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
64 years, 1958 to 2025A day with at least 75.5 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 241.0 mm (9.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 75.5 mm (3.0 in) | |
| 5 years | 109.3 mm (4.3 in) | |
| 10 years | 135.4 mm (5.3 in) | |
| 25 years | 173.2 mm (6.8 in) | |
| 50 years | 205.3 mm (8.1 in) | |
| 100 years | 241.0 mm (9.5 in) | Longer than the 64 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, 64 years of values from 1958 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: 215.4 mm (8.5 in) in 2007; 205.7 mm (8.1 in) in 2021; 173.5 mm (6.8 in) in 2025.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Port Mansfield, at 1978 and 1991. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 0.8 C (1.4 F) lower than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1991 ran 0.6 C (1.1 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1978 | -0.8 | -1.4 | possible | 5 |
| 1991 | +0.6 | +1.1 | 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
2006 to 2025 against 1961 to 1990Over 2006 to 2025, Port Mansfield had a mean temperature of 23.2 C (73.7 F) and 679.0 mm (26.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Francisco Gonzalez Villarreal (Mexico, 144 km away), Cerralvo (Dge) (Mexico, 224 km away) and Nuri (Mexico, 1,192 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Francisco Gonzalez Villarreal | Mexico | 144 km (89 mi) | 23.1 C (73.6 F) | 732.4 mm (28.8 in) | 0.59 |
| Cerralvo (Dge) | Mexico | 224 km (139 mi) | 22.8 C (73.1 F) | 674.4 mm (26.6 in) | 0.71 |
| Nuri | Mexico | 1,192 km (741 mi) | 23.2 C (73.8 F) | 667.1 mm (26.3 in) | 0.72 |
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.
