The annual mean temperature here has risen by 0.3 C (0.3 to 0.4) per decade over 1909 to 2025. In Fahrenheit: 0.6 F (0.5 to 0.7) per decade. The slope is a straight line fitted to 112 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.3 C (0.3 to 0.4) per decade | 0.6 F (0.5 to 0.7) per decade | 1909 to 2025 | 112 | Rise |
| Mean daily maximum | 0.2 C (0.2 to 0.3) per decade | 0.4 F (0.3 to 0.5) per decade | 1909 to 2025 | 112 | Rise |
| Mean daily minimum | 0.4 C (0.4 to 0.5) per decade | 0.8 F (0.7 to 0.8) per decade | 1909 to 2025 | 112 | Rise |
A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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
23 years with a frostAcross 23 years with a frost, the median last spring frost at Pasadena falls on 15 February and the median first autumn frost on 11 December, which leaves a median of 296 days between them.
| Measure | Median, all years | Earliest period | Recent period (1909 to 1990) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 February | n/a | 15 February | n/a | n/a |
| First autumn frost | 11 December | n/a | 11 December | n/a | n/a |
| Growing days | 296 days | n/a | 296 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
114 years, 1893 to 2025A day with at least 72.3 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 195.2 mm (7.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 72.3 mm (2.8 in) | |
| 5 years | 106.2 mm (4.2 in) | |
| 10 years | 128.3 mm (5.1 in) | |
| 25 years | 155.6 mm (6.1 in) | |
| 50 years | 175.6 mm (6.9 in) | |
| 100 years | 195.2 mm (7.7 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 114 years of values from 1893 to 2025.
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: 195.6 mm (7.7 in) in 1938; 179.8 mm (7.1 in) in 1943; 165.4 mm (6.5 in) in 1956.
Station Changes
3 suspected3 changes were suspected in the annual mean temperature of Pasadena, at 1970, 1982 and 2000. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1970 ran 0.2 C (0.4 F) higher than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1982 ran 0.4 C (0.7 F) lower than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2000 ran 0.8 C (1.4 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1970 | +0.2 | +0.4 | possible | 5 |
| 1982 | -0.4 | -0.7 | possible | 5 |
| 2000 | +0.8 | +1.4 | 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
2010 to 2025 against 1961 to 1990Over 2010 to 2025, Pasadena had a mean temperature of 19.8 C (67.6 F) and 490.8 mm (19.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Tel Aviv Reading (Israel, 12,123 km away), Bet Dagan (Israel, 12,134 km away) and Melilla (Spain, 9,774 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Tel Aviv Reading | Israel | 12,123 km (7,533 mi) | 19.8 C (67.7 F) | 511.0 mm (20.1 in) | 0.75 |
| Bet Dagan | Israel | 12,134 km (7,540 mi) | 19.1 C (66.4 F) | 549.5 mm (21.6 in) | 1.14 |
| Melilla | Spain | 9,774 km (6,073 mi) | 18.5 C (65.4 F) | 362.2 mm (14.3 in) | 1.46 |
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.
