The fitted trend in annual mean temperature here over 1894 to 2010 is 0.04 C (-0.01 to 0.09) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.07 F (-0.02 to 0.16) per decade. The slope is a straight line fitted to 104 complete years; the brackets give its 95 percent interval.

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

104 years with a frost

Across 104 years with a frost, the median last spring frost at Delphi 2 N falls on 29 April and the median first autumn frost on 9 October, which leaves a median of 163 days between them.

In 1976 to 2010 the median growing season was 166 days. That is 6 days more than in 1894 to 1928.

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

Frost dates and growing season at Delphi 2 N
Measure	Median, all years	Earliest period (1894 to 1928)	Recent period (1976 to 2010)	Recent against earliest	Fitted trend
Last spring frost	29 April	2 May	27 April	5 days earlier	-0.6 days per decade
First autumn frost	9 October	9 October	11 October	2 days later	+0.3 days per decade
Growing days	163 days	160 days	166 days	6 days more	+1.0 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

109 years, 1895 to 2010

A day with at least 59.3 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 137.0 mm (5.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Delphi 2 N: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	59.3 mm (2.3 in)
5 years	78.8 mm (3.1 in)
10 years	92.3 mm (3.6 in)
25 years	109.8 mm (4.3 in)
50 years	123.2 mm (4.9 in)
100 years	137.0 mm (5.4 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 109 years of values from 1895 to 2010.

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: 176.8 mm (7.0 in) in 1968; 121.4 mm (4.8 in) in 1989; 115.3 mm (4.5 in) in 1942.
