Sorry for 6 year delay
But you give only Kiev, Ukraine capital forecast link. We dont ride in Kiev (at least in 50-km zone)
We prefer play kites on Black Sea and Azov Sea near Odessa, Nikolaev, Melitopol or in flat fields Crimea area.
Usually we have no any thermal, magnetical and -al winds or thear components are lightly small. So, WINDGURU GFS works good
For example, for Crimea you can see this:http://www.windguru.cz/int/index.php?go ... 5&pu=96012
