go swimming

I'm gonna go to the pool near my house from right now on!
It's too hot today, so I'd very much like to swim so much.

I'm going to explain this from a perspective of someone who speaks Japanese (I'm not that fluent in Japanese yet but I assume, that this translation is coming from an original Japanese language)

For the first sentence, I think you're translating it from 'ima kara' which would translate in English as 'from now on'. However, using 'right now' sounds more natural. For the second sentence, you are emphasizing that you'd like to go to swim very much.. The sentence is actually already ok but I just put how I'm going to say it if it were me.
