Pacific Weather Sources - On the Internet
July 2010

These are mainly for French Polynesia, westward to NZ, and northward to Hawaii.  These are all the goverment office forecast products that I have found to be useful. (and a few non-govt sites)

Global Weather Outlook from US NCEP

This is a two week outlook on major weather factors influencing the world.  It can help with longer range planning, and understanding what's making your wx happen.

New Zealand Met

Current surface analysis:

Surface Forecast Series (30, 48, 72H)

These are great maps in small (PNG) format--about 16K per map. But not easily downloadable via email (appears to be no fixed product name for the graphics, unlike other offices' websites).

Australia Met

And here's for Australia. There may be a more user-friendly page, but I found this that seems to list all the products:

NOAA Charts in Color from Hawaii
Though these are highlighted in color (much easier reading), they are small files, only about 30K each.

Current Streamline and Streamline Loop:

00, 24, 48, 72 Hr SFC Prog for Entire Pacific

Satellite Pictures

The best starting place for South Pacific Infrared Loops is here:

When I had decent internet during cyclone season in the SW Pacific, here is what I watched.  It covers from Australia to 170 W and from the Equator down to NZ.

Here is the lowest bandwidth sat picture I have been able to find.  It is likely available on a marine weather site somewhere, but this works well with crappy internet:

This picture is updated about every 15 minutes, and if you download and save successive files, you can get a fairly nice moving satellite picture.

A color version is here:

If you're looking for a really tiny (70Kb) satellite picture highlighting the ITCZ, here it is:

(there is a version every 6 hours at 0000, 0600, 1200, 1800, vary the name accordingly).  This may not be offered during non-NPac-Hurricane season, but for sure is there May-Nov

Or this is the 'current' version (I don't know how often it is updated)

FIJI Met Office

Fiji Met Office Maps and Satellite page

They have some very good products, but some of them only start coverage west of 155 degrees West.

French Polynesia Met Office

An ECMWF Model View of the Weather

The ECMWF is a different model than the GFS, managed and published in Europe.  Some say it is more accurate in the SW Pacific GRIB GFS.  Unfortunately, I don't know of a way to get it via Sailmail, and the detailed forecasts just aren't there.  However, if the GFS forecast looks unbelievable, and you have access to internet, this is a good place to cross check with a different model.

Cyclone/Hurricane Information for the Pacific

In the SW Pacific, Fiji is supposed to be responsible for forecasting Tropical Weather.  However, IMHO, they are pretty miserable at doing so.  The US Navy's Joint Typhoon Warning Center, is NOT responsible to SW Pac cyclones, but they do post info when something is happening, here:
