Solomon Islands
The Solomon Islands lie just east of Papua New Guinea and northeast of Australia. The were the site of some of the most influential battles in the Pacific Theater in World War 2, most notably the Battle of Guadalcanal. Guadalcanal is the home of the capital Honiara and the largest island in the Solomons. The islands lie surrounded by ocean, lie in the tropics and have little in the way of substantial elevation changes. This means that there is little variation through the course of the year. The Islands are hot and humid through the year, with a tropical season from about April to November.
The Solomons have a website for their Solomon Islands Meteorological Agency, a rarity in the south Pacific. While it's a coding nightmare, the forecasts (found on the right hand side of the screen) are valid. Other than that, like I said, if you know anything about HTML, there is an outfit in the Solomons that could use your help.
