I made a table that shows the predicted time to the Equator (according to different GFS models to follow weather development)

Times are rounded to 1 hour because of the 1-hour router step in 5 days.

http://zezo.org/jv/times.html

Should update with new data around 05:05, 11:05, 17:05 and 23:05 UTC

It needs a bit of css work. Maybe links to the chart with different times. Suggestions are welcome.

one major update I think of could be to color with one easily eye-catching color the best values...

Or to allow to download a CSV version so we can use a spreadsheet app to do it locally.

I thought about something like yellow below 140 and green for 130 or so.

It would also be nice to have some graphs that plot the time ;-)

The original data files look like this

cat pred/1542369600.txt
1542387600 150
1542391200 150
1542394800 150
1542398400 149
1542402000 149
1542405600 149
1542409200 149
1542412800 148

file name is the GFS stamp in unix time() format, as is the first field in the file. I can make them visible on the web server if someone is interested.

The times are to the equator, while sailing towards Fernando de Noronha.

But it's not the time the track crosses the Equator, just when the isochrones reach it. Which may happen East or West of the intended trajectory.

This is a great help, thanks a lot!
I was drifting through Biskaya too lazy to look for a good start time but now I think I have to go for a try. 130h to the equator looks too tempting.

The chart links should probably use ?st for the start time, not ?t.

Yep. That's what happens when you write code with a toddler running around you in circles ;-)

There is a related bug - the drop-down does not have the 1-hour increments so it shows "Start now" for them.

Maybe the first 48 hours should be on 1-hour intervals in the chart too, but then we hit another issue - the wind display is in 3 hour steps too.

Thank you! Substantial time saving, I (and others players i suppose) did the same thing few times a week.
Good for the server load also.
