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
21 years with a frostAcross 21 years with a frost, the median last spring frost at Moffett Fed Airfield falls on 25 January and the median first autumn frost on 12 December, which leaves a median of 323 days between them.
| Measure | Median, all years | Earliest period | Recent period (1946 to 2017) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 25 January | n/a | 25 January | n/a | n/a |
| First autumn frost | 12 December | n/a | 12 December | n/a | n/a |
| Growing days | 323 days | n/a | 323 days | n/a | n/a |
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
68 years, 1946 to 2018A day with at least 32.7 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 88.7 mm (3.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 32.7 mm (1.3 in) | |
| 5 years | 45.8 mm (1.8 in) | |
| 10 years | 55.2 mm (2.2 in) | |
| 25 years | 67.9 mm (2.7 in) | |
| 50 years | 78.0 mm (3.1 in) | |
| 100 years | 88.7 mm (3.5 in) | Longer than the 68 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, 68 years of values from 1946 to 2018.
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: 85.3 mm (3.4 in) in 2014; 70.6 mm (2.8 in) in 1970; 68.6 mm (2.7 in) in 1982.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Moffett Fed Airfield, at 1968 and 1999. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1968 ran 0.7 C (1.2 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.4 C (0.7 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1968 | +0.7 | +1.2 | likely | 5 |
| 1999 | -0.4 | -0.7 | likely | 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.
Climate Twins
2003 to 2025 against 1961 to 1990Over 2003 to 2025, Moffett Fed Airfield had a mean temperature of 15.7 C (60.3 F) and 307.8 mm (12.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are King City (United States, 156 km away), Laguna Beach (United States, 577 km away) and Santa Paula (United States, 433 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| King City | United States | 156 km (97 mi) | 15.0 C (59.0 F) | 286.1 mm (11.3 in) | 0.89 |
| Laguna Beach | United States | 577 km (359 mi) | 15.8 C (60.4 F) | 300.4 mm (11.8 in) | 0.94 |
| Santa Paula | United States | 433 km (269 mi) | 16.2 C (61.2 F) | 398.5 mm (15.7 in) | 0.97 |
Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
