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
49 years, 1949 to 1998
A day with at least 74.6 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 262.7 mm (10.3 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 49 years of values from 1949 to 1998.
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: 267.0 mm (10.5 in) in 1958; 198.4 mm (7.8 in) in 1978; 188.5 mm (7.4 in) in 1996.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Barbers Point NAS, at 1985. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1985 ran 0.5 C (0.8 F) higher than in the years before (likely change).

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.
