• Sailing is all about the Weather.

    Big into the exploration of Atlantic Hurricanes since Katrina came uninvited into his world, James (Jim) Gurley (JamesG161) has followed every Tropical Storm birthed in Atlantic, Gulf and Caribbean waters since. Being a boater, he knows that we often need more time to prepare than we get from the TV weather folk. Jim relies on the science of storm development to share early warning info with friends and fellow boaters.

    Early in 2018, Jim and John Shepard, (JSSailem) started to chat about the weather data available. John asked Jim to help forecast Pacific NW storms, and this morphed into discussions on weather forecasting.

    For John, sailing in the PNW is sometimes hit and miss. One day is ugly, then a string of beautiful days but no wind, followed by a series of blue-sky days and 12 knot breezes. Being ready for those great sailing days means you need to look to the Pacific Ocean and what is brewing. John has been into Pacific NW Weather since the 1970’s when his first PNW November storm hit bringing more than 40 days and 40 nights of continual rain.

    Together we want to share information, new APPs, safety, and thoughts about letting the weather help you. Identify some of the resources for sailors and help prepare you for your next sailboat outing.

    It is far better to go out on the water knowing what to expect in weather terms, than to be out on the water and see dark ominous clouds suddenly appear, unprepared.

Memorial Day 2025​
​
A cool Memorial day, given the clouds and showers (which are mainly over NW WA). However, by late afternoon this holiday, temps will begin to rise, with a clearing sky. Tue & Wed this week will be exceptionally pleasant as temps rebound into the 70s to low 80s. (There is an outside chance for portions of the Willamette Valley temps to tease 90F on Wed.) A fast, weak system is on tap for Thu, so expect a one day break from the ‘almost hot’ wx; showers possible, again mainly to the north. The short week ends with another excellent warm day on the 30th.​
​
May 31 / Jun 1: Fair weather on tap, although another ’short-shot’ of clouds and rain may clip Vancouver Is area Saturday night. Generally, temps will cool down again, given a seasonally cool air mass that will move onshore and LAST through the first week of June.​
​
June 2 - 6 is trending dry & rather cool through Wed the 4th. Showers broadly spread over the entire PNW are possible on Thu, before another dry period begins, which should hold on through the weekend of Jun 7,8. Temperatures are charting as WARM, with 90s possible for SE OR; 80s elsewhere, although an onshore flow could hold back temps in the 70s west of the Cascades. Long way out, so we’ll refine the outlook as that weekend nears.​
​
Were we to pick the two warmest days out of the next ten, we’d go with this Wed and this coming Sat May 31. Overall, favorably fair wx as we transition into early Summer.​
