The annual mean temperature here has risen by 0.2 C (0.1 to 0.2) per decade over 1897 to 1991. In Fahrenheit: 0.3 F (0.2 to 0.3) 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 | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.3) per decade | 1897 to 1991 | 95 | Rise |
| Mean daily maximum | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1897 to 1991 | 95 | Rise |
| Mean daily minimum | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1897 to 1991 | 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.
Rainfall Return Levels
112 years, 1880 to 1991A day with at least 49.1 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 97.3 mm (3.8 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 49.1 mm (1.9 in) | |
| 5 years | 61.5 mm (2.4 in) | |
| 10 years | 69.9 mm (2.8 in) | |
| 25 years | 80.8 mm (3.2 in) | |
| 50 years | 89.0 mm (3.5 in) | |
| 100 years | 97.3 mm (3.8 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 112 years of values from 1880 to 1991.
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: 99.1 mm (3.9 in) in 1920; 95.0 mm (3.7 in) in 1987; 87.1 mm (3.4 in) in 1955.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Perth Regional Office, at 1969 and 1987. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1969 ran 0.3 C (0.6 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1987 ran 0.1 C (0.3 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1969 | +0.3 | +0.6 | likely | 5 |
| 1987 | +0.1 | +0.3 | possible | 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.
