GET OVER IT..

Yes, 'get over' is fine there, but the meaning you suggest is not correct except perhaps somewhat obliquely.

I couldn't get over ... = I was completely astonished by ... (It was totally unbelievable to me.

But it seems right to me if you want the second person to know that you cannot forget the blistering heat of dubai, considering the meaning of this phrase which is 'cannot forget' as you concurred with me too.

"Get over" does not simply mean "forget". The expression stems from recovery from an illness. You have gotten over the flu when you are back to normal. It is often used hyperbolically to show astonishment, and your example seemed to be that case, because you weren't talking about actually recovering from the heat in any way.

Like I have seen many people use, "Get over it already" - particularly urging one to not concern oneself with something that's already in the past; accept it and move on to more productive pursuits." Hence forget about what so ever befell in past.

Yes, that's right, but the implication is not so much forgetting as ignoring, changing one's attitude
