At 21 degrees Celsius or 69.8 degrees Fahrenheit, the water is getting too cold for wintertime swimming. For most people that is. I wouldn't recommend these temps in the summer unless you're someone who prefers chilly waters or ice swimming.
The Canadian-based group considers cold temperatures to be under 10°C, while cool is 10°C to 20°C, warm or hot is 21°C to 39°C and anything above 40°C is considered scalding. It's safe to say you don't want to swim in waters less than 10°C or anything exceeding 40°C.
70F (21C) Water feels quite cold to most people.
20C: You might like a wetsuit for longer swims but not necessary. 18C: Time for a wetsuit unless your swim time is quite short. Water under 70℉ (21℃) is considered cold and can cause you to have a harder time breathing.
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.
For most residential pools, a comfortable swim temperature range will be between 26-30 degrees.
For all around use, Australian swimming pool temperatures are best around 26 degrees Celsius to 28 degrees Celsius. 26 degrees if you're planning on some brisk swimming and the less activity you plan to do, the closer to 28 you should set the pool's temperature to.
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.
Mid 20s degrees: warm enough for everyone.
And being so close to the commonly approved ideal climate, temperatures of 20 degrees will make you feel comfortable. Ideal fabrics during this period will be cotton, satin, acrylic, denim, faux leather, suede, and lightweight polyester fleece.
At 20°C, water would be in its liquid state. It is the normal boiling point of water.
1 Answer. Below 20 is cool, below 10 degrees is cold, and below zero degrees means that it will be icy outside as the water will freeze and it will feel very cold outside.
Is 30 degrees a cold wash? No, a 30ºC wash is generally considered a warm wash. A cold wash is below 20°C and is usually reserved for clothes that are very delicate. Washing at 40ºC is also considered a warm wash, while 60ºC is a hot wash and 90ºC is a very hot wash.
Depends on what you like, but 21 would be fine for my family and me. A whole day in full on sun is a bit overwhelming( and I'm an olive skinned sun lover), so 21 with a little cloud can be a great beach day . At 21 degrees, we'd go early and leave by 10, or leave it till after 6!
The ideal indoor temperature ranges between 20 to 21 degrees Celsius, in the nursery and bathroom you should keep the maximum heat at 23 degrees.
However, most experts agree that a temperature between 24 and 32 degrees is ideal for most people. This range will allow swimmers to stay in the water for long periods without getting too cold or hot.
Water Temperature of the Sea Below 22°C (72°F)
For swimming this is considered fairly warm and should be enjoyed by most, though some people may still find it a little too cool for their liking.
Some studies showed solid evidence that cold-water swimmers often experience significant improvements in overall cardiovascular health. Cold-water immersion triggers a “shock response” that stresses the cardiovascular system and elevates the heart rate – a chief goal of high-intensity heart-healthy exercise.
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.
Keep Swimmers Comfortable
Set your pool heater's thermostat to a temperature between 78°F and 82°F (26°C and 28°C) to keep the majority of swimmers comfortable. Maybe a little cooler if you're in an area with very hot summers, or a little warmer if you live in a milder climate.
Pool water temperatures typically run between 78 and 82 degrees. Any cooler than 78 and you may come out of the pool shivering. Any warmer than 82 and you may feel like you're taking a bath.
22C is pleasantly mild, definitely not cold. It is roughly equivalent to what the Americans call 70F. In other words, a nice day.
25C water feels like “slightly warm room temperature”, because normal room temperature is taken to be 20C – 25C. If you get into water exactly the same temperature as your skin, will you feel it? Yes, it will feel uncomfortably warm.
20-22 is too cold. Also consider the evening temperature. A daytime max of 22 degrees would probably drop to 15 degrees in the evening, too cold to sit outside in light clothing.
