The annual mean temperature here has risen by 0.2 C (0.2 to 0.3) per decade over 1933 to 2024. In Fahrenheit: 0.4 F (0.3 to 0.6) per decade. The slope is a straight line fitted to 86 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 (0.2 to 0.3) per decade | 0.4 F (0.3 to 0.6) per decade | 1933 to 2024 | 86 | Rise |
| Mean daily maximum | 0.2 C (0.1 to 0.3) per decade | 0.3 F (0.2 to 0.5) per decade | 1933 to 2024 | 86 | Rise |
| Mean daily minimum | 0.3 C (0.2 to 0.4) per decade | 0.5 F (0.4 to 0.7) per decade | 1933 to 2024 | 86 | 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
86 years with a frostAcross 86 years with a frost, the median last spring frost at Homer AP falls on 22 May and the median first autumn frost on 22 September, which leaves a median of 125 days between them.
In 1995 to 2024 the median growing season was 138 days. That is 34 days more than in 1933 to 1967.
Fitted over all years, the growing season changes by +5.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1933 to 1967) | Recent period (1995 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 22 May | 31 May | 16 May | 15 days earlier | -3.0 days per decade |
| First autumn frost | 22 September | 15 September | 27 September | 12 days later | +2.4 days per decade |
| Growing days | 125 days | 104 days | 138 days | 34 days more | +5.4 days per decade |
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
87 years, 1933 to 2024A day with at least 31.9 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 83.0 mm (3.3 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 31.9 mm (1.3 in) | |
| 5 years | 42.0 mm (1.7 in) | |
| 10 years | 49.9 mm (2.0 in) | |
| 25 years | 61.5 mm (2.4 in) | |
| 50 years | 71.6 mm (2.8 in) | |
| 100 years | 83.0 mm (3.3 in) | Longer than the 87 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, 87 years of values from 1933 to 2024.
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: 88.9 mm (3.5 in) in 1939; 76.7 mm (3.0 in) in 1952; 73.2 mm (2.9 in) in 2002.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2010 to 2024 against 1961 to 1990Over 2010 to 2024, Homer AP had a mean temperature of 4.5 C (40.2 F) and 639.8 mm (25.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Spinkabo (Sweden, 6,924 km away), Lommaryd (Sweden, 6,890 km away) and North Lake (United States, 4,108 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Spinkabo | Sweden | 6,924 km (4,302 mi) | 4.7 C (40.5 F) | 771.3 mm (30.4 in) | 1.24 |
| Lommaryd | Sweden | 6,890 km (4,281 mi) | 4.8 C (40.7 F) | 609.2 mm (24.0 in) | 1.26 |
| North Lake | United States | 4,108 km (2,553 mi) | 5.3 C (41.5 F) | 513.7 mm (20.2 in) | 1.29 |
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.
