Tuesday, October 27th – Lincoln County
Summary: About as predicted, yesterday was dry with sunny periods, scattered high clouds and some haze ebbed and flowed along the beaches. The thermometer was seasonal as highs reached the low-60s. After sunset, very light upper-level clouds put a thin gauze filter over the Full Hunter’s Moon but it was still brilliantly visible all night; low temps dipped to about 50F. This morning at daybreak, the Sun was battling high clouds for air supremacy and winds were out of the east at 10 mph.

Weather Factoid: What causes King Tides and where did the term originate? King Tides occur when the Earth, Moon and Sun are aligned at perigee (Moon close to Earth) and perihelion (Earth close to Sun). This alignment, which happens in Fall and Winter, causes enhanced gravitational pull on the oceans, resulting in the largest tidal ranges of the year. Conversely, the tides are reduced when Earth is farthest from the Sun in Summer. ‘King Tide’ is a colloquialism for an especially high tide, and is not a scientific term. Use of ‘King Tide’ originated in Australia and spread to New Zealand and other Pacific nations to refer to especially high tides that occur only a few times per year. The term is now used in British Columbia and the United States as well. The CoastWatch Oregon King Tide Project is in its sixth year of photographically documenting these extreme tidal events along our coast. The Winter King Tides occur earlier in 2015 than in past years; the first round of extra-high tides begins today and continues tomorrow and Thursday. Photographers are encouraged to capture images of these extreme water levels (from a safe distance) and share them here. The next series of King Tides will be November 24th-27th, and the last set on December 23rd-25th.
