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

43 years with a frost

Across 43 years with a frost, the median last spring frost at Gathright Dam falls on 27 April and the median first autumn frost on 20 October, which leaves a median of 172 days between them.

Fitted over all years, the growing season changes by +11.5 days per decade at this station.

First autumn frost20 Octobern/a24 Octobern/a+7.6 days per decade
Growing days172 daysn/a184 daysn/a+11.5 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

45 years, 1981 to 2025

A day with at least 51.4 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 138.7 mm (5.5 in) of rain is expected about once in 100 years.

50 years117.1 mm (4.6 in)Longer than the 45 years of record
100 years138.7 mm (5.5 in)Longer than the 45 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, 45 years of values from 1981 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: 168.4 mm (6.6 in) in 1985; 88.1 mm (3.5 in) in 2016; 83.8 mm (3.3 in) in 2003.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Gathright Dam, at 2010. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2010 ran 0.2 C (0.3 F) lower than in the years before (likely 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.
