The Quiet Season: Winter Pool Care in the Valley and Westside
by Spectrum Pool Care
Winter here is gentle. The water cools, the pool slows down, and the spa has its moment. Here’s what changes in the cooler months, and how to make the most of the quiet season.
From December through February, an unheated pool in the Valley or on the Westside usually settles into the high 50s to low 60s. Days are shorter, the sun sits lower, and the water simply asks for less. Algae grows slowly in cool water, chlorine lasts longer, and the pool takes on a calm, glassy stillness that many owners come to love.
It’s also the season of the spa. A warm soak on a cool evening is one of the real pleasures of a Southern California backyard, and the heater gets its busiest months of the year.
Through the Cooler Months
What a Winter Pool Asks For
Shorter run times
Cooler water needs fewer hours of filtering each day. Trimming the pump schedule saves energy while still turning the water over.
Freeze protection
On the occasional cold night, a small sensor switches the pump on when the air nears freezing, keeping water moving through the pipes.
Rain
Most of our rain falls between December and March. It can raise the water level, bring in debris and nudge pH and alkalinity a little lower.
Spa season
A spa is a small body of warm water, so its chemistry shifts faster with use. A little attention after busy evenings keeps it inviting.
Lighter chemistry
Chlorine demand drops in cool water, so levels are kept steady with smaller additions. Balance still matters all winter.
Late leaves
Sycamores and other deciduous trees drop the last of their leaves now, so baskets still fill, even when the pool is resting. Wind and rain bring in more at once.
Between Visits
A Few Ways You Can Help
Weekly service means we’re at your pool once a week, and winter weather doesn’t always keep to that schedule. A few small habits between visits keep the water moving and clear until we’re back.
Empty the skimmer baskets
After a windy day or a storm, a quick look in the skimmer baskets makes a real difference. Full baskets slow the flow of water to the pump and filter, so emptying them between visits keeps circulation strong.
Trim back trees and plants
Leaves do more than float. As they settle and break down, they slow the water’s flow and use up chlorine. Trimming branches and shrubs back from the pool lightens that load all year.
Keep the water at mid-skimmer
The skimmer works best when the water sits about halfway up its opening. Rain can raise it, and dry weeks can lower it, so a glance now and then helps.
Give it time after a big storm
A heavy storm can bring in more debris than one visit can clear. A pool may take a visit or two to fully catch up, and emptied baskets in between help it get there sooner.
Prefer to leave it to us? For pools under heavy trees, or owners who would rather not check baskets between visits, we offer twice-weekly service through the off season as an added option. A second visit each week keeps baskets clear, water moving and chlorine steady through the windy and rainy months. Just ask when you call.
Looking Ahead
A Good Season for Projects
Because the pool is used less, winter is a natural time for the work that would interrupt a summer of swimming. It’s a calm window to plan ahead, and the pool is ready the first warm weekend of spring.
A variable-speed pump for quieter, more efficient circulation all year.
A filter cleaning or new cartridges, so spring starts with a fresh filter.
A heater check while the spa is in regular use.
LED pool and spa lights, enjoyed most on long winter evenings.
Automation, so the spa can be warming before you get home.
From our routes: weekly service carries on through winter. We adjust the water chemistry for the cooler months and keep the pool clean, so it’s ready the moment spring arrives. If your equipment isn’t running as expected, just let us know.
