Thanks for taking this on, Walt. We concur with Ian, we like the box with the wind speed, direction and gusts. That's what we mainly use. People visiting from other locales would appreciate air temperature and the rest of the data. Tidal current and tide heights are nice, but we have that on our phones.
Because we use 13" laptops and iPads the more you can keep on a single page without having to scroll down, the better.
Is a web cam out of the question? There is one we like on top of Corinthian Island that shoots a still shot every 5 min and has the air temp, barometer and windspeed and gusts superimposed on the image. Here's the link, it is the 3rd image down on the page: http://www.rntl.net/tiburoncam.htm
