PW is using the standard models and selectively presenting them.

Re: PassageWeather.com - Wind and Wave Forecasts for Sailors and Adventurers

Paying for data that you get for free makes no sense to me. I have been using Weathertracker on my iPad. Basically same data but it's for free. The Metrogram is the best part.

I'm just getting ready to add some new forecast regions to the NW Pacific, so your timing is perfect.

I was thinking of Japan down to the Philippines and east almost to Hawaii... What would you recommend?

Re: PassageWeather.com - Wind and Wave Forecasts for Sailors and Adventurers

I like and use Passageweather while on board. One thing I appreciate is the low bandwidth it requires. Services like windytv are great, but require a lot more data and bandwidth than PW.

All of Micronesia; include Palau, the FSM, Guam and the Northern Marianas, the Marshalls and Kirabati. Thanks very much for the consideration! More options is a good thing.

I agree, especially windytv, which is very bandwidth intensive; windgugu, not so much so. I'll be interested to try out the new weather app on the Iridium Go! when I get a new one later this year.

How does this look to you?

Here's the whole forecast page: PassageWeather.com

It's still missing Sea Temperature but they will be available tomorrow.

This!

Passageweather is excellent. The data is available in many places, but PW is the best I've seen for usability and sensitivity to bandwidth challenges of cruising sailors. The main site is already bandwidth optimized, and you can choose an alternative, super low bandwidth portal for downloading files without viewing anything.

Kudos to the developers; PW is a great site, and for many years my own go-to site for GRIBs and other raw model output weather data.

Right you are. I was getting "Predictwind" mixed up with "Passageweather". My comments were about Predictwind. Apologies to Passageweather.
