Complete yearUnder 90 percent of days
61 years of record at Oracle 2 SE, 1950 to 2011. 7 years have data for under 90 percent of days and are left out of rankings: 1950, 1957, 1965, 2005, 2008, 2009, 2011.
Cooler than the station meanWarmer than the station mean
One stripe for each of 48 complete years at Oracle 2 SE, 1951 to 2007. Blue stripes are years cooler than the station's own mean of 16.7 C (62.1 F); red stripes are warmer. The coolest year was 1955, at 15.4 C (59.7 F), and the warmest was 1959, at 17.8 C (64.1 F). The strongest colour marks a difference of 1.4 C (2.5 F).

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
48 years with a frost
Across 48 years with a frost, the median last spring frost at Oracle 2 SE falls on 3 April and the median first autumn frost on 13 November, which leaves a median of 226 days between them.
Fitted over all years, the growing season changes by -0.2 days per decade at this station.

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
55 years, 1951 to 2007
A day with at least 47.7 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 81.0 mm (3.2 in) of rain is expected about once in 100 years.

Longer than the 55 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, 55 years of values from 1951 to 2007.
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: 82.0 mm (3.2 in) in 1954; 80.8 mm (3.2 in) in 1979; 77.0 mm (3.0 in) in 1994.
