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
101 years with a frost
Across 101 years with a frost, the median last spring frost at Tartu falls on 10 May and the median first autumn frost on 1 October, which leaves a median of 145 days between them.
In 1967 to 1996 the median growing season was 143 days. That is 2 days fewer than in 1894 to 1923.
Fitted over all years, the growing season changes by -1.5 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
130 years, 1866 to 1996
A day with at least 29.8 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 82.1 mm (3.2 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, 130 years of values from 1866 to 1996.
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: 82.4 mm (3.2 in) in 1869; 75.2 mm (3.0 in) in 1879; 72.9 mm (2.9 in) in 1980.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Tartu, at 1975. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1975 ran 0.2 C (0.4 F) higher 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.
