NGA Pilot Charts, URLs for direct downloads
 
Please PM me any updates / broken links so I can keep this list current.

Copied from www.nga.mil:
Pilot Charts depict averages in prevailing winds and currents, air and sea temperatures, wave heights, ice limits, visibility, barometric pressure, and weather conditions at different times of the year. The information used to compile these averages was obtained from oceanographic and meteorologic observations over many decades during the late 18th and 19th centuries.

The Atlas of Pilot Charts set is comprised of five volumes, each covering a specific geographic region. Each volume is an atlas of twelve pilot charts, each depicting the observed conditions for a particular month of any given year.

The charts are intended to aid the navigator in selecting the fastest and safest routes with regards to the expected weather and ocean conditions. The charts are not intended to be used for navigation.

The Atlas of Pilot Charts of the South Atlantic Ocean and the North Pacific Ocean(NGA Pubs 105 and 108, respectively) are not yet available for download, as they are still awaiting digital conversion.

The information used to compile these averages was obtained from oceanographic and meteorologic observations over many decades during the late 18th and 19th centuries.

If I read that right, the data is over 100 years old? I'm sure it is still pretty darn good information and I realize these are averages, but the climate has changed somewhat in the last 100+ years. Is there any updating going on?

Anybody have any insight on if/when the North Pacific Charts are every going to be digitized by NGIA?
For now this guy:http://www.nomadelectronics.com/Family/Serenade/PilotCharts/PilotCharts.htm has done a portion of the N. Pacific.

Thanks for this link. It does not quite work - it takes you to his main page.

Try North Pacific Pilot Charts for the pilot charts page.

Pilot Charts
 
There are also so called "Next Generation " Pilot charts...in fact Grib files compiled from actual weather for every month from 1990-1999.

I tried to upload one here, but the forum seems to only allow pictures files

Cheers

Alan

Grib file pilot charts
 
The other problem is that they are for each hour of each day of each month for 10 years...120Mb in total....so I can't email them....

If anyone has an ftp server that I could up load them to for general distribution, I'd be happy to do that

Cheers

Alan

Hello,
The links posted above do not seem to work anymore. Does anyone know where we can possibly download thes NGA digitalized pilot charts ?
Thanks much !

I was able to get a top-level menu from

Maritime Safety Information

And also downloaded December's North Pacific pilot chart (haven't tried any others).

Many thanks Adam, this is quite helpful.
