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
62 years with a frostAcross 62 years with a frost, the median last spring frost at Titusville Wtr Wks falls on 21 May and the median first autumn frost on 3 October, which leaves a median of 131 days between them.
In 1994 to 2025 the median growing season was 145 days. That is 23 days more than in 1955 to 1991.
Fitted over all years, the growing season changes by +6.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1955 to 1991) | Recent period (1994 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 May | 26 May | 18 May | 8 days earlier | -2.0 days per decade |
| First autumn frost | 3 October | 26 September | 10 October | 14 days later | +4.3 days per decade |
| Growing days | 131 days | 122 days | 145 days | 23 days more | +6.3 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
68 years, 1955 to 2025A day with at least 51.3 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 101.1 mm (4.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 51.3 mm (2.0 in) | |
| 5 years | 64.7 mm (2.5 in) | |
| 10 years | 73.6 mm (2.9 in) | |
| 25 years | 84.7 mm (3.3 in) | |
| 50 years | 92.9 mm (3.7 in) | |
| 100 years | 101.1 mm (4.0 in) | Longer than the 68 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, 68 years of values from 1955 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: 98.8 mm (3.9 in) in 2019; 94.0 mm (3.7 in) in 1990; 83.3 mm (3.3 in) in 2014.
Station Changes

- Relative to 5 neighbouring stations, the station's annual mean temperature from 1961 ran 0.4 C (0.8 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1961 | -0.4 | -0.8 | 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
2010 to 2025 against 1961 to 1990Over 2010 to 2025, Titusville Wtr Wks had a mean temperature of 8.6 C (47.4 F) and 1,201.6 mm (47.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Marion Ctr 2 SE (United States, 112 km away), Chardon (United States, 125 km away) and Shepaug Dam (United States, 531 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Marion Ctr 2 SE | United States | 112 km (70 mi) | 8.7 C (47.6 F) | 1,231.6 mm (48.5 in) | 0.59 |
| Shepaug Dam | United States | 531 km (330 mi) | 8.7 C (47.6 F) | 1,252.4 mm (49.3 in) | 0.62 |
| Chardon | United States | 125 km (78 mi) | 8.5 C (47.2 F) | 1,161.1 mm (45.7 in) | 0.62 |
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.
