By not watering during mild droughts, you're actually making the root system grow stronger and healthier. Watering too frequently can harm root systems, making them more shallow and susceptible to pests.
Install a rain gauge in your yard to gather rainfall data so you know how much to water and when.
Remember that the water requirement for you lawn includes both precipitation and daily water by you. If you receive rainfall in any given week, be sure to take a rainfall measurement using a rain gauge so that you know if you can hold off watering until it is needed.
Additionally, it is important to realize that heavy rainfall isn't an absolute requirement. Your lawn won't get sick and die if it doesn't get a lot of rain every week.
Too much water in a short time period can be harmful though. If the weather forecast calls for rain, you can safely hold off on watering until a later date.
Not only does over-watering impact your water bill, it can also increase problems with insects and diseases as well. Use a rain gauge to measure rainfall so you know how much you need to apply.
When you have determined how long it takes to water your lawn, then you can adjust your watering time and sprinklers accordingly.
