Greater New York has seen intense cold and snow this past winter. Sub-freezing daily highs were the norm, and the infamous February blizzard needs no further introduction.
Fortunately, warmer days are coming. If you own a pool, you have surely thought about pulling back that tarp and getting your first exposure to summer. The ideal opening, however, needs to strike a proper balance. Open too early, and you’re paying chemical bills on an ice bath. Open too late, and the water turns green with algae.
A proper opening avoids both issues and helps you get the summer spirit in motion. Below are some tips for pool openings in the Northeast, from figuring out the ideal weather conditions to preparing for opening day.
The Importance of Proper Timing
The labor, costs, and unreliable spring weather mean many Northeast-based pool powers wait too long to open their pools. Waiting too long to open a pool can result in unfavorable consequences, such as:
- Algae growth
- Imbalances in water chemistry
- Clogged pump/filtration systems
A general rule of thumb for timing is to open your pool once daily high temperatures stay consistently above 50°F. While it may not necessarily be swimming weather yet, having the proper filtration/chlorine systems running will prevent algae growth.
In much of the Northeast United States, temperatures generally reach this level during April, but sometimes in late March or early May as well. Consistency is also important; heat waves and cold snaps do happen, but what’s important is that the average day reaches the ideal mark.
Other Important Factors
here are a number of other factors, beyond weather and calendar dates, that you should consider when opening day arrives. These include:
- Whether or not your pool is heated
- Shade coverage
- Accumulated debris on the pool cover
- Geography
If your swimming pool is heated, you can likely open your pool and go swimming earlier in the season. The temperature variation in the Northeast makes it an excellent region to own a heater.
In areas with a significant tree canopy such as Northern Westchester County, leaf litter accumulation on pool covers can promote algae growth. If natural debris is a significant problem on your property, an earlier pool opening is advisable.
More shaded pools can also lead to slightly cooler temperatures, further impacting opening times.
Even within the Greater New York area, temperatures can vary between areas. The highland areas of Orange County and Northern New Jersey are typically a few degrees colder due to higher elevation, while denser suburbs closer to the city see warmer temperatures due to the infrastructure absorbing more heat.
How to Prepare for Pool Opening Day
Even if the temperatures aren’t ideal for a proper pool opening day, you can take steps to ensure a smooth process even before it arrives:
- Keep your pool cover free of debris. This prevents the growth of unwanted algae and avoids a frustrating cleanup process.
- Inspect your tarp periodically. Make sure it fits tightly and no tears are present.
- If possible, trim trees or shrub branches. Keeping them under control prevents accumulation of more debris. Greater sun exposure also means faster water temperature progression.
- Examine your equipment to ensure there are no leaks, cracks, or other signs of damage.
What To Do About Early/Late Openings
Openings are not always perfect, and you may end up choosing a date too late or early. This is a common mistake for new pool owners, who have yet to develop an intuitive understanding of the seasons. If you find yourself in either of these dilemmas, don’t stress.
Opening Too Early
Perhaps you are eager for your first swim and decide to open early. Though earlier starts can help prevent algae, keep in mind that water temperature is unlikely to be very pleasant for a swim. Electrical and chemical bills will go up, not a great mix when the water is still too cold.
Like leaves in the fall, spring flowering can increase natural plant debris around this time. Heavier spring rains can also bring higher or overflowing water levels. This can also overstrain your filters.
If you open your pool too early and don’t have a heater, be sure to keep your pool free of natural litter that can promote algae and pollen growth. You will also need to monitor pH levels closely, as you will gradually need more chemicals as outdoor temperatures gradually rise.
Opening Too Late
A frequent reason for delayed pool openings is lack of time. Under such circumstances, it can be easy to neglect your pool tarp and equipment. Be sure to inspect your pool cover if you are opening late and haven’t checked in for a while.
Algae and pollen accumulation are common consequences of late openings. Not only does algae make your pool unfit to swim in, but it also clogs your filtration system. If algae is a problem, use algaecide following cover removal to clear it out and prevent further spread.
Though a chemical shock is an important part of any opening, a large one is especially recommended for later starts, as the chlorine will do significant damage to algae and kickstart pool sanitization.
