Phoenix Reached 114 Degrees on August 25 - Now Valley Pools Are Showing the Wear
Scottsdale, United States - October 15, 2026 / Optimal Pool Care /
Arizona just completed its hottest summer on record, and Valley homeowners are now discovering the consequences in their backyards. Scottsdale-based Optimal Pool Care reports that repair and cleanup service calls have increased since August, driven primarily by failed pumps, algae-filled pools, and scaled or cracked surfaces.
The heat arrived early and persisted. Phoenix hit 100 degrees on March 18, the earliest such date in 20 years, and recorded a daily high of 114 degrees on August 25. Statewide, the summer averaged 2.7 degrees above normal temperatures.
What a Record Summer Does to a Pool
"Most homeowners think of a pool as something that sits there all summer. In reality, the pump, filter and water chemistry were working overtime for six straight months. By October, a lot of that equipment is worn out, and the damage usually doesn't show until something fails," said Santos Castro, owner of Optimal Pool Care.
Optimal Pool Care technicians report that this summer's damage falls into three categories:
- Overworked equipment. Pumps run extended hours to keep hot water circulating and clean. Motors overheat, bearings wear and seals fail, often simultaneously in early fall.
- Algae and unbalanced water. Sun and heat deplete chlorine faster than many homeowners can replenish it. A pool that goes without attention for a week or two can turn green within days.
- Surface and tile damage. Continuous evaporation deposits calcium from the Valley's hard water supply. That buildup creates scale on tile and plaster, while extreme temperature fluctuations crack coping and loosen tile.
Five Signs Your Pool Took Heat Damage
Optimal Pool Care recommends homeowners check for these warning signs this fall:
- The pump sounds different. Grinding, loud humming or a pump that trips the breaker typically indicates a worn motor or bearings.
- The water won't stay clear. Cloudy or green water that returns days after treatment points to a filter or circulation problem.
- A white crust at the waterline. Calcium scale on tile is easier and less costly to remove before it fully hardens.
- Rough, stained or flaking plaster. Surfaces that feel like sandpaper may require an acid wash or resurfacing.
- Cracked coping or loose tile. Small gaps allow water to penetrate behind the tile and develop into more extensive repairs.
Fall Is the Time to Fix It
Optimal Pool Care advises homeowners to have their pump, filter, water chemistry and surfaces inspected this fall, before minor heat damage escalates into a significant repair next summer. The company provides weekly pool cleaning and full repair service across Scottsdale, Phoenix, Paradise Valley, Fountain Hills, Cave Creek, Tempe, Mesa, Gilbert and Chandler, with written pricing provided upfront before any work begins.
"Weekly service is the best protection against a summer like this one. When someone checks your chemistry, cleans your filter and listens to your pump every week, small problems get fixed before they turn into a $1,000-plus pump replacement," Castro said.
