Many swimmers ask, is 79 degrees hot enough to swim when planning a pool or open water session? This temperature sits near the common comfort zone for recreational swimming, but personal comfort depends on several factors.
Air temperature alone does not dictate how the water feels, so understanding heat, humidity, and activity level is essential for planning a safe and enjoyable swim.
| Water Temperature | Typical Feel | Recommended Activity | Notes for Comfort |
|---|---|---|---|
| 70–77°F (21–25°C) | Cool to mild | Short drills, splash play, acclimation | May feel cool initially; wetsuits help in open water |
| 78–82°F (26–28°C) | Neutral to pleasantly warm | Lap swimming, lessons, casual recreation | Often comfortable for most swimmers without a wetsuit |
| 83–86°F (28–30°C) | Warm | Leisure swimming, therapy, warm water workouts | May feel too warm for intense training sessions |
| Below 70°F (21°C) | Cold | Acclimation only, very short exposure | Risk of shock and rapid fatigue; wetsuit strongly recommended |
Is 79 Degrees Warm Enough For Comfortable Swimming
At 79°F, many recreational swimmers find the water warm enough for extended sessions, especially in calm environments. This range supports relaxed laps and skill practice without overheating quickly.
Competitive athletes may still use this temperature for recovery workouts, while families often prefer it for casual play and water aerobics.
How Air Temperature And Humidity Affect Perceived Warmth
The Role Of Air Temperature
On a sunny day near 79°F, air can heat the pool deck and immediate water surface, making entry feel less shocking. On a breezy or cooler day, the same water may feel cooler than the thermometer suggests.
Higher humidity reduces evaporative cooling on your skin after you exit, while strong wind can intensify the chill quickly, especially for children and older swimmers.
Activity Type And Duration Impact Comfort
Leisure Versus Training
Light leisure swimming feels comfortable at 79°F, but high-intensity interval training can raise internal heat and make the environment feel warmer over time.
Open Water Considerations
In lakes or oceans, factors like depth, currents, and local climate can shift perceived warmth, even if the measured temperature matches a pool reading at 79°F.
Physiology And Personal Factors
Body Composition And Fitness
Individuals with higher body fat may retain warmth longer, while very lean swimmers might cool down faster. Fitness level and circulation also influence how long you can comfortably swim at 79°F.
Age And Health Conditions
Children lose heat rapidly and may prefer warmer water, while older adults might seek slightly warmer settings to keep muscles relaxed. Medical conditions and medications affecting circulation can change comfort at this temperature.
Optimal Conditions For Recreational Pool Swimming
To maximize enjoyment and safety at this temperature, align timing, attire, and activity type with your comfort level.
- Choose midday or early afternoon when air and surface water are warmest.
- Enter gradually and move slowly for the first few minutes to allow acclimation.
- Use a light rash guard or swim shirt if you are sensitive to cooler water.
- Plan shorter intervals for young swimmers and warm up between sets.
- Monitor how you feel after exiting and adjust session length accordingly.
FAQ
Reader questions
Is 79 degrees too cold for a child learning to swim?
Most children do well in the high seventies, but some may prefer the mid eighties for longer lessons and reduced shivering.
Can I swim laps at 79 degrees without getting chilled?
Yes, if you warm up gradually, limit lap time, and dry off between sets, many people find 79°F suitable for continuous swimming.
Should I wear a wetsuit at 79 degrees in open water?
It depends on your tolerance and local climate; in cooler regions or during longer swims, a light wetsuit can help maintain core temperature.
Does 79 degrees feel different in a saltwater pool versus a chlorinated pool?
Saltwater often feels slightly warmer at the same temperature, and many swimmers report greater comfort in saltwater environments around 79°F.
