The dale was located south and east of the Trackless Sea, north of the upper Sword Coast and Spine of the World mountains, and west of the icy Reghed Glacier. While snowfall was relentless, much of it blew east to the nearby Reghed Glacier. While kinder summer months ranged from 11 ℉ to 70 ℉ (–12 ℃ to 21 ℃), the temperature of the unforgiving winters dipped as low as -40 ℉ (-40 ℃). Icewind Dale experienced freezing temperatures for much of the year.
