The annual mean temperature here has risen by 0.2 C (0.1 to 0.2) per decade over 1925 to 2025. In Fahrenheit: 0.3 F (0.2 to 0.4) per decade. The slope is a straight line fitted to 83 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1925 to 2025 | 83 | Rise |
| Mean daily maximum | -0.02 C (-0.09 to 0.04) per decade | -0.04 F (-0.16 to 0.08) per decade | 1925 to 2025 | 83 | Not clearly different from zero |
| Mean daily minimum | 0.3 C (0.3 to 0.4) per decade | 0.6 F (0.5 to 0.7) per decade | 1925 to 2025 | 83 | 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.
Rainfall Return Levels
96 years, 1921 to 2025A day with at least 38.2 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 113.4 mm (4.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 38.2 mm (1.5 in) | |
| 5 years | 57.5 mm (2.3 in) | |
| 10 years | 70.7 mm (2.8 in) | |
| 25 years | 87.6 mm (3.4 in) | |
| 50 years | 100.4 mm (4.0 in) | |
| 100 years | 113.4 mm (4.5 in) | Longer than the 96 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, 96 years of values from 1921 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: 152.4 mm (6.0 in) in 1997; 97.0 mm (3.8 in) in 1969; 90.9 mm (3.6 in) in 2017.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Newport Beach Harbor, at 1954. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1954 ran 0.5 C (1.0 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1954 | -0.5 | -1.0 | 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
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Newport Beach Harbor had a mean temperature of 17.2 C (63.0 F) and 200.6 mm (7.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are N Is NAS (United States, 119 km away), Ensenada (Mexico, 227 km away) and San Diego Intl AP (United States, 117 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| N Is NAS | United States | 119 km (74 mi) | 17.3 C (63.1 F) | 224.3 mm (8.8 in) | 0.37 |
| Ensenada | Mexico | 227 km (141 mi) | 17.2 C (63.0 F) | 286.9 mm (11.3 in) | 0.54 |
| San Diego Intl AP | United States | 117 km (73 mi) | 17.9 C (64.2 F) | 252.0 mm (9.9 in) | 0.82 |
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.
