The fitted trend in annual mean temperature here over 1895 to 2004 is 0.04 C (-0.01 to 0.10) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.08 F (-0.01 to 0.17) per decade. The slope is a straight line fitted to 95 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.04 C (-0.01 to 0.10) per decade | 0.08 F (-0.01 to 0.17) per decade | 1895 to 2004 | 95 | Not clearly different from zero |
| Mean daily maximum | 0.00 C (-0.06 to 0.05) per decade | 0.00 F (-0.10 to 0.10) per decade | 1895 to 2004 | 95 | Not clearly different from zero |
| Mean daily minimum | 0.09 C (0.04 to 0.14) per decade | 0.2 F (0.1 to 0.3) per decade | 1895 to 2004 | 95 | Rise |
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
95 years with a frostAcross 95 years with a frost, the median last spring frost at Valparaiso Wtr Wks falls on 28 April and the median first autumn frost on 13 October, which leaves a median of 168 days between them.
In 1972 to 2004 the median growing season was 171 days. That is 3 days more than in 1895 to 1935.
Fitted over all years, the growing season changes by +0.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1895 to 1935) | Recent period (1972 to 2004) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 28 April | 29 April | 27 April | 2 days earlier | -0.2 days per decade |
| First autumn frost | 13 October | 13 October | 15 October | 2 days later | +0.2 days per decade |
| Growing days | 168 days | 168 days | 171 days | 3 days more | +0.4 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.
Rainfall Return Levels
99 years, 1894 to 2004A day with at least 56.0 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 182.2 mm (7.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 56.0 mm (2.2 in) | |
| 5 years | 76.9 mm (3.0 in) | |
| 10 years | 94.8 mm (3.7 in) | |
| 25 years | 123.4 mm (4.9 in) | |
| 50 years | 150.1 mm (5.9 in) | |
| 100 years | 182.2 mm (7.2 in) | Longer than the 99 years of record |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 99 years of values from 1894 to 2004.
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: 186.4 mm (7.3 in) in 1923; 186.4 mm (7.3 in) in 1983; 140.5 mm (5.5 in) in 1996.
