How Warm Does It Have to Be Outside for Non Heated Pool Water to Be Above 18 Degrees Celsius?

The temperature of non-heated pool water depends on several factors, including the ambient air temperature, humidity, wind speed, and solar radiation. Generally, the air temperature needs to be consistently above 18 degrees Celsius for several days for the pool water to reach this temperature.

Factors Affecting Pool Water Temperature:

  • Ambient Air Temperature: The primary factor affecting pool water temperature is the surrounding air temperature. Warmer air will transfer heat to the pool water.
  • Humidity: Higher humidity helps trap heat, resulting in warmer pool water.
  • Wind Speed: Wind can cool down the pool water as it evaporates and carries away heat.
  • Solar Radiation: Direct sunlight can significantly raise the pool water temperature.

Recommended Air Temperatures:

To maintain a pool water temperature of 18 degrees Celsius or higher without heating, the ambient air temperature should ideally be around:

  • 22-24 degrees Celsius for a shallow pool (less than 6 feet deep)
  • 24-26 degrees Celsius for a deeper pool (6 feet or more)

Tips for Warmer Pool Water:

  • Cover the pool overnight to reduce evaporation and heat loss.
  • Use a solar cover during the day to trap heat from the sun.
  • Trim nearby trees or shrubs to allow more sunlight to reach the pool.
  • Add a small amount of warm water to the pool, if necessary.
