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
54 years with a frostAcross 54 years with a frost, the median last spring frost at Mt Morris 2W falls on 7 May and the median first autumn frost on 10 October, which leaves a median of 159 days between them.
Fitted over all years, the growing season changes by +3.9 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1973 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 7 May | n/a | 4 May | n/a | -1.5 days per decade |
| First autumn frost | 10 October | n/a | 13 October | n/a | +2.5 days per decade |
| Growing days | 159 days | n/a | 162 days | n/a | +3.9 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
65 years, 1894 to 2024A day with at least 44.0 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 107.3 mm (4.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 44.0 mm (1.7 in) | |
| 5 years | 59.2 mm (2.3 in) | |
| 10 years | 69.9 mm (2.8 in) | |
| 25 years | 84.3 mm (3.3 in) | |
| 50 years | 95.6 mm (3.8 in) | |
| 100 years | 107.3 mm (4.2 in) | Longer than the 65 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, 65 years of values from 1894 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: 108.0 mm (4.3 in) in 1959; 86.4 mm (3.4 in) in 2010; 80.0 mm (3.1 in) in 1955.

Climate Twins
1996 to 2025 against 1961 to 1990Over 1996 to 2025, Mt Morris 2W had a mean temperature of 9.1 C (48.4 F) and 821.1 mm (32.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Grand Haven Fire Dept (United States, 678 km away), Grimsby (Canada, 145 km away) and Toronto (Canada, 160 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Grand Haven Fire Dept | United States | 678 km (421 mi) | 9.2 C (48.5 F) | 806.7 mm (31.8 in) | 0.54 |
| Grimsby | Canada | 145 km (90 mi) | 8.8 C (47.9 F) | 851.9 mm (33.5 in) | 0.65 |
| Toronto | Canada | 160 km (99 mi) | 8.8 C (47.8 F) | 816.9 mm (32.2 in) | 0.65 |
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.
