Every July through September, Las Vegas monsoon season rolls in with sudden downpours, hard-blowing wind, and the dust storms that turn the sky brown in minutes. For pool owners, that combination is rough. A single storm can dump enough dirt, debris, and organic material into your pool to throw off your chemistry, clog your filter, and leave you fighting algae for days. A little preparation before the storm — and fast action after — makes all the difference.
Before the Storm: Protect Your Pool
You usually get some warning before a monsoon cell hits. Use it!
- Balance your water ahead of time. Monsoon Season storms dilute and contaminate pool water. Going in with your pH, alkalinity, and chlorine already in range gives you a buffer against the swing that’s coming.
- Don’t drain the pool. It’s tempting to lower the level before heavy rain, but a full pool actually resists debris and dilution better. Empty or low pools can also float or shift in saturated desert soil.
- Secure loose items. Patio furniture, pool toys, umbrellas, and planters become projectiles in monsoon wind. Anything that can blow into the pool — or through a window — needs to be put away.
- Skip the cover in high wind. A pool cover sounds protective, but strong monsoon gusts can tear it, dump collected debris straight into the water, or damage the anchoring. In most cases it’s better to ride the storm out uncovered and clean up after.
- Turn off the equipment if a power surge is likely. Lightning and grid fluctuations can damage pumps and controllers. Shutting down protects your equipment.
After the Storm: Clean It Up Fast
The faster you act, the less lasting damage a monsoon season storm does. Dust and organic debris feed algae, and in summer heat algae can bloom within a day or two.
- Skim and remove debris first. Get leaves, dirt clumps, and larger material out before they sink and dissolve. The longer they sit, the more they load your water.
- Empty the skimmer and pump baskets. Storms fill them fast, and a clogged basket kills your circulation right when you need it most.
- Brush and vacuum. Fine desert dust settles into a silty layer on the floor and steps. Brush it loose, then vacuum — to waste if the load is heavy — so it doesn’t overwhelm your filter.
- Test and rebalance. Rain lowers pH and dilutes chlorine, while debris raises the chlorine demand. Retest everything and correct it.
- Shock the pool. After a significant storm, shocking knocks out the contaminants and organic material that fuel algae before it gets a foothold.
- Check and clean your filter. A storm can pack a filter with fine grit. Backwash a sand or DE filter, or hose off a cartridge, so it can actually do its job.
Stay Ahead of Monsoon Season
The owners who sail through monsoon season are the ones who don’t wait for the water to turn green. During July through September, tighter maintenance — more frequent testing, quick post-storm cleanups, and keeping chlorine on the higher end of the range — keeps small problems from becoming expensive ones.
