The Wall has been fickle this year with both the Maryhill and Marker 40 sensors often promising ideal WSW wind for The Wall but actually only delivering reliable wind to the Oregon side of the river.
But yesterday the overall wind in The Wall region was more WSW rather than W-WNW by mid-morning. This type of flow negates the local venturi that can fool the sensors. So strong wind spanned the river.
My website has lots of photos of both hot shots and regular good sailors enjoying silky swells at The Wall.
One of the most common questions I get in the Gorge is how to know when it is worth the long drive to The Wall.
Until about 5-6 years ago the rule for many was to look for about 27 knots and 230 degrees (about WSW) on the Maryhill sensor. The actual wind on the water would be weaker than that but it would typically be strong and filled in across the river by the time you arrived at The Wall.
But in more recent years there has been a decreasing frequency of SW-WSW wind and an increasing frequency of W-WNW summer wind for much of the west coast. This has impacted sites that need SW flow such as Sherman Island Powerlines, Larkspur Landing and The Wall.
This blog shows some of the new rules for The Wall I have been researching. The critical thing is to not fully trust the current M40 or Maryhill sensors near The Wall until they get over 34 knots. They are accurate for their Oregon side locations but they now often pick up very local venturi wind that is ONLY on the Oregon side.
