How to Extend Your Pool Season in Sullivan County (Start Swimming in May!)

If you own a pool in Monticello or anywhere in the Hudson Valley, NY, you already know the frustration—just when your pool is perfect, summer starts to wind down. But what if you could open earlier, swim longer, and get more value out of your investment?

At Wechsler Pool & Supply, homeowners are discovering smart, cost-effective ways to extend their pool season from early May through late September (or even October).

This guide breaks down exactly how to do it.

️ 1. Install a Pool Heater (The Game-Changer)

If you want to start swimming in May, a heater isn’t optional—it’s essential in the Catskills climate.

Your main options:

• Gas heaters – Fast heating, ideal for quick warm-ups in spring
• Heat pumps – Energy-efficient for maintaining temperature all season

Why it matters in Sullivan County:

• Spring nights are still cold (often below 50°F)
• Without heat, your pool may not reach comfortable temps until late June

Pro tip: A properly sized heater can bring your pool to 78–82°F weeks earlier.

☀️ 2. Use a Solar Cover (Low-Cost, High Impact)

A solar cover is one of the most affordable ways to extend your pool season.

Benefits:

• Retains heat overnight
• Reduces evaporation by up to 95%
• Works alongside heaters to cut energy costs

In the Hudson Valley, where nights cool quickly—even in June—this simple upgrade can add weeks to your swim season.

3. Keep Water Balanced (It Heats Faster)

When your water chemistry is off, your pool:

• Loses efficiency
• Feels colder
• Becomes uncomfortable to swim in

Ideal targets:

• pH: 7.2–7.6
• Proper sanitizer levels
• Clean filtration system

Routine maintenance from a local expert like Wechsler Pool & Supply ensures your pool is always ready—even in shoulder seasons.

4. Open Early (But Open Smart)

Many homeowners wait until June—but that’s a mistake.

Why opening in May works:

• Prevents algae growth
• Easier cleanup
• Gets your system running sooner

Pair an early opening with a heater + cover, and you can realistically swim by mid-May.

️ 5. Add Wind Protection & Landscaping

Wind is a hidden factor that cools your pool quickly.

Solutions:

• Privacy fencing
• Hedges or shrubs
• Strategic landscaping

Reducing wind exposure helps your pool retain heat longer, especially in elevated or rural areas common across Sullivan County.

Is Extending Your Pool Season Worth It?

Absolutely.

By combining:

• A heater
• A solar or automatic cover
• Early opening service

You can add 6–10+ extra weeks of swimming per year.

That’s not just comfort—it’s maximizing your investment.
