The fitted trend in annual mean temperature here over 1929 to 2009 is 0.00 C (-0.06 to 0.07) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.0 F (-0.1 to 0.1) per decade. The slope is a straight line fitted to 80 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.00 C (-0.06 to 0.07) per decade | 0.0 F (-0.1 to 0.1) per decade | 1929 to 2009 | 80 | Not clearly different from zero |
| Mean daily maximum | 0.08 C (0.02 to 0.14) per decade | 0.14 F (0.03 to 0.26) per decade | 1929 to 2009 | 80 | Rise |
| Mean daily minimum | -0.08 C (-0.17 to 0.01) per decade | -0.14 F (-0.30 to 0.01) per decade | 1929 to 2009 | 80 | Not clearly different from zero |
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
80 years with a frostAcross 80 years with a frost, the median last spring frost at Isparta falls on 6 April and the median first autumn frost on 8 November, which leaves a median of 212 days between them.
In 1979 to 2009 the median growing season was 202 days. That is 13 days fewer than in 1929 to 1958.
Fitted over all years, the growing season changes by -2.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1929 to 1958) | Recent period (1979 to 2009) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 6 April | 9 April | 13 April | 4 days later | +0.3 days per decade |
| First autumn frost | 8 November | 15 November | 1 November | 14 days earlier | -2.2 days per decade |
| Growing days | 212 days | 215 days | 202 days | 13 days fewer | -2.4 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.
