☀️ August Weather Outlook and Best Watering Practices 🌿
El Niño Has Officially Arrived!
As we head into August, Southeast Michigan is looking at classic late-summer weather: daily temperatures reaching into the mid-80s, higher humidity, and sporadic pop-up afternoon thunderstorms mixed with many dry stretches.
While those brief summer rain showers may help, they usually aren't going to be enough on their own. Combined with high heat and humidity, these conditions can put significant stress on cool-season lawns and landscape plantings.
Here is what you can do on your end over the next 30 days to keep your turf and landscape healthy, hydrated, and resilient:
💧 1. Adjust Your Watering Strategy
Water deeply, but less often: Aim for 1 to 1.5 inches of water per week (including rainfall) delivered over 2–3 mornings rather than light daily watering. Deep watering encourages roots to grow downward where soil stays cooler.
Time it right: Water early in the morning (between 4:00 AM and 9:00 AM) so the soil absorbs moisture before the afternoon sun evaporates it. Avoid watering late in the evening—leaving grass blades wet overnight in high humidity creates the perfect environment for fungal diseases like brown patch.
🕒 How long should you run your sprinklers?
Standard Spray Heads: Aim for 20–30 minutes per zone, 2–3 mornings a week.
Rotor Heads (rotating spray): Aim for 35–50 minutes per zone, 2–3 mornings a week.
💡 Pro Tip: Place a few empty tuna or cat food cans on your lawn and run your system for 20 minutes. Measure the depth with a ruler to pinpoint your exact precipitation rate!
⚙️ 2. Check Your Sprinkler System & Beds
Inspect spray patterns: Take a walk around your yard while your irrigation is running to ensure heads are aiming at the lawn and not wasting water on driveways or sidewalks.
Watch for "doughnut" spots: If you notice grass that is dark green and tall immediately around a sprinkler head, but dry a few feet away, that's a classic sign the head isn't popping up high enough to clear the surrounding grass blades.
Maintain mulch depth: Check that mulch levels around shrubs and flower beds stay at 2–3 inches to help root systems retain moisture and stay cool during heat waves.
🚿 3. No Irrigation System? No Problem!
If you don't have an automated sprinkler system, you can still keep your lawn healthy through the hot stretch with a simple hose-end sprinkler setup:
Use an in-line water timer: Screw an inexpensive mechanical or digital hose timer onto your outdoor spigot. You can set it to turn on automatically early in the morning so you don't have to wake up at 5:00 AM to move the hose.
Target 20 to 30 minutes per zone: Move an oscillating or impact sprinkler around your yard in sections, running each area for 20–30 minutes every 3–4 days rather than short daily sprinkles.
Prioritize high-stress spots: If watering the whole lawn manually isn't realistic, focus your efforts on full-sun areas, slopes, and grass along hot concrete driveways or sidewalks that bake in the afternoon heat.
