When it comes to how enjoyable offshore sailing is, nothing matters more than the weather. Today we are going to talk about which iPad (and computer) applications are best for receiving weather both with high speed internet, and with low bandwidth equipment like satellite phones and HF radio. We'll also talk about the best FREE apps, and the best PAID apps.

I can recommend a couple of older books that are useful to cruisers that we have found helpful: "Mariner's Weather Handbook" and "Surviving the Storm", both from 1999 by the Dashews (Steve and Linda). The latter should be in every cruiser's library. Although we have some nicer tools now than weatherfax (still important), his advice and case examples are still good, imho.

Great video. We have used Predict Wind standard for cruising from Pensacola to the Keys/Bahamas for the last three years. The passage planning is great for picking the window (from four sequential days). After picking the day, you have the four models to review for the passage plan. (The CAPE model is also helpful to forecast the potential convective activity.) Predict Wind is very accurate and it's fun to compare the models along the passage.

As well I have a minor in geography from Southern Illinois University which had a weather component to it. I am a bit of a weather nerd so, I love what your are talking about and understand just how important weather data is before you go on voyage across the ocean. I am coming to you from Turks and Caicos, Seven Stars Resort and Spa. Doing some Scuba tomorrow and am looking forward to getting under the water. But had to look at the weather data to get back out on the water... Good look to getting back to Clarity when you do. Be safe and we look forward to your next videos.

Saw the beginning and thought that looks like the PNW coastal range and sure enough... Fun discussion on the weather app and models at the end. Very valuable to get into the geek level detail questions with the designer. Having sailed in the sound and Hood's canal the thermals are always a thing. Sailing near land mass especially with mountains and the cool water below you learn quickly to pay attention. You can run up/down a coastline avoiding general offshore wind/current trends if there is a local variation that is favorable. This is also true on the east coast where I am now. I get interior wind patterns plus thermals until I get closer to the ocean and then there is confused wind and then the offshore trend dominates.

Thanks so much for this well produced and structured video. As a long time pilot I have slightly more understanding than the average Joe (only slightly) but of course my predictive capacity is improved by the average very short window needed for a safe flight and restricted to the areas well above the surface. People rarely appreciate the incredible complexity of these models and the dependency on limited data collection ability especially offshore! I have only sailed offshore a few times and that was a number of years ago when these models and apps were not available. It was hold your wet finger up and look at the wind vane and barometer. Scary stuff sometimes. Thanks again for the video and the info on the available predictive software that can now significantly improve both my knowledge and my peace of mind. Stay Safe.

@TheOKellys 3 жыл бұрын

There are a lot of positive feedback processes in the real atmosphere...”nonlinearities” we call them. Too many and too detailed to get into here. But bottom line, in the real atmosphere, little things can have tremendous effects. So the geniuses who build these models try to capture these nonlinear processes, but they can be “too sensitive” in some circumstances and the model solutions get out of control with feedback loops sometimes. That’s what we mean by blowing up. Now this happens with all models all the time, and so there are “smoothing” algorithms applied at some grid scales and time scales in an effort to keep things reigned in....but that can go too far as well.... So the best models for any particular kind of initial conditions are best at “attenuating” these nonlinear processes realistically. It is a very difficult task for any model.

exactly. anyone who says..."hey the model was wrong"....just doesn't understand how models work or how to forecast. For the foreseeable future, a human being is required to make a good forecast.

Can you suggest a resource for learning more about the impact of upper atmosphere interaction with weather systems, specifically the 500mb level winds? I understand the 3 dimensionality of the nature of the air stream and the divergence/convergence with low/high pressure systems, but how do we use that to anticipate whether a system will intensify or be stable? I have Steve Dashews Weather Book that discusses it, but that's about it. I use earth null school for watching the air stream at 500mb and how the circum-polar lobes extend into the 30 latitudes, but I don't get the "so what?" yet.

GREAT video! Based on your experience at what duration of passage does adding Iridium or other satellite service become very important for updating weather while underway? A forecast obtained at departure might be great for the first two days, but then accuracy would progressively decline.

We feel pretty naked without satellite connection for more than a couple days. But it depends on the time or year and location. In the trade winds, I’d probably feel ok with a three or four day passage without satellite, but in the substropics or mid latitudes, more than 72 hours without weather would bother me a little.

Fantastic, you should post this in aviation blogs as well. Also for your pilot friends, what can you pull out of ForeFlight useable for sailing?

Man, it is completely different. Everything in aviation is soooo much more structured, from nav to weather to planning.... If people had to operate boats like you do planes, no one would sail.

I agree on the structure comments by Nick! When I was just a VFR (visual flight rules) pilot it was more fun. When I became IFR and type rated in a jet I was safer but flying became less about flying and more about procedures and weather. As far as Foreflight, there would be (as Nick stated) more data to add to your data pile. But for what (I think) you would get out of it and for the effort likely a minimal benefit. So for me 2 thoughts here, if conditions are dicey enough to substantiate digging into foreflight one probably should make the “no go” decision and wait for a better window. On the other hand, if I was stuck in a really bad situation I would use any data available. Lastly, one thing I find very useful in aviation is Pireps. With weather forecast already being analyzed I find actual accounts of reported conditions along my route very helpful. In aviation We have such a shorter time of exposure. I’m not yet experienced or have a solid education in weather for sailing. I see that many Pireps my be used in the models supplied now. Could be a benefit to have current reports plotted on the map for consideration? Another thing aviation has available is routes used by other pilots recently. FLTPLAN make suggestions on routes base upon other flights made recently. Possibly this is a consideration already given inside PredictWind’s routing? Idk. Nick finds these things out! Great video and thank you for sharing your knowledge with us. I’m not ready but I can promise I’ll be watching all your video’s on weather and gaining more knowledge until I’m more confident!!

ForeFlight is an awesome app by the way. 👍

ShipReps are a thing already, and I talked to a gent from NHC about a program to incorporate more of those from small vessels. No timeline, but that really will make a difference. Suggested routes....now there could be issues with that as bottom contours change a lot over time, especially in shallow areas. Not so much an issue in the skies....

That will be very useful to everyone but possibly more value to someone like me learning. If I’m lucky enough to experience doing a crossing it would reassuring to see actual reports substantiate the weather I’m pulling down. Actual observations are valuable and mostly very accurate but caution still needs to be taken. Example: I was descending into Dallas, was given by the tower while on final, the aircraft just front of me were reporting taking on ice from 2500’ to 2000’ melting and shedding off after descending through 2000’ and before landing. We took ice starting at 2000’ and all the way to the ground. Landed with ice. Lesson: information is good but still not guaranteed. This was maybe 5-10 minutes difference in time.
