The annual mean temperature here has risen by 0.06 C (0.01 to 0.11) per decade over 1896 to 2025. In Fahrenheit: 0.11 F (0.01 to 0.20) per decade. The slope is a straight line fitted to 98 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.06 C (0.01 to 0.11) per decade | 0.11 F (0.01 to 0.20) per decade | 1896 to 2025 | 98 | Rise |
| Mean daily maximum | 0.05 C (0.00 to 0.11) per decade | 0.09 F (0.00 to 0.19) per decade | 1896 to 2025 | 98 | Not clearly different from zero |
| Mean daily minimum | 0.07 C (0.01 to 0.12) per decade | 0.12 F (0.01 to 0.22) per decade | 1896 to 2025 | 98 | 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
98 years with a frostAcross 98 years with a frost, the median last spring frost at Waukesha Wwtp falls on 3 May and the median first autumn frost on 11 October, which leaves a median of 163 days between them.
In 1978 to 2025 the median growing season was 166 days. The two periods have the same number of growing days.
Fitted over all years, the growing season changes by +0.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1896 to 1935) | Recent period (1978 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 3 May | 4 May | 27 April | 7 days earlier | -0.5 days per decade |
| First autumn frost | 11 October | 14 October | 13 October | 1 day earlier | +0.1 days per decade |
| Growing days | 163 days | 166 days | 166 days | no change | +0.6 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

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 122 years of values from 1893 to 2025.
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: 152.4 mm (6.0 in) in 2025; 142.5 mm (5.6 in) in 2022; 129.3 mm (5.1 in) in 1952.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Waukesha Wwtp, at 1940. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1940 ran 0.4 C (0.7 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1940 | -0.4 | -0.7 | likely | 5 |
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.
