When to Close Your Pool in Burbank, CA: Deadline, Window & Checklist
Last updated: July 15, 2026 · Model window year: 2026 · dates · checklist · FAQ
In Burbank, the closing window runs from November 13 to November 23. Let the water cool out of the algae-growth range before covering — close too warm and you lift the cover onto a green surprise in spring — but finish ahead of the first freeze, which normals place around December 26. The live estimate below shows where Burbank's water sits today.
Burbank closing dates at a glance
| Closing window | November 13 – November 23 |
|---|---|
| Close by (deadline) | November 23 |
| First freeze, 50% probability | December 26 |
| Open by (recommended) | March 25 |
| Opening window | March 18 – April 8 |
| 61°F crossing (7-day mean) | April 8 |
| Swim-season length (80°F+ days) | 129 days |
| NOAA normals station | Burbank Valley Pump Plt · 1.4 mi · 655 ft |
A classic four-season pool calendar: open early into cold water, close late into cold water, and Burbank's 129 days of prime swimming sit safely in between.
Four water checkpoints anchor Burbank's year in the model: mid-April at about 61°F, mid-June at 68°F, mid-August near the 75°F peak zone, and mid-October easing through 69°F. The dates in the table are where those numbers cross the thresholds that matter.
The 12-step Burbank winterizing checklist
Sequenced against Burbank's November 13–November 23 window: chemistry while the pump still runs, blowouts before the equipment drains, cover last. Labels dictate every dose.
-
Balance the water a few days ahead
Do the chemistry midweek, close on the weekend: alkalinity and pH into label ranges with days of circulation left to spread them. Winter locks in whatever state the water holds on closing day.
-
Deep-clean the pool
Leave nothing organic behind: skim the surface, brush every wall and step, vacuum the floor slowly. What goes under the cover dirty comes out worse — winter only ever compounds what it's given.
-
Service the filter one last time
One final filter service per the manual — cartridges rinsed and stored dry indoors, sand or DE backwashed. Winter turns trapped gunk into concrete.
-
Apply winter chemicals per label
Run the winter kit through moving water: dose each product per its label with the pump on, give it a few hours to distribute, then start the shutdown. Chemistry added to still water stays where it lands.
-
Lower the water level
Take the level down only as far as the cover's manual says — usually just below the skimmer for solid covers, higher for many mesh systems. An empty pool is never the goal; shells crack and shift without water's weight.
-
Blow out the lines and plug returns
Work line by line: push air until the return spits dry mist, plug it against the flowing air, move on. Skimmer, returns, cleaner line, in whatever order your plumbing prefers — dry pipes are the entire point of closing.
-
Protect the skimmer
Give the skimmer something cheap to break: a guard bottle or rated plug absorbs the ice expansion that would otherwise split the housing.
-
Add pool antifreeze where blowouts fall short
Doubt is the criterion: any run you can't confirm dry gets pool-grade antifreeze at the label's per-foot rate. The automotive jug from the garage is for cars — it has no business in pool plumbing.
-
Drain the equipment
Open every drain plug on the pump, filter, heater, and chlorinator, and store the plugs in the pump basket so spring reassembly is a one-stop hunt. Move what you can indoors.
-
Set the air pillow and cover
Inflate the pillow to about two-thirds, center it, then bring the cover over and secure it per its design. Under ice, that soft dome is the difference between inward compression and outward wall pressure.
-
Remove and store ladders and rails
Pull ladders, rails, and the diving-board hardware; rinse, dry, and store them out of the weather. Anchor sockets get a dab of protectant so spring bolts turn freely.
-
Stage the cover pump
Solid covers need drainage all winter: set a cover pump or siphon before the first storm, not after. Standing water strains seams and invites a mid-winter emergency.
What to buy before the rush
The November crowd empties shelves in a predictable order. This is the short list worth owning before Burbank's window opens — nothing exotic, just the stuff everyone needs the same weekend.
-
Winter cover
The one purchase every other closing step depends on.
-
Cover pump
Standing water is a cover killer; this is the counter.
-
Expansion plugs + skimmer guard
The blowout's finishing move — one per return, one for the skimmer.
-
Pool antifreeze
Pool-rated glycol for the lines air couldn't clear.
-
Winter closing kit
Season-length winter chemicals in one label-dosed box.
-
Air pillow
A soft target for the ice sheet, centered under the cover.
How Burbank compares locally
Burbank closes in the earlier half of California's calendar. Neighbors run close: Glendale (4 mi away) models its deadline at November 23 (the same day vs Burbank's November 23), while Los Angeles (7 mi) shows December 8. The spring mirror of this page is the Burbank opening guide, and the season overview draws both windows on a single bar.
Every number on this page traces to one instrument cluster: Burbank Valley Pump Plt, 1.4 miles west of Burbank's center at an elevation near 655 feet. NOAA computed its 1991–2020 normals from roughly three decades of daily readings — long enough that one strange spring in Los Angeles County barely moves the dates.
Field notes for Burbank owners
Cover pumps die in the cold — plan for it
A cover pump left running into a hard freeze can lock in ice and burn out. On freezing forecasts, pull it, let the storm pass, and put it back for the melt. Automatic models with freeze protection earn their price in exactly one forgotten weekend.
Salt cells overwinter indoors
Remove the cell at closing, inspect and clean per the manufacturer, and store it inside with the unions capped. A dummy cell or spacer keeps the plumbing sealed. Cells left in outdoor plumbing through freezes are a common — and completely avoidable — spring casualty.
Leaf season vs closing day
If your yard drops serious leaves, the cheap trick is a leaf net over the main cover through the drop, then one bulk removal before snow. Leaves that winter on (or worse, under) the cover steep like tea and hand you stained water and clogged pumps in spring.
Burbank pool closing FAQ
What temperature should water be to close a pool?
Cold enough that biology has clocked out — below 65°F and falling, ideally low 60s. The widget above tracks Burbank's actual water; the normals say the durable cool-down arrives near November 13, and anything inside the window to November 23 closes clean.
Can you close a pool too early?
Absolutely. A pool closed warm is an algae incubator: no circulation, fading sanitizer, and weeks of growth-friendly temperatures. Burbank's water doesn't settle below the risk zone until around November 13 — closing much before that trades a few weekends of maintenance for a rough spring.
Do I need antifreeze in pool lines?
Treat antifreeze as a backup, not a substitute: the real protection is air in dry lines. Where a full blowout isn't possible, pool-grade antifreeze per label is cheap insurance against a cracked pipe — worth it anywhere freezes are routine, and Burbank sees them from about December 26.
How far should I drain my pool for winter?
Only to the line your cover manufacturer prints — a few inches below the skimmer for most solid covers, close to operating level for many mesh designs with the skimmer plugged. The water you leave in is structural: it holds the shell against groundwater all winter.
What happens if you don't winterize a pool?
Expect equipment damage first — cracked pump volutes, split filter tanks, ruptured heater exchangers — then plumbing leaks that surface at startup. In Burbank, normals put the first freeze near December 26; everything after that date is borrowed time for an unwinterized system.
When is the last safe date to close in Burbank?
Our model's practical deadline is November 23 — set by the cool-down plus ten days (the freeze normal, December 26, leaves room to spare). Push much past it and you're winterizing in freeze-warning weather, rushing the blowout, and hoping the cover goes on before the first hard night. Inside the November 13–November 23 window, none of that drama applies.
