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
61 years with a frost
Across 61 years with a frost, the median last spring frost at Alpine falls on 5 April and the median first autumn frost on 6 November, which leaves a median of 214 days between them.
In 1972 to 2018 the median growing season was 210 days. That is 10 days fewer than in 1930 to 1970.
Fitted over all years, the growing season changes by -1.2 days per decade at this station.

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
82 years, 1912 to 2018
A day with at least 43.7 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 83.8 mm (3.3 in) of rain is expected about once in 100 years.

Longer than the 82 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, 82 years of values from 1912 to 2018.
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: 79.5 mm (3.1 in) in 1968; 73.7 mm (2.9 in) in 1944; 72.1 mm (2.8 in) in 1989.
Station Changes
2 suspected
2 changes were suspected in the annual mean temperature of Alpine, at 1959 and 1970. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1959 ran 0.9 C (1.6 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1970 ran 0.5 C (1.0 F) higher than in the years before (possible change).

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.
