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

69 years with a frost

Across 69 years with a frost, the median last spring frost at Two Rivers falls on 28 April and the median first autumn frost on 16 October, which leaves a median of 167 days between them.

In 1995 to 2025 the median growing season was 174 days. That is 11 days more than in 1952 to 1985.

Fitted over all years, the growing season changes by +3.2 days per decade at this station.

Frost dates and growing season at Two Rivers
Measure	Median, all years	Earliest period (1952 to 1985)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	28 April	5 May	26 April	9 days earlier	-1.5 days per decade
First autumn frost	16 October	14 October	21 October	7 days later	+1.7 days per decade
Growing days	167 days	163 days	174 days	11 days more	+3.2 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

73 years, 1952 to 2025

A day with at least 48.3 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 156.9 mm (6.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Two Rivers: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	48.3 mm (1.9 in)
5 years	67.1 mm (2.6 in)
10 years	82.9 mm (3.3 in)
25 years	107.6 mm (4.2 in)
50 years	130.2 mm (5.1 in)
100 years	156.9 mm (6.2 in)	Longer than the 73 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, 73 years of values from 1952 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: 119.9 mm (4.7 in) in 1986; 119.4 mm (4.7 in) in 2021; 118.1 mm (4.6 in) in 1952.

Station Changes

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Two Rivers had a mean temperature of 7.3 C (45.1 F) and 863.3 mm (34.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Harbor Beach 1 SSE (United States, 395 km away), Port Hope (Canada, 742 km away) and Frankfort 2NE (United States, 122 km away).

Climate twins of Two Rivers: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Harbor Beach 1 SSE	United States	395 km (245 mi)	7.5 C (45.4 F)	884.4 mm (34.8 in)	0.61
Port Hope	Canada	742 km (461 mi)	7.1 C (44.8 F)	776.4 mm (30.6 in)	0.70
Frankfort 2NE	United States	122 km (76 mi)	7.3 C (45.1 F)	857.3 mm (33.8 in)	0.78

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.
