Wind from the north, temps in the 60’s, flowers starting to bloom, all good signs. This weekend should be great. Then there’s Monday where the high temp will be almost 15˚F lower than Sunday. Still no real rain on the horizon and as of today, we are almost an inch behind for the month.
Today’s surface analysis chart and sat pic provide a beautiful picture of what is going on in the Salish Sea. We’ve had the passage of a weak cold front this morning and behind this, a ridge of high pressure will start building over the area. This can already be seen by the strong northerly flow down the Strait of Georgia, through the San Juan Islands, and into Puget Sound. As with this classic situation, the best day for breeze is immediately after frontal passage. The best part is that while there may be some easing in the breeze tomorrow, there will be plenty to race with, just about everywhere. The only exception being Olympia which will remain light.
Today’s sat pic shows the clearing starting to develop over the area as well as that big low-pressure system off the coast of Oregon. It is also interesting to note on the 500MB charts that this low intrudes into the upper levels of the atmosphere. The jet stream remains to the south of this low and will drag this weakening low into California by Sunday/Monday. This is why we’ll have such a nice weekend.
The north wind course for the Blakely Rock Benefit Race can be challenging because of the proximity of the weather mark (Meadow Point) to the starting line. Particularly if there’s a flood tide. With the slower boats starting first sometimes there can be congestion at the mark. Luckily tides should not be much of an issue as a max ebb of less than half a knot will be around 1000 hrs, with the slack at around 1230 hrs. With a persistent northerly of 10-15 knots blowing overnight and then building to 15-20 knots by the time the race starts, the flood may start early by 15-25 minutes. Just watch the classes ahead to see if congestion develops at the mark.
On the run from Meadow Point to Blakely Rock the problem will be keeping your air clear as well as finding a passing lane to get around the slower boats. There may tend to be more breeze on the west side of the Sound.
Blakely Rock will be the place where most of the fleet will compress and finding clear air will be a problem. The challenge will be to stay in clear air and not having to tack too much. The overall goal will be to hold port tack and get across the Sound to Magnolia. There will be some flood at West Point so try to stay out of the current without running aground between Four Mile Rock and the West Point Lighthouse. On this leg expect the breeze to be in the 10-15 knot range from the north.
After West Point don’t tack to port immediately at the Point, instead hold starboard until you can just lay the entrance to the Ship Canal. This will allow you to avoid the flood current that accelerates along the north side of West Point. It will also allow to better judge your approach to the finish line.
The current projections for breeze have this being a fairly speedy race with the TP-52’s around in 1hr 50min, the SC-52 around in 2 hr 05 min, the J-105’s around in 2hr 27 min, the J-35’s around in 2hr 28 min, the Cal 40 around in 2 hr 42 min and the J-30 around in 2 hr and 58 min.
Have a great race, stay safe and have a good time.

He earned a Bachelor’s of Science from the University of Washington in Biological Oceanography and learned meteorology “to keep from getting kicked around on the race course.” Bruce spent nearly two decades as Associate Publisher for Northwest Yachting Magazine, retiring in mid-2015, and was the chairman of the board of trustees for the Northwest Marine Trade Association in 2014.
