POOL WATER TEMPERATURES
FOR AN UNHEATED OPEN AIR SWIMMING POOL
Water
temperatures have been obtained from a small Castle Hill
open
air salt water swimming pool about
1 metre
under the water surface.
This pool has a water surface area of 30 m²,
water
volume of 40 m³, no
water heating installed, no
pool blanket cover, no
shade cover after 9:30 am, normal
wind exposure and light
bottom colour.
The table below sets out this
Castle Hill's pool water temperatures during
September 2011. A table of current pool water and beach
ocean temperatures are also provided and are updated on a weekly basis. Click
here to view the table of pool water temperatures for January
2012.
The pool water temperatures would be different for pools in different locations and with different distinguishing characteristic features.
By a quick inspection of the
table below, you will see that the pool water had been well and truly chilly all through the
September period and the temperature had fallen considerably short of the
leisure swimming temperature range, which is ideally between 25° and 28°
C. This situation could have been improved.
As the water in the pool has been cooling mostly
overnight or due to wind anytime during a
day, a solar pool blanket cover would have prevented this happening. Then minimal pool heating could have raised the temperature to
KEEP the CHILL OUT. An
installation containing a pool heater together with a solar pool blanket will then extend the use of your swimming pool in
AUTUMN at lower running cost.
We use the September 2011 pool
water temperatures below to illustrate how pool heating can
extend the use of you swimming pool into Spring and Autumn at an
affordable running cost.
