I have created a new plugin, which is basically an extension to the already available statistics regarding wind direction.
The plugin is divided into two pages. One shows monthly stats, the other one groups the data by years. What you then see is a break down of the wind direction, but rather than giving you the average direction calculated by averaging the degrees number in database, it groups data into 16 categories (N, S, W, E, NW, ….).
It includes tables, wind roses and I also got an idea of overlaying this over a Google map to allow better visualization of where exactly the wind is blowing from.
The plugin requires no installation and can be used out of the box, just adding a link to the menu.
