No may till august is off season in andamans since it will be monsoon water sports will not be stopped completely but will heavily depend upon weather and rain even the even the transport through ships and cruise from main island to other also gets affected if weather is bad
No way. It rains non-stop. When it doesn't, though that would be rare, it becomes unbearably humid. Leave July alone, c life becomes difficult from May onward even for the locals, unless you're from one of the indigenous tribes and can afford to stay without clothes. Please understand that Andaman is the only rainforest ecology left in the country that is getting fast depleted. The rains make it impossible to enjoy or, for that matter even leave for they islands as the boat services stop while planes can be risky given the weather but more importantly, there tourism interested comes to a standstill just as most of the daily life activities come to a halt during the torrential months of July and August. May and June are no better and even hotter. The best time is Oct (still very hot) to Feb or mid-March.
