Nicola, in your opening post you have post you have identified the problem in one, wetter weather see's the grass thin. It's drainage. Lawns if they aren't spiked and air let in become compacted that's why in Autumn and spring lawns need to be spiked, lifted slightly, scarified etc and generally maintained. Where some of the previous posters have come from, no offence to any of the above, I really don't know. Lawns however you keep them need this regime, or the grass thins. Leatherjackets have hatched and flown and laid new eggs by now, but the wet is the problem.
