Hi, everyone.
'In the UK the hottest month of the year is usually July, whereas in southern Europe the hottest period is usually in August.'
Could you tell me whether the comma before whereas is necessary?
I have read somewhere that if a subordinate conjunction is in the middle of a sentence we should not use comma before it.
Thanks!
"Whereas" is a concession subordinator and should be preceded by a comma. That's also true about other subordinators in that group: although, while, though, etc.

silak12I have read somewhere that if a subordinate conjunction is in the middle of a sentence we should not use comma before it.That doesn't apply to conjunctions that set up contrast clauses.
Preliminary point: traditional grammar takes "whereas" to be subordinator, whereas modern grammar takes it be a preposition.
Many speakers prefer to set off contrastive adjuncts with a comma, as I just did; my advice to you is to follow suit.
