 in) | |
| 25 years | 34.9 mm (1.4 in) | |
| 50 years | 37.7 mm (1.5 in) | |
| 100 years | 40.3 mm (1.6 in) | Longer than the 94 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, 94 years of values from 1909 to 2020.
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: 42.2 mm (1.7 in) in 1996; 37.8 mm (1.5 in) in 1921; 37.1 mm (1.5 in) in 1983.

Climate Twins
2002 to 2020 against 1961 to 1990Over 2002 to 2020, Pilot Rock 1 SE had a mean temperature of 11.0 C (51.8 F) and 372.6 mm (14.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Pomeroy (United States, 146 km away), Walnut Creek (United States, 1,278 km away) and Dayton 1 WSW (United States, 113 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Pomeroy | United States | 146 km (91 mi) | 10.7 C (51.2 F) | 400.7 mm (15.8 in) | 0.65 |
| Walnut Creek | United States | 1,278 km (794 mi) | 11.2 C (52.1 F) | 398.8 mm (15.7 in) | 0.67 |
| Dayton 1 WSW | United States | 113 km (70 mi) | 10.6 C (51.0 F) | 471.5 mm (18.6 in) | 0.73 |
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.
