Coos County has a marine climate - mild and humid - resulting from the moderating influences of the Pacific Ocean and from the rainfall induced by the Coast Range. From March through October, the area is subject to prevailing winds from the northwest. From November through February, winds come mainly from the southwest. The Bay Area's most recent 30-year annual average shows recorded precipitation of 63.48 inches, measured at the North Bend Airport-Coos County Airport District (1961-1990). The majority of our rain falls in November (10.27"), December (10.97"), and January (9.73"). Summer months tend to be drier, particularly July (.45") and August (.96"). Temperature extremes are rare, with annual mean highs of 59.5 degrees and annual mean lows of 45.5 degrees. Given the average elevation - Coos Bay at 10' and North Bend at 16' feet above sea level - snowfall is rare. |
