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

96 years with a frost

Across 96 years with a frost, the median last spring frost at Westcliffe falls on 11 June and the median first autumn frost on 10 September, which leaves a median of 88 days between them.

In 1993 to 2025 the median growing season was 95 days. That is 6 days more than in 1896 to 1951.

Fitted over all years, the growing season changes by +0.6 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

112 years, 1896 to 2025

A day with at least 30.8 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 108.6 mm (4.3 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 112 years of values from 1896 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: 96.8 mm (3.8 in) in 1955; 93.0 mm (3.7 in) in 1966; 88.6 mm (3.5 in) in 1936.

Climate Twins

2010 to 2025 against 1961 to 1990

Over 2010 to 2025, Westcliffe had a mean temperature of 6.9 C (44.3 F) and 308.7 mm (12.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Panguitch (United States, 611 km away), Norwood (United States, 247 km away) and Koosharem (United States, 561 km away).

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.
