Introduction
Arizona’s monsoon season (June through September) brings dramatic dust storms, flash floods, and torrential rain that can wreak havoc on your swimming pool. If you’re a Phoenix, Scottsdale, Mesa, or East Valley pool owner, proper monsoon preparation isn’t just recommended—it’s essential.
At PHX Pool Crew, we’ve serviced thousands of pools through Arizona monsoons, and we’ve seen firsthand what happens when pools aren’t properly prepared. From green water disasters to damaged equipment, the costs of neglect far exceed the investment in prevention.
This comprehensive guide will walk you through everything you need to know to protect your pool investment during monsoon season.
Why Monsoon Season is Different for Phoenix Pools
The Triple Threat:
1. Dust & Debris Storms
Monsoon winds can dump pounds of dust, leaves, and debris into your pool within minutes. This organic matter feeds algae and clouds your water fast.
2. Heavy Rainfall
Intense rain dilutes your pool’s chemical balance, drops pH levels, and can overflow your pool, causing drainage issues.
3. Extreme Temperature Swings
Arizona’s summer heat combined with sudden cool monsoon storms creates ideal conditions for algae blooms.
Pre-Monsoon Checklist: 7 Steps to Protect Your Pool
1. Deep Clean Before Storm Season (Late May/Early June)
Start your monsoon prep with a thorough pool cleaning:
- Acid wash if you haven’t done one in 2+ years
- Vacuum all debris from pool floor
- Brush walls and tile line to remove buildup
- Clean filter thoroughly (backwash sand/DE, clean cartridges)
- Empty skimmer and pump baskets
Why it matters: A clean pool is more resilient to chemical imbalances caused by storms.
2. Balance Water Chemistry Perfectly
Before monsoon season hits, get your water chemistry dialed in:
Ideal Pre-Monsoon Levels:
- pH: 7.4-7.6 (slightly higher to buffer rain dilution)
- Alkalinity: 100-120 ppm
- Chlorine: 3-5 ppm
- Cyanuric Acid: 50-70 ppm (higher for extra UV protection)
- Calcium Hardness: 250-350 ppm
Pro Tip: Shock your pool 24 hours before a predicted storm to give chlorine levels a head start.
3. Upgrade Your Pool Cover or Get a Safety Net
While full pool covers aren’t practical in Phoenix heat, consider:
- Fine mesh safety nets to catch large debris
- Automatic pool covers (if your budget allows)
- Pool leaf nets for quick deployment before storms
Investment: A quality leaf net ($50-150) can save you hours of cleanup and hundreds in chemicals.
4. Check Drainage Systems
Phoenix pools need proper drainage to handle monsoon overflow:
- Install or verify deck drains are clear and functional
- Check pool overflow drainage isn’t clogged
- Ensure deck slopes away from your home’s foundation
- Test sump pumps if you have them
Warning: Poor drainage can cause pool water to overflow onto your property, potentially causing thousands in damage.
5. Secure Pool Equipment
Monsoon winds can damage exposed equipment:
- Anchor shade structures or remove temporary ones
- Secure pool furniture or store indoors
- Cover pump/filter motors with waterproof covers
- Check electrical connections for GFCI protection
- Store loose cleaning tools in your pool shed
6. Trim Surrounding Trees and Plants
Don’t wait for a storm to discover which branches can reach your pool:
- Trim overhanging trees at least 10 feet from pool
- Remove dead branches that could fall during winds
- Cut back bushes that shed leaves into the pool
- Consider wind barriers like fencing or landscaping
East Valley Tip: Palo verde trees are beautiful but drop massive amounts of debris. Keep them trimmed!
7. Stock Up on Pool Chemicals Early
Monsoon season = algae season. Stock up before everyone else:
Essential Storm Season Supplies:
- Liquid chlorine or shock (extra supply)
- Algaecide (copper-free for plaster pools)
- pH increaser (storms lower pH)
- Clarifier (for cloudy water post-storm)
- Test strips or liquid test kit
Pro Tip: Buy in bulk in May when prices are lowest and supplies are plentiful.
During a Monsoon Storm: What to Do
Safety First
- Never swim during or immediately after a storm (lightning risk)
- Shut off power to pool equipment if flooding is likely
- Stay away from pool area during high winds
Quick Actions
If you catch a storm warning with enough notice:
- Super-chlorinate (double shock) 2-4 hours before storm
- Run pump on high for 2 hours before storm hits
- Lower water level 2-3 inches if heavy rain predicted (if safe)
- Deploy leaf net if you have one
- Turn off heater to prevent damage from power surges
Reality Check: Most monsoons hit with little warning. Don’t risk your safety trying to prep during a storm!
After the Storm: Recovery Protocol
Immediate Actions (Within 24 Hours)
1. Remove Large Debris
- Use a leaf rake or net to remove branches, leaves, and debris
- Don’t let organic matter sit—it feeds algae fast
2. Test Water Chemistry
Storms will throw your balance off:
- Test pH, chlorine, and alkalinity
- Expect pH to drop (rain is slightly acidic)
- Chlorine will likely be depleted
3. Shock the Pool
- Add shock treatment (calcium hypochlorite or liquid chlorine)
- Use 2 lbs per 10,000 gallons (double normal dose)
- Run pump continuously for 24 hours
4. Add Algaecide
- Add preventive algaecide even if water looks clear
- Copper-free formulas are safest for plaster/pebble pools
5. Clean or Backwash Filter
- Storms put extra strain on filtration
- Clean within 48 hours of storm
Next 3-5 Days
- Test water daily until chemistry stabilizes
- Brush walls and floor every other day
- Run pump 12+ hours per day (or 24/7 if water is cloudy)
- Monitor water level and adjust if needed
If Your Pool Turned Green
Don’t panic! Green pools are common post-monsoon:
- Brush pool thoroughly
- Test and balance pH first (7.2-7.6)
- Triple shock (3x normal dose)
- Add copper-free algaecide
- Run filter 24/7
- Brush daily for 3-5 days
- Vacuum to waste once algae settles

Frequently Asked Questions
Q: How much rain will overflow my pool?
A: Typically 2-3 inches of rainfall can cause overflow in most Phoenix pools. Arizona monsoons can drop 1-2 inches in an hour.
Q: Should I drain water before a monsoon?
A: Only if major flooding is predicted. Otherwise, keep water at normal level. Don’t drain below skimmer opening.
Q: Can I shock my pool during a storm?
A: Only if safe to do so 2-4 hours before the storm. Never handle chemicals in lightning/wind conditions.
Q: How long until my pool is swimmable after a storm?
A: Typically 24-48 hours after proper chemical treatment. Test chlorine levels first—should be 1-3 ppm.
Q: Why does my pool turn green after every storm?
A: Low sanitizer levels + organic debris + diluted chemistry = perfect algae conditions. Prevention is key!
Q: Is a green pool dangerous?
A: Yes. Green pools harbor bacteria and can cause skin/eye infections. Don’t swim until properly treated and clear.
Conclusion: Be Proactive, Not Reactive
Phoenix monsoon season doesn’t have to mean pool disaster. With proper preparation, consistent maintenance, and quick storm response, your pool can stay crystal clear all summer long.
Key Takeaways:
✅ Prepare in May/early June before storms hit
✅ Keep chemical levels slightly elevated during monsoon season
✅ Act within 24 hours after each storm
✅ Invest in weekly professional service if you value your time
✅ Stock extra chemicals and supplies in advance
Remember: The cost of prevention is always less than the cost of cure. A neglected pool after one major monsoon can require $500-1,000+ in recovery services.
