hi steve...

here's another one

for those who lives near great lakes (as i do) or oceans,is there a way to calculate waves height in feet or meter(estimation) based ond wind speed? and add it on the main screen and html tag?

maybe this could help:http://oceanworld.tamu.edu/resources/oc ... r16_01.htm

cheers

There's a simple approximation using the Beaufort scale, but this only applies in open sea. There are many too many other factors affecting wave height close to land.

Hi every one. :D I know this data can be found at NOAA. but this is a physical reading, and probably a much "safer one", to go by. You can also "dial a bouy" at, http://www.ndbc.noaa.gov/dial.shtml. The info could be estimated, I suppose, but has to accurate for safety reasons.

Hi,

For anyone looking at NOAA pages they have noticed they also have integrated a RSS feed from each buoy location that not only gives wave data but shows ships that are transmitting weather data from within 100 N Miles from each location.

For example right now there is a ship 99 miles from the buoy which reports:

Significant Wave Height: 10 ft
and Dominant Wave Period: 5.0 sec


While the buoys reports:

Significant Wave Height: 8 ft

It's easy enough to display this data on a web site.

See my own site weather page as an example:http://url.ie/1zpb

The left column is the weather buoy and the main content is my own station data.

My RSS data is from: http://www.ndbc.noaa.gov/station_page.php?station=62092

All the best Dave
