As time passes, it is more and more difficult to maintain the old Windguru website...

All the efforts are now invested into continuous development of the new site. New Windguru features and updates require many internal changes that may cause conflicts and troubles to the old site.

Please consider switching to the new site.
It may take some time to get used to it, but you will not regret.

For all of you ultra conservative old school users ;-) I'll do my best and try to keep the old forecast display as long as possible, but please understand that it is too complicated to keep everything as it was forever.

Thanks for understanding!
