You can over seed any time, but if you lay down a pre-emergent in the spring dont over seed till fall. Like i said though you can over seed whenever. Just make sure your client knows it is very important to water at least once a day for 30 days for all the different types of grass in the seed mix to germinate. It would be best if they would water twice daily but good luck with that.
Try to avoid the very hot parts of the year due to thew whole water thing and usually watering bans or restrictions.
