Climate Chart of Hammerfest , Norway

Climate overview

Temperature

January has the lowest monthly mean temperature, -5.6 °C, while the highest monthly mean is 12.4 °C in July. These are averages for each month, not daytime maximum temperatures, so they describe the broad temperature pattern rather than the range visitors may experience within a day. Across the calendar months, the unweighted mean of monthly mean temperatures is 2.5 °C. This summarizes the monthly averages without weighting them by the number of days in each month.

Sunshine

Mean daily sunshine reaches its highest value in July, at 12.04 hours/day, and its lowest in December, at 0.00 hours/day. The figures describe average sunshine duration, not day length, and can give a broad indication of how much sunshine to expect on average rather than a forecast for a particular day. The unweighted mean of the monthly mean daily sunshine durations is 5.74 hours/day. It summarizes the monthly figures and does not represent the same number of sunshine hours on every day.

Rain

Mean daily rainfall is lowest in March, at 0.29 mm/day, and highest in August, at 2.93 mm/day. These daily averages can help frame expectations for different points in the year, but they do not indicate how often rain falls or guarantee dry or wet days. The unweighted mean of the monthly mean daily rainfall figures is 1.45 mm/day. This is a summary of monthly daily averages, not a monthly rainfall total.

Snow

Mean daily snowfall is highest in March, at 21.24 mm/day. This is a daily average, not a monthly total; by itself, it does not show how many days have snowfall, snow depth or snow cover, and it cannot establish skiing conditions. The unweighted mean of the monthly mean daily snowfall figures is 9.45 mm/day. It summarizes monthly averages and should not be read as a measure of snow on the ground.
