34 years of record at Arctic Bay, 1937 to 1976. 7 years have data for under 90 percent of days and are left out of rankings: 1937, 1940, 1948, 1959, 1960, 1966, 1974.
Cooler than the station meanWarmer than the station mean
One stripe for each of 25 complete years at Arctic Bay, 1939 to 1976. Blue stripes are years cooler than the station's own mean of -13.8 C (7.2 F); red stripes are warmer. The coolest year was 1961, at -15.7 C (3.7 F), and the warmest was 1947, at -10.4 C (13.3 F). The strongest colour marks a difference of 3.4 C (6.1 F).

This station does not have enough complete years (30 are needed) to fit a temperature trend.
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
25 years with a frost
Across 25 years with a frost, the median last spring frost at Arctic Bay falls on 29 June and the median first autumn frost on 3 July, which leaves a median of 6 days between them.
Fitted over all years, the growing season changes by +0.3 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
31 years, 1938 to 1976
A day with at least 13.2 mm (0.5 in) of rain is expected about once in 2 years. A day with at least 40.4 mm (1.6 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, 31 years of values from 1938 to 1976.
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: 38.1 mm (1.5 in) in 1938; 26.7 mm (1.1 in) in 1964; 26.2 mm (1.0 in) in 1953.
