Campsite selection is important. However, lakes for example are not where mosquitoes breed. To hatch their eggs, they need a location that gets wet and dry. For example, a low point on a lawn that ultimately dries out an old car tire that collects rain, then dries out. The eggs are there between showers and the fresh rain helps them hatch. They can be in waiting for a long time.

As for location, misquotes prefer shade. So bushes provide a cooling place for them. Then as it is cooler at dusk or dawn, they wonder out to look for a host. So the sunnier the spot the better. But humans also like shade so you will need to compromise. But stay as far away from bushes and shade as the temps decrease as you can.

As for wind, they are not strong fliers. Consequently, wind is your friend.
