Rebriha Weather Records (RSM00029923)

The annual mean temperature here has risen by 0.17 C (0.01 to 0.33) per decade over 1955 to 2018. In Fahrenheit: 0.30 F (0.02 to 0.59) per decade. The slope is a straight line fitted to 58 complete years; the brackets give its 95 percent interval.

Across 58 years with a frost, the median last spring frost at Rebriha falls on 24 May and the median first autumn frost on 15 September, which leaves a median of 114 days between them.

Fitted over all years, the growing season changes by +1.0 days per decade at this station.

A day with at least 26.9 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 59.6 mm (2.3 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, 62 years of values from 1955 to 2019.

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: 64.0 mm (2.5 in) in 1983; 49.2 mm (1.9 in) in 2005; 48.0 mm (1.9 in) in 1958.
