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
53 years with a frost
Across 53 years with a frost, the median last spring frost at Ladysmith 3W falls on 19 May and the median first autumn frost on 24 September, which leaves a median of 120 days between them.
Fitted over all years, the growing season changes by +0.8 days per decade at this station.

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
70 years, 1902 to 2025
A day with at least 58.9 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 127.9 mm (5.0 in) of rain is expected about once in 100 years.

Longer than the 70 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, 70 years of values from 1902 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: 129.0 mm (5.1 in) in 1960; 114.3 mm (4.5 in) in 2018; 110.7 mm (4.4 in) in 1941.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Ladysmith 3W, at 1978. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 0.2 C (0.4 F) lower than in the years before (possible change).

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 1990
Over 2011 to 2025, Ladysmith 3W had a mean temperature of 5.2 C (41.3 F) and 911.8 mm (35.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Bethlehem (United States, 1,534 km away), Berlin (United States, 1,569 km away) and Bancroft (Canada, 1,039 km away).
Climate twins of Ladysmith 3W: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
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.
