Climate Chart of Wainwright, Alaska, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

For Wainwright, Alaska, USA, the climate data cover 2013–2023 and show a pronounced contrast between the coldest and mildest monthly averages. The figures describe conditions across the calendar months rather than the weather on any particular day: temperatures are monthly means, while precipitation and sunshine are daily averages. The supplied pattern also includes snowfall, so winter travel planning should account for more than rainfall alone.

Climate overview

Temperature

February has the lowest monthly mean temperature at -23.1 °C, while July has the highest at 8.4 °C. These are monthly averages, not daytime highs or guarantees about temperatures on individual days, so visitors should allow for day-to-day variation when choosing clothing. Across the calendar months, the unweighted mean of the monthly temperature means is -7.7 °C; it is not a day-weighted annual average.

Snow

Mean daily snowfall is highest in October, at 5.93 mm/day, and lowest in July, at 0.17 mm/day. These are daily average amounts rather than monthly totals. They do not reveal how many days have snow, how deep any snow becomes, whether snow cover persists, or whether conditions suit skiing; the unweighted mean across the monthly averages is 2.74 mm/day.

Rain

Mean daily rainfall reaches its highest monthly average in July, at 1.68 mm/day. The lowest monthly means are tied across January / February / March, where the recorded average is 0.00 mm/day. That rounded-zero average does not establish that every day is dry or describe how often rain occurs; both figures are daily means, not monthly totals. The unweighted mean across the calendar-month means is 0.43 mm/day.

Sunshine

Average daily sunshine is highest in June, at 12.24 hours/day, and lowest in December, at 0.00 hours/day. These figures can help with planning around average sunshine duration, but they do not indicate day length or guarantee the conditions on a particular day. The unweighted mean of the monthly daily-sunshine averages is 4.85 hours/day.

Best Travel Time Guide for Wainwright, Alaska, USA: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly averages, February is the relevant reference point, with a mean temperature of -23.1 °C. Treat that as a planning guide rather than a forecast for each day, and pack for changing conditions. The lower average-rainfall option is January / February / March, tied at 0.00 mm/day mean daily rainfall; a rounded-zero average does not guarantee rain-free days or tell you how frequently precipitation occurs. If planning around rainfall, prepare for the highest mean daily rainfall in July, at 1.68 mm/day; this daily average is not a monthly total. For outdoor plans shaped by average sunshine duration, June has the highest monthly mean at 12.24 hours/day, while December has the lowest at 0.00 hours/day. Sunshine duration is not day length, and these averages cannot predict the conditions during a particular visit.

Snowfall planning is also relevant: the highest mean daily amount occurs in October, at 5.93 mm/day. This average does not establish snowy-day frequency, snow depth or snow cover, so it cannot by itself determine specific winter travel or skiing conditions.
