Do unheated swimming pools heat up as the weather gets hotter & pretty much stay at that temperature for the hotter months so they are ok to swim in? (PS I'd like an answer to this question, not whether I'm asking a "potentially silly question" question!!).

The warmth of the sun will heat the water, and the ground around the pool (if it is a sunken one) will have an insulating effect that will keep some of the warmth in the water when the temperature drops (ie overnight or if the weather gets colder).

They must do, to some extent - even the sea gets warmer through the summer. I suppose it depends how cold it gets at night; those insulated covers are probably essential if it gets chilly.

They certainly get warmer as the weather gets warmer. However it is a big volume of water to heat so they do tend always to be a bit cooler than the outside temperature.

If they have a cover then they will tend not to lose so much heat overnight.

There is no such thing as a silly question, only silly answers!

umm i dont know but have been to various outdoor paddling pools and even on hottest days they were still bloody cold. But in a good way, as the weather was soo hot the water was cooling! (Bearing in mind i live in Scotland so it never really gets scorching hot and these hot days are far and few between!)

friends (in a different climate) have a pool that they can use from late April to late October.
they have pretty cold and frosty winters, but warm summers.
the pool has got a slide-away roof, so they can use the pool even in bad weather and the warm air stays warm above the water as well. the water has to be treated and partially replaced regularly or it would be pretty disgusting.

If they are completely unheated they will heat up a bit in good sunshine/heat and over a long period of time this will have a cumulative effect - which is why end of summer is best for unheated pools and the sea and often even into sept / oct

In portugal last year the pool was still too cold for me as was Spain the year before but when we went to Antigua the unheated pool and the sea were a gorgeous temperature (think warm bath)

We had an outdoor, unheated pool in our garden when we were growing up. As kids, we'd be in it as soon as the ice broke :o It got warmer throughout the summer with minor ups and downs in temperature.

GENERALLY will retain heat as ground acts as insulator, the sea around britain is at its warmest around september / october as takes long time to heat up and cool down at its coldest february - april so even a really hot april day the water will be colder than a chiller september day

Treating the water is pretty straightforward. When we had an above ground garden pool it was rather nice to fiddle about with the water, testing it and mixing in the chemicals. Most of the reasonable above ground pools come with a filter. It is just a case of putting that on for the times when people arent in the pool.

The hotter the weather is, the colder the pool will feel anyway, even if it has warmed up a bit Wink

the hotter the weather, the more people in the pool, meaning more people weeing in the pool, making the pool warmer.

you may also find that the depth of the pool increases correspondingly.

You will also find that it sometimes depends on what the pool is lined with... plain concrete type ones tend to warm up (and retain heat) better than the ones that are totally tiled.

I'm also loving toxtethogrady's theories!

It depends on the size of the pool. Smaller poll = warmer water.

Unheated pools are always cold. For example even in mid summer Florida residents heat their pools. Last year in July we were in Morrocco 40c during the day. The pool was baltic in the morning though got bareable by 1pm. I used to go to Majorca in the October break, gorgeous weather but only the hardy and the kids would go in the unheated pools (emerging blue)

Depends where you live. When we get a lot of days over or close to 40 the pool stays warm all night and is like a bath tub not in the least cool and nice to get in.
Mostly with weather in the low to mid 30's the water cools a bit overnight and feels fine by mid day. But then we don't get below 30 at night a lot too.
