34 years of record at Abercorn, 1950 to 1983. 1 years have data for under 90 percent of days and are left out of rankings: 1950.
Cooler than the station meanWarmer than the station mean
One stripe for each of 31 complete years at Abercorn, 1951 to 1983. Blue stripes are years cooler than the station's own mean of 5.4 C (41.8 F); red stripes are warmer. The coolest year was 1978, at 4.4 C (40.0 F), and the warmest was 1953, at 7.3 C (45.1 F). The strongest colour marks a difference of 1.9 C (3.4 F).

The fitted trend in annual mean temperature here over 1951 to 1983 is -0.1 C (-0.3 to 0.2) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: -0.1 F (-0.5 to 0.4) per decade. The slope is a straight line fitted to 31 complete years; the brackets give its 95 percent interval.

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
31 years with a frost
Across 31 years with a frost, the median last spring frost at Abercorn falls on 29 May and the median first autumn frost on 16 September, which leaves a median of 110 days between them.
Fitted over all years, the growing season changes by +0.8 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
33 years, 1951 to 1983
A day with at least 48.8 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 86.2 mm (3.4 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 33 years of values from 1951 to 1983.
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: 87.4 mm (3.4 in) in 1976; 69.6 mm (2.7 in) in 1975; 64.8 mm (2.6 in) in 1952.
