Laurel Mountain (Oregon)

Climate

Laurel Mountain has a hyperhumid maritime climate, on the border between Mediterranean (Csb), oceanic (Cfb) and subpolar oceanic (Cfc/Csc). Rainfall is extremely heavy between October and April, and even in the dry months of July and August fog is very frequent and prevents soils and vegetation from drying out appreciably. In November 2006 the mountain received over 49.59 in of rain – six days were lost due to gauge overflows – and in the record wet December 1996 throughout the Pacific Northwest 49.57 in.

Despite winter temperatures being above freezing on an average 72 of 89 afternoons – and minima above 32 F on 31 mornings during a typical winter – precipitation is so heavy that snow cover in an average January reaches 9 in, whilst the record seasonal snowfall is 323.50 in between July 1998 and June 1999. Since 1978 extreme temperatures have ranged from −11 F on December 24, 1983, to 94 F on July 22 of 2006, though in the thirty-five years of record only fourteen minima below 0 F have been recorded. |Jan record high F = 78 |Feb record high F = 70 |Mar record high F = 70 |Apr record high F = 78 |May record high F = 87 |Jun record high F = 90 |Jul record high F = 94 |Aug record high F = 92 |Sep record high F = 90 |Oct record high F = 85 |Nov record high F = 73 |Dec record high F = 68 |year record high F = 94 |Jan avg record high F = 56.5 |Feb avg record high F = 56.5 |Mar avg record high F = 57.6 |Apr avg record high F = 64.7 |May avg record high F = 74.1 |Jun avg record high F = 77.3 |Jul avg record high F = 83.8 |Aug avg record high F = 84.4 |Sep avg record high F = 81.5 |Oct avg record high F = 72.7 |Nov avg record high F = 60.7 |Dec avg record high F = 55.4 |year avg record high F = 87.0
