It is best to aerate your turf when it is growing, expecially before applying a lawn food or topdressing. This allows the turf to grow into the aeration holes where there is plenty of water, oxygen and space. Caution should be taken if aerating when it is hot and dry. Open holes in your turf when it is hot and dry could cause the turf to suffer from drought and heat stress. To avoid this, water the turf after you aerate - Remember: Even healthy lawns can suffer from compaction, but it can be relieved through aeration.
