When to Close Your Pool in Conway, AR: Deadline, Window & Checklist
Last updated: July 15, 2026 · Model window year: 2026 · dates · checklist · FAQ
Target October 26 as the practical closing deadline in Conway. Our model of NOAA 1991–2020 normals keeps the 7-day mean above 61°F until October 16; after that, cooling water winds algae down while you work the checklist below. The hard stop is equipment freeze damage — normals put Conway's first 32°F night near November 2.
Conway closing dates at a glance
| Closing window | October 16 – October 26 |
|---|---|
| Close by (deadline) | October 26 |
| First freeze, 50% probability | November 2 |
| Open by (recommended) | April 7 |
| Opening window | March 31 – April 21 |
| 61°F crossing (7-day mean) | April 21 |
| Swim-season length (80°F+ days) | 135 days |
| NOAA normals station | Conway · 2.3 mi · 312 ft |
Conway's 135-day warm season leaves comfortable margins on both ends — the windows above aim you at the cheap-chemistry versions of each transition.
Put dates aside and follow the water: the Conway curve says roughly 58°F by mid-April, 76°F by mid-June, 81°F in mid-August, then back down through 64°F in mid-October. The summer ceiling sits near 81°F, and every window above is just a line drawn on this curve.
The 12-step Conway winterizing checklist
A closing is a plumbing project with a chemistry warm-up. Start a few days ahead of your target date, keep every dose per its product label, and don't skip the photographs — spring-you reassembles from them.
-
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
Make the last cleaning the best one of the year: full skim, full brush, careful vacuum. Debris left behind steeps all winter and greets you as April's water problem.
-
Service the filter one last time
Clean media goes into storage, dirty media comes out worse: backwash the sand or DE, rinse the cartridges, all per the manual, before anything drains.
-
Apply winter chemicals per label
Winter chemicals go in before shutdown, not after: label-dosed, circulated for a few hours, distributed evenly. A floater dropped on still water protects one corner.
-
Lower the water level
Your cover's manual sets the number — commonly a few inches under the skimmer for solid covers, barely below normal for mesh. Stop there. The remaining water isn't laziness; it's ballast holding the shell in the ground.
-
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
The skimmer throat is where trapped water has no escape — park a guard bottle or rated plug in it and let ice crush the cheap part.
-
Add pool antifreeze where blowouts fall short
Antifreeze is the insurance policy for doubtful lines, not a replacement for the blowout: pool-grade product, label dosing, and only where air couldn't finish the job.
-
Drain the equipment
Every vessel on the pad — pump, filter, heater, chlorinator — gets its drain plugs pulled. Drop all the plugs in the pump basket; that's the one place everyone looks first in spring.
-
Set the air pillow and cover
Float a centered air pillow, then land the cover and secure it the way its design intends — bags, cable, or straps. Ice sheets need somewhere to collapse inward, and the pillow is that somewhere.
-
Winterize the water features
Waterfalls, slides, and spillover spas hold water in places gravity won't clear — blow those lines separately and plug them, or they'll be the one crack you find in spring.
-
Calendar the off-season checks
Set a monthly reminder from October 26 to spring: check cover tension, pump off standing water, and glance at the water level. Fifteen minutes a month protects the whole closing job.
What to buy before the rush
The October crowd empties shelves in a predictable order. This is the short list worth owning before Conway's window opens — nothing exotic, just the stuff everyone needs the same weekend.
-
Winter closing kit
Season-length winter chemicals in one label-dosed box.
-
Air pillow
Centers under the cover so ice pushes inward, not outward.
-
Winter cover
Sized to overlap; the cheapest insurance the pool wears all winter.
-
Cover pump
Standing water is a cover killer; this is the counter.
-
Expansion plugs + skimmer guard
Seals blown-out lines and sacrifices itself to skimmer ice.
-
Pool antifreeze
Pool-rated glycol for the lines air couldn't clear.
How Conway compares locally
Conway closes in the earlier half of Arkansas's calendar. Neighbors run close: Little Rock (25 mi away) models its deadline at October 29 (3 days later vs Conway's October 26), while Fort Smith (109 mi) shows October 30. The spring mirror of this page is the Conway opening guide, and the season overview draws both windows on a single bar.
The measuring stick here is Conway — 2.3 miles to the northwest, elevation about 312 feet. Its 1991–2020 record is what the model reads for Conway; your backyard in Faulkner County will run a touch warmer or cooler with shade, wind, and pavement, which is exactly the slack the two-week lead absorbs.
Field notes for Conway owners
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.
Blowout first, antifreeze second
Air is the only guaranteed freeze protection: a line that's verifiably dry cannot burst. Antifreeze (pool-grade, per label) is the fallback for lines you can't confirm — long runs, low spots, water-feature plumbing. Doing antifreeze instead of a blowout, rather than in addition, is how most cracked returns happen.
The skimmer is the most breakable part you own
Skimmer bodies crack because water freezes inside the throat with nowhere to push. A sacrificial bottle or spring-loaded guard absorbs that expansion for a few dollars. It's the highest-return item in the entire closing kit relative to what it protects.
Conway pool closing FAQ
What temperature should water be to close a pool?
Close once water holds below about 65°F — the point where algae go mostly dormant — and before hard freezes. In Conway, the 7-day mean drops through the threshold around October 16, so the window between then and October 26 is the sweet spot for a clean, stable close.
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. Conway's water doesn't settle below the risk zone until around October 16 — closing much before that trades a few weekends of maintenance for a rough spring.
Do I need antifreeze in pool lines?
Only where water might remain. If every line is properly blown out and plugged, air is the antifreeze. Lines you can't verify dry — long runs, low spots, water features — get pool-grade antifreeze dosed per its label. With Conway's first freeze normal near November 2, don't leave that question open.
How far should I drain my pool for winter?
Follow the cover's instructions first: solid covers usually want water a few inches below the skimmer; some mesh setups run higher with the skimmer sealed. The hard rule is never empty — hydrostatic pressure can lift or crack an empty pool, a far worse outcome than any freeze.
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 Conway, normals put the first freeze near November 2; everything after that date is borrowed time for an unwinterized system.
When is the last safe date to close in Conway?
October 26, by our model — a week of margin before the November 2 first-freeze normal. Later closes happen, but they happen in gloves. The winterizing steps above take a weekend; leave yourself at least that much runway before Conway's first freeze-risk stretch.
