I stumbled upon an amazing weather forecast and history webpage that updates every couple of minutes. Great features, like this very detailed history of 2012.
Weather History for Weather Station ICHONBUR5 | Weather Underground
Seems there is a weather station in Jomtien where the Thappraya Road turns left to Jomtien Beach that's independent from the Thai weather station near Royal Cliff in South Pattaya, and that it opened on the 14.01.2012. There are no earlier records. From this date until the end of the year it counted 865.9 mm of rain. From the start of this year until now 188 mm. The bloody place is not in the tropics, it's a frigging desert. Anyway, when you click on 'maps and radar' on the top and then 'Asia', this map indicating where cloud cover and rains are is updated every couple of minutes also. There are probably more features I haven't found yet. Here is the Pattaya forecast,

It says 90% rain probability tonight. Very funny.
