Well to the best of my knowledge, it is the end of our spring here then and the beginning of another hot summer ahead, but summer real time does not start until mid May or there abouts, it is a favourite month for many ex-pats here as the weather is tempid and not fierce heat that comes in June, July, August and even now, although we have a slight change today it is still very warm but cooler thankfully than of late.
So it can't be guaranteed perfect if your thing is beaches, leave it for later in May, but for sure it will be light years better than the UK, you may get a member now tell you it was ok when they were here in April, but I can tell you it is not guaranteed, but good all the same..
Hope this helps.
And pools will feel fairly cool as night temps will be on the low side.
