September marks the transition from summer to autumn in Greenland. Coastal regions experience average temperatures hovering around freezing, ranging from -1C to 4C (30F to 39F). Inland areas, particularly at higher elevations, see significantly colder conditions. Precipitation shifts from primarily rain in the coastal south to a mix of rain and snow further north and inland. Decreasing daylight hours become noticeable as the month progresses.
Understanding Greenland’s climate during this period is crucial for various activities. Planning travel, research expeditions, and assessing environmental changes all require accurate climate information. Historically, September offered a window for exploration and trade before the harsh winter set in. Contemporary observations contribute to long-term climate studies, providing insights into the effects of global climate change on this sensitive Arctic region.
