Climate overview

Temperature

Monthly mean temperature is lowest in February at -13.2 °C, then reaches its highest point in July at 8.4 °C. These are monthly averages, not daytime highs or lows, so individual days may differ from the broad conditions they describe. Across the calendar-month means, the unweighted mean is -2.7 °C. This provides an overall summary, but it is not a day-weighted annual average and does not describe the temperature range within any month.

Rain

Mean daily rainfall is lowest in January at 0.04 mm/day, making it the conditional option for visitors who prioritise lower average rainfall. The highest monthly mean is in September at 3.38 mm/day; allow for wet-weather plans then, while remembering that these averages do not show how often rain falls or guarantee dry or wet conditions on a given day. The unweighted mean across the monthly daily-rainfall means is 1.20 mm/day. These figures are daily averages, not monthly rainfall totals.

Snow

Mean daily snowfall is highest in November at 15.16 mm/day, and lowest in July at 0.13 mm/day. These are daily averages, not monthly totals; they do not establish the number of snowy days, snow depth, persistent cover or skiing conditions. The unweighted mean across the monthly daily-snowfall means is 8.33 mm/day. Treat this as a broad statistical summary, not a prediction of snowfall during a particular trip.

Sunshine

Mean daily sunshine reaches its highest level in July at 10.57 hours/day, while its lowest is in December at 1.00 hours/day. The brighter-month figure can help when planning outdoor time, but sunshine duration is not the same as day length and does not promise sunshine on any particular day. The unweighted mean of the monthly sunshine means is 6.14 hours/day per day, an overview rather than a guarantee of the conditions during a specific visit.

Best Travel Time Guide for Nuuk, Greenland: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly averages, February is the relevant reference point, with a monthly mean temperature of -13.2 °C; pack for cold conditions, while allowing for day-to-day variation. By contrast, July has the highest monthly mean at 8.4 °C, which may suit those seeking the mildest monthly average, but does not guarantee warm daytime weather. If lower average rainfall is your priority, consider January, when mean daily rainfall is 0.04 mm/day. For September, the highest-rainfall month at 3.38 mm/day, include waterproof layers and flexible plans; the averages cannot tell you whether rain will fall on a particular day or how frequently.

For daylight outdoor planning, July has the greatest mean daily sunshine duration at 10.57 hours/day, whereas December has the least at 1.00 hours/day. These are sunshine-duration averages, not measures of day length, so they cannot by themselves predict usable daylight or actual weather on your dates. Snowfall averages are highest in November at 15.16 mm/day per day. This can inform cold-weather preparation, but it does not reveal how many days will see snow or whether snow will accumulate or remain on the ground.
