Some excellent advice (as always) on mozzies and sand flies here
http://www.mytobago.info/insects.php
Whilst the article is correct in advising that the little sods are active at dusk, they are also very active at first light - when it can be very still and quiet - so be prepared for a dawn assault if on the beaches early in the day.
I have to say that I am little troubled by sandflies, but those who are can react badly to their bites. Prevention is far better than cure - and less tedious / painful.
They are tiny things (also called no-see-ums by the folks from the States) and must be all mouth and teeth. My advice would be to wear trousers, rather than shorts when fishing along sandy beaches early and late in the day. They rarely fly higher than thigh height, so arms, neck, ears and face are pretty safe from attack and mozzies are rarely if ever encountered on the coast.
As Jane has mentioned, they are not a problem on the wet sand, so fishing near the water's edge, as long as it's safe too do so, is also a good method of avoidance. The trip back to the car though, can end up as a race to minimise bites, if you haven't prepared with the above advice.

Oh - weather-wise : It will be hot, with the possibility of brief heavy showers, which will occur mostly in the middle of the night. Rain cannot be ruled out during the day, so we always take a roll-up kagoul and a telescopic umberella, which can come in handy as a parasol, if the sun is too strong and there is no shade around.
