Whats the best website for forecasts of Thailand weather? I have tried a few but they all just seem to say "rain" everyday for the rainy season like now, whereas we can have a sunny morning and rain just in the afternoon. What do you use/recommend?

I wet my finger and hold it in the air.  Then I listen to what my body tells me.   

Ask a local farmer.
Far more reliable than an "official" forecast.

For accurate local weather I use Windguru. I live on Koh Samui so the wind/waves etc are useful. Very detailed but not that accurate about 4 -5 days out. The weather changes quickly here.

For general weather Accuweather is as good as any. Just set your location.

they are all similarly inaccurate. I prefer radars where you can see where the rain is moving to\from

For real time and accurate info of local and regional conditions, the Thailand Meteorological Dept site is best. 

Very deep into breaking provincial conditions, forecasts and real time updating.

For forecast I use:

https://meteologix.com/th/forecast/1609350-bangkok/xltrend

You can search for a multitude of Thai locations (seems like down to district level).

It shows forecast values (temp, rain, wind) from a range of weather centers.

I usually untick all but the "ECMWF" sites (European Centre for Medium-Range Weather Forecasts).

This is the precipitation forecast for Bangkok as an example:

True if you want to check for taking umbrella or not

Their composite is also interesting:

Currently not much around except in the deep south.

Do any of these satellite projections cover more than a 3 or 4 hours? I found "rainviewer" to be incredibly accurate for rain but its just 3 hours forecast, which does not suit my needs because I want to know what the weather will be like tomorrow morning.
