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
52 years with a frostAcross 52 years with a frost, the median last spring frost at Lebanon Muni AP falls on 14 May and the median first autumn frost on 6 October, which leaves a median of 145 days between them.
Fitted over all years, the growing season changes by +4.3 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1986 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 14 May | n/a | 13 May | n/a | -1.8 days per decade |
| First autumn frost | 6 October | n/a | 8 October | n/a | +2.5 days per decade |
| Growing days | 145 days | n/a | 148 days | n/a | +4.3 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
53 years, 1963 to 2025A day with at least 52.1 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 128.0 mm (5.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 52.1 mm (2.1 in) | |
| 5 years | 69.3 mm (2.7 in) | |
| 10 years | 81.9 mm (3.2 in) | |
| 25 years | 99.1 mm (3.9 in) | |
| 50 years | 113.1 mm (4.5 in) | |
| 100 years | 128.0 mm (5.0 in) | Longer than the 53 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, 53 years of values from 1963 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: 119.4 mm (4.7 in) in 1999; 96.5 mm (3.8 in) in 1983; 95.8 mm (3.8 in) in 1969.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Lebanon Muni AP, at 2008. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2008 ran 0.3 C (0.5 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 2008 | +0.3 | +0.5 | possible | 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, Lebanon Muni AP had a mean temperature of 8.5 C (47.4 F) and 957.1 mm (37.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Grand Rapids (United States, 1,074 km away), Allegan 5NE (United States, 1,100 km away) and Angola (United States, 1,061 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Grand Rapids | United States | 1,074 km (667 mi) | 8.6 C (47.4 F) | 941.7 mm (37.1 in) | 0.46 |
| Allegan 5NE | United States | 1,100 km (684 mi) | 8.6 C (47.5 F) | 971.0 mm (38.2 in) | 0.56 |
| Angola | United States | 1,061 km (659 mi) | 8.5 C (47.3 F) | 905.2 mm (35.6 in) | 0.60 |
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.
