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
65 years with a frostAcross 65 years with a frost, the median last spring frost at Steveston falls on 18 April and the median first autumn frost on 16 October, which leaves a median of 178 days between them.
In 1932 to 1969 the median growing season was 178 days. That is 2 days more than in 1897 to 1926.
Fitted over all years, the growing season changes by -0.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1897 to 1926) | Recent period (1932 to 1969) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 18 April | 18 April | 21 April | 3 days later | +1.1 days per decade |
| First autumn frost | 16 October | 12 October | 19 October | 7 days later | +0.8 days per decade |
| Growing days | 178 days | 176 days | 178 days | 2 days more | -0.2 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.

| 100 years | 74.2 mm (2.9 in) | Longer than the 72 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, 72 years of values from 1896 to 1970.
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: 73.2 mm (2.9 in) in 1896; 64.3 mm (2.5 in) in 1909; 64.3 mm (2.5 in) in 1955.
