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

35 years with a frost

Across 35 years with a frost, the median last spring frost at Anchialos falls on 11 March and the median first autumn frost on 10 December, which leaves a median of 276 days between them.

Fitted over all years, the growing season changes by +4.2 days per decade at this station.

Frost dates and growing season at Anchialos
Measure	Median, all years	Earliest period	Recent period (1967 to 2004)	Recent against earliest	Fitted trend
Last spring frost	11 March	n/a	13 March	n/a	-3.2 days per decade
First autumn frost	10 December	n/a	10 December	n/a	+1.0 days per decade
Growing days	276 days	n/a	277 days	n/a	+4.2 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.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Anchialos, at 1965. Each is measured against neighbouring stations.

Relative to 4 neighbouring stations, the station's annual mean temperature from 1965 ran 0.4 C (0.7 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Anchialos, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1965	+0.4	+0.7	likely	4

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.
