HOW MONSOON RAIN AFFECTS YOUR POOL & HOW TO FIX IT 🌧️💦

Arizona’s monsoon season brings heavy rain, dust storms, and strong winds—all of which can wreak havoc on your pool. A quick downpour may seem harmless, but monsoon rains dilute chlorine levels, lower pH, and introduce dirt and debris, creating the perfect storm for algae growth and cloudy water.

So, what does monsoon rain do to your pool, and how can you fix it? Let’s break it down!

HOW MONSOON RAIN AFFECTS YOUR POOL

Arizona pools face unique challenges during monsoon season. When rain, wind, and dust mix, your pool water can quickly become unbalanced and unsafe for swimming.

Here’s how monsoon rain affects your pool:

✅ pH Levels Drop – Monsoon rain is naturally acidic and can make your pool water too corrosive, leading to skin and eye irritation and potential damage to pool equipment.
✅ Chlorine Gets Diluted – Heavy rain lowers chlorine levels, making it easier for bacteria and algae to thrive.
✅ Algae Blooms – Rain runoff from your yard brings in phosphates and nitrates, which feed algae and turn your pool green.
✅ Dust & Debris Build-Up – Monsoons stir up dirt, pollen, and leaves, which clog filters and make your pool water cloudy.

💡 PRO TIP: The stronger the monsoon, the bigger the impact on your pool’s chemistry. Acting fast will help prevent long-term issues.

CAN YOU SWIM IN YOUR POOL AFTER A MONSOON?

Not right away. Your pool water may look fine, but its chemical balance is likely off. Before diving in, take these safety steps:

✔ Check for debris – Remove leaves, dirt, and branches.
✔ Test chlorine & pH levels – Rain likely diluted chlorine, increasing bacteria risk.
✔ Look for cloudy water or green tint – This could mean algae growth is starting.

If your water is clear and chlorine levels are balanced, it should be safe to swim. If it looks murky, green, or foamy, you’ll need to treat it first!

HOW TO FIX YOUR POOL AFTER A MONSOON

If a monsoon storm just hit Queen Creek, here’s what to do before problems get worse:

🧹 STEP 1: SKIM & REMOVE DEBRIS

Monsoon storms bring in leaves, dirt, and branches, which can clog filters and lead to bacteria buildup. Skim your pool right away and clean out skimmer baskets.

💦 STEP 2: DRAIN EXCESS WATER

If rain caused your pool to overflow, drain the water back to normal levels before adding chemicals.

🧪 STEP 3: TEST & BALANCE CHEMICAL LEVELS

After a monsoon, your pool’s pH, chlorine, and alkalinity may be way off. Use a test kit or have a professional check your water.

✔ pH should be between 7.2 – 7.6
✔ Chlorine should be 1-3 ppm
✔ Alkalinity should be 80-120 ppm

If levels are too low, your pool will become a breeding ground for bacteria and algae.

⚡ STEP 4: SHOCK THE POOL

If chlorine levels are too low, you may need to shock the pool to kill bacteria and algae spores introduced by the rain.

✔ Use liquid chlorine or calcium hypochlorite shock
✔ Double or triple the dose if your pool is starting to turn green
✔ Run the filter continuously for 24-48 hours

💡 PRO TIP: Shocking at night prevents Arizona’s intense sun from burning off chlorine too quickly.

🌀 STEP 5: RUN THE FILTER & BRUSH THE POOL

Let your filter run for at least 24 hours to clear out debris and chemicals.
✔ Brush walls & steps to remove dust and early algae growth
✔ Backwash or clean your filter to improve circulation

HOW TO PREPARE YOUR POOL BEFORE MONSOON SEASON

Monsoons can’t be stopped, but you can protect your pool from their worst effects!

✔ Keep water balanced – Well-maintained pools recover faster from storms.
✔ Trim trees & secure loose items – Prevent branches & furniture from landing in the pool.
✔ Cover your pool (if possible) – A pool cover blocks out dust & debris.
✔ Shock your pool before heavy storms – Prevents chlorine loss & algae growth.
