As I previously mentioned in my list of pool care essentials, having a thermometer to track your pool temperature is important because algae loves to grow in hotter temperatures––generally 85 degrees or above.
Additionally, Is 75 degree water too cold for swimming? According to the National Oceanographic Data Center, 70-78 degrees is where most people feel comfortable swimming. I have found that a water temperature of 70-78 degrees is a bit cold for most of us north Texans.
Does heating your pool cause algae? If you have a pool heater, you should turn it off. Warmth helps produce an environment in which algae can grow. You should check your pump and your pool filter. Once they are in top condition, you should run the pump until the pool is clear again.
Subsequently, What temp does algae stop growing? Algae growth is stopped at temperatures below 40° F, but some algae can continue to survive, and like weeds in a lawn, can go dormant over the winter, coming back to life in early spring, weeks before you open the pool.
FAQ
Does covering a pool prevent algae?
Cover Your Pool
Not only is a pool cover a barrier to algae entering the pool, it’s also a barrier to leaves, bugs, bacteria, and dirt from entering the pool, decomposing, and providing the nourishment that helps algae to thrive.
Is swimming in 65 degree water safe? When water temperatures are between 60 and 70 degrees it becomes progressively more difficult to control your breathing. It becomes very dangerous in water temperatures between 50 and 60 degrees. You lose the ability to control breathing in this temperature range, according to the National Center for Cold Water Safety.
How cold is too cold to swim in a pool? For safety’s sake, most swimmers should wait until the water temperature reaches at least 70 degrees Fahrenheit. But even that can be too chilly for most people to enjoy the experience. If you give the water time to warm up, you’ll stay safer and have more fun.
What’s the coldest water you can swim in? Baltic: This is the coldest water temperature rating and falls between 0-6 degrees. This range of cold water is considered too cold to swim in and can feel as though you have been submerged in ice.
How do I keep my pool algae free?
How to Prevent Algae in Pools
- Good water balance; pH 7.2, Alk 100 ppm, Cal 200 ppm, Cya 30-50.
- Good water filtration; two turnovers per day, 16-18 hours total run time.
- Good water circulation; brushing, eyeball fittings, pool cleaners can help.
- Good water sanitation; keep consistent daily chlorine levels of 2-4 ppm.
Can you swim in a pool with algae bloom? Algae can be very slippery, causing swimmers to fall resulting in bumps, bruises, cuts and even broken bones.

Besides causing injuries, an algae infested pool creates a higher risk of drowning for those who are not expert swimmers or those who fall unconscious.
Why does my pool turn green in August?
But you have to understand that algae spores constantly enter the pool, because of weather factors such as rain, wind, and sometimes items like contaminated pool cleaning products. It’s important to maintain good circulation, filtration, and sanitation or else pool algae may form.
Why is my pool green with high chlorine? When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there’s not enough. But be careful—adding too much chlorine in pool water can cause those metals to oxidize and turn the pool a different shade of green.
When should I open my pool to avoid algae?
A late September or October closing is a great way to set up for success in the spring. If you are already suffering from an algae bloom; take care of that before you close. Opening your pool early in the spring is a good idea if you want clear water.

Should I cover my pool every night? You should cover your pool every night for several reasons. First off, a pool cover saves energy and conserves water by decreasing the amount of make-up water. Also, it reduces the consumption of chemicals, and finally, it saves a lot of cleaning time since it keeps the debris out of the pool.
Should I leave the pool cover on in winter?
Leaving your solar blanket on the pool over winter will allow you keep leaves and other organic material out of the pool. Which means less cleaning for you and also less food for algae or other bugs. What is this? The other benefit of keeping the blanket in place is it will help to minimize chemical evaporation.
Can you swim in 68 degree water? You can swim in 68 degrees and you should be fine. I did a race last spring where the water was 58, and there were a few guys who did it without wetsuits. You’d be better off if you got yourself into a wetsuit, but I wouldn’t rule the race out for that reason alone.
How long can you survive in 55 degree water?
Expected Survival Time in Cold Water
| Water Temperature | Exhaustion or Unconsciousness in | Expected Survival Time |
|---|---|---|
| 50–60° F (10–16° C) | 1–2 hours | 1–6 hours |
| 40–50° F (4–10° C) | 30–60 minutes | 1–3 hours |
| 32.5–40° F (0–4° C) | 15–30 minutes | 30–90 minutes |
| <32° F (<0° C) | Under 15 minutes | Under 15–45 minutes |
How long can you swim in 60 degree water? The average person can swim for about 30 minutes in water at 60 degrees, but this time may vary depending on your size and swimming style. Those who have more body fat are able to last longer because they produce more heat than those with less weight.
