Difficult one, the weather in June will be hot and humid - the weather in February will be ???
I have put ? because you just don't know, it is unpredictable this time of year and very often quite cool in the morning and evening, so if you decide on February you will probably get some lovely sunny weather without the humidity of the summer months, but you will also probably get days where it is on the cool side.
Last March when we went there were 3 or 4 days where it rained all day too.
I think weather-wise they are totally different personally, but I would prefer June myself.
