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

105 years, 1907 to 2014

A day with at least 70.4 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 295.7 mm (11.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Roebourne: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	70.4 mm (2.8 in)
5 years	118.3 mm (4.7 in)
10 years	154.5 mm (6.1 in)
25 years	206.0 mm (8.1 in)
50 years	248.8 mm (9.8 in)
100 years	295.7 mm (11.6 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 105 years of values from 1907 to 2014.

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: 233.7 mm (9.2 in) in 1945; 223.6 mm (8.8 in) in 2013; 221.7 mm (8.7 in) in 1912.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Roebourne, at 1971 and 2007. Each is measured against neighbouring stations.

Relative to 4 neighbouring stations, the station's annual mean temperature from 1971 ran 0.2 C (0.4 F) higher than in the years before (likely change).
Relative to 4 neighbouring stations, the station's annual mean temperature from 2007 ran 0.4 C (0.7 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Roebourne, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1971	+0.2	+0.4	likely	4
2007	-0.4	-0.7	likely	4

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.
