Take a look at this wiz, should give you a fair idea of what it'll be like. In my experience, it's still nice and should still be quite warm relative to the UK, but can be changeable too. Also, the evenings can feel a bit chilly compared to the day (this goes for Cyprus in mid-summer too), so you'll need an extra layer if you're out at night.
