Best time to water your lawn: Early morning.
In the summer months, it can be hard to figure out how to water your lawn effectively. Whether you’ve set up a sprinkler system or prefer to handle lawn care manually, you’ll need to determine the ideal time of day to water your lawn.
The best time to water your lawn in hot weather is usually early in the morning before the heat of the day sets in. When you water early in the day (generally before 10 am), it allows the grass to absorb the moisture it needs before the sun evaporates the water.
When to avoid watering your lawn: Late afternoon and evening.
You should always avoid watering your grass during the hottest part of the day (typically, in the afternoons), as most of the water will evaporate before it has a chance to penetrate the soil and reach the roots of your lawn.
Watering in the late evenings also isn't a good idea. If your lawn remains wet overnight, this may encourage disease and fungal growth. To prevent this, you need to allow the grass time to dry thoroughly before nightfall, which can be hard to time properly.
The bottom line: Watering your lawn in the morning can help keep it healthy and green, even during the hottest months of the year.

Should I water my lawn every day in extreme heat?
Watering your lawn every day in extreme heat is generally unnecessary. Just make sure that your grass gets at least 1 inch of water per week during the summer. Also, remember that it’s better to water deeply less often rather than give your grass a little water every day.
Pro tip: For the best results, consider using a drip irrigation system instead of sprinklers and hoses.
