Is 60 degrees too cold to swim?
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.
77 Degrees - 70 Degrees
While it's not as immediately comfortable to swim in as something above 77 degrees, this is certainly by no means uncomfortable or dangerous. However, your breathing can be negatively affected by this temperature, though not enough to be harmful.
Generally speaking, anytime the water temp is below 70 degrees, a wetsuit can feel pretty good. And anytime the water temp is below 65, a wetsuit might actually be advised in order to keep the swimmer from having a reaction to the cold.
Since it is important to get out of the water as fast as possible, sometimes swimming can be effective if the water is not around the freezing point. In water that is 32-40 degrees Fahrenheit, a person can typically swim for up to 7 minutes before exhaustion.
17-20 DEGREES: Summer swimming
Still fresh on entry, but comfortable picnic lazy-hazy summer swimming.
Just because the water is 65 degrees doesn't mean it's safe to swim in. People should treat any water temperature below 70 degrees with caution, even if they're not wearing a wetsuit or drysuit. It becomes progressively more difficult to control your breathing at 60-70 degrees Celsius waters.
Cold shock can be just as severe and dangerous from water temperatures of 50-60F (10-15C) as it is from water at 35F (2C). Gasping for a breath or rapid breathing from sudden immersion can be triggered by water as warm as 77F (25C).
At a water temperature of 40 to 50 degrees, death may occur in 1 - 3 hours. At a water temperature of 50 - 60 degrees, death may occur in 1 - 6 hours. At a water temperature of 60 - 70 degrees, death may occur in 2 - 40 hours.
It develops much more quickly than standard hypothermia because water conducts heat away from the body 25 times faster than air. Typically people in temperate climates don't consider themselves at risk from hypothermia in the water, but hypothermia can occur in any water temperature below 70°F.
Don't Swim if Your Pool Water Is Below 70 Degrees
According to the National Center for Cold Water Safety, water temperatures below 70 degrees Fahrenheit should be treated with caution. The “perfect” temperature for a swimming pool tends to range between 77 and 82 degrees. The average is somewhere around 79 degrees.
How fast can you get hypothermia in 70 degree water?
In water temperatures from 70-80 degrees, exhaustion or unconsciousness can set in within 3-12 hours; 60-70 degrees, 2-7 hours, and in water from 50-60 degrees, you could be unconscious in 1-2 hours.
What pool temperature is too cold? Extremely cold water — 50 degrees or below — can lead to cold shock. This occurs when the body is overwhelmed by extreme cold, and it can lead to a heart attack or unconsciousness, which can lead to drowning.
Initial immersion in cold water should be done in a gradual way so the airway is kept above the water. You do see lots of open water swimmers diving in, but they've probably spent many years getting used to the cold, so their cold shock response is much less severe than someone who has never done it before.
- Wear a wetsuit or drysuit while in the water.
- If you do not have a wetsuit or drysuit, only go waist deep.
- If you want to fully submerge your body in the water, only stay in for a limited amount of time.
- Be cautious of drinking booze before you get in the water.
50-50-50 Rule
A person has 5 minutes to swim 50 yards in 50°F (10°C) water and has 50/50 chance of surviving the attempt.
The temperature of the water was -2.2 degrees Celsius when Titanic was sinking.
In the air, hypothermia can develop in as little as five minutes in temperatures of minus -50°F/-45.5°C in people who are not dressed properly and have exposed skin. At -30°F/-34.4°C, hypothermia can occur in about 10 minutes. Death can occur in under an hour in extremely cold conditions.
It's important to note that the study report did not recommend this rule. However, the research concluded that: “For lean, elite level swimmers, 16°C and 18°C will cause hypothermia in under two hours. For a shorter swim, 16°C is possible.
15 to 25 degrees is around the temperature that most swimmers find comfortable with initially feeling cold once they have entered the water and then being able to swim for several hours at a time at no risk.
Thirty degrees and above is considered too warm for comfortable swimming by virtually all swimmers. Triathletes use a standard measurement of 24 degrees Celsius / 75 degrees Fahrenheit as the temperature up to which they are allowed to wear wet-suits. By that standard, 24 degrees is the upper limit of cold water.
Can you swim in 64 degrees?
No matter where you're swimming, avoiding water below 70 degrees Fahrenheit is a good rule of thumb for the average swimmer. The truth of the matter, though, is that 70 degrees is still pretty chilly. You'll probably have a better time if you wait for warmer water. In fact, you'll be safer, too.
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.
Is 64 degrees too cold to swim? Don't swim in water below 70 degrees Fahrenheit.
What is Cold Water Shock. Cold water shock (CWS) is an involuntary response by the body being suddenly or unexpectedly immersed into water which has a temperature of less than 15 °C. Your body's reaction to CWS will affect your capability to move and may seriously affect your breathing and heart.
In most of the world – anywhere where water is cooler than body temperature – swimmers can achieve hypothermia at any time of year, it's just a matter of how long it will take.
That's why it is not recommended to swim for help, but remain with the boat or something else that floats while keeping your head above water while awaiting rescue. Hypothermia - True hypothermia sets in after about 30 minutes.
Shivering. Exhaustion or feeling very tired. Confusion. Fumbling hands.
And while the weather has been unusually warm thus far in much of the country, temperatures need not be at freezing, or even very low, for hypothermia to occur. Most cases occur in air temperatures of 30 to 50 degrees. But people can succumb to overexposure even at 60 or 70 degrees.
Safe temperatures for swimming pools vary with type of activity. According to the World Health Organization, water temperatures ranging from 78 to 86 degrees Fahrenheit are generally comfortable and safe for those engaging in moderate physical activity in a pool.
If you're looking for a perfect pool temperature, not too hot, not too cold, 77 – 82 degrees (25 – 28°C) may be the way to go according to most recreational swimmers. In most cases, pools should be comfortable, and the average swimmer will agree with this.
Is it OK to swim in cold weather?
There is a significant difference between how air temperature and water temperature affect the core temperature of the body-body heat is lost much faster in the water. According to the National Center for Cold Water Safety, caution should be taken in any water less than 70 degrees.
Water temperatures are slow to heat up, and just as slow to cool down. Water is very "stubborn" to change temperature. It takes 4 times the energy to heat up water than to heat air. Water also "feels" colder because water is a more efficent medium than air to cool our body down.
Typically people in temperate climates don't consider themselves at risk from hypothermia in the water, but hypothermia can occur in any water temperature below 70°F.
In water temperatures from 70-80 degrees, exhaustion or unconsciousness can set in within 3-12 hours; 60-70 degrees, 2-7 hours, and in water from 50-60 degrees, you could be unconscious in 1-2 hours.

| Water Temperature | Exhaustion or Unconsciousness in | Expected Survival Time |
|---|---|---|
| 70–80° F (21–27° C) | 3–12 hours | 3 hours – indefinitely |
| 60–70° F (16–21° C) | 2–7 hours | 2–40 hours |
| 50–60° F (10–16° C) | 1–2 hours | 1–6 hours |
| 40–50° F (4–10° C) | 30–60 minutes | 1–3 hours |
Are my cold-water swims okay for my heart? A. Swimming is an excellent exercise for the heart, arteries, lungs, and muscles. If you enjoy swimming in cold water and have been doing it for some time with no ill effects, it's probably fine for you.
