A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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

44 years with a frost

Across 44 years with a frost, the median last spring frost at Boardman falls on 17 April and the median first autumn frost on 16 October, which leaves a median of 183 days between them.

Fitted over all years, the growing season changes by +2.3 days per decade at this station.

First autumn frost16 Octobern/a19 Octobern/a+3.1 days per decade
Growing days183 daysn/a191 daysn/a+2.3 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

48 years, 1972 to 2025

A day with at least 16.9 mm (0.7 in) of rain is expected about once in 2 years. A day with at least 39.3 mm (1.5 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, 48 years of values from 1972 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: 36.3 mm (1.4 in) in 2006; 31.8 mm (1.3 in) in 1998; 29.5 mm (1.2 in) in 2024.

Station Changes

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

Climate Twins

2007 to 2024 against 1961 to 1990

Over 2007 to 2024, Boardman had a mean temperature of 12.1 C (53.7 F) and 212.0 mm (8.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Fallon Naas (United States, 719 km away), Caliente (United States, 1,010 km away) and Mina (United States, 840 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.
