NOT FOR NAVIGATION The accuracy of these tide predictions is not guaranteed in any way. You should not use this program if anyone or anything could come to harm as a result of an incorrect tide prediction. NOAA and similar agencies in other countries can provide you with certified tide predictions if that is what you need.
XTide's predictions do not incorporate the effects of tropical storms, El Niņo, seismic events, subsidence, uplift, or changes in global sea level.
Cathlamet, Washington - IGNORE HEIGHTS 46.2000° N, 123.3833° W Note: The Columbia River is subject to annual freshets. Short range predictions are available at local river forecast centers. The data for stations above Harrington Point apply only during low river stages. There is a tidal influence along most of the length of the Columbia River. However, that influence becomes smaller at greater distances from the Pacific Ocean. We are able to provide predictions of the times and height of tides from the Columbia River Entrance to Harrington Point, Washington. Above Harrington Point, although there is still a tidal influence and we can predict the times of the high and low tides, the water levels experienced are more a result of freshwater flow in the river than the astronomical tides. It is for this reason that the heights of both high and low tides along the Columbia River, above Harrington Point, are set to a value of 0.0 feet. Heights for this station should be disregarded--use times only.
