Fastest way to heat pool--cover or no cover in sun?

Here's somewhat of a dumb, open-ended question:

We've been blessed with somewhat summer-like weather
these few days (for the time being), and I'm interested
in getting into the water as soon as feasibily "warm".

Assuming all else being equal, what heats an inground
pool faster:
- direct sunlight with a pool cover completely off during
midday overhead sun (~10am-2pm), or,
- leave an opaque vinyl pool cover on the whole time the
pool is not in use

assume little or no wind and water temp is colder than ambient
air temp.

anyone have a rule of thumb or gut feels based on
experience?

thanks
aaron

There would be no solar heat gain with the opaque cover in place.

My buddy had a 16x32 above ground pool, and the first year he installed it all he had for heat was the solar cover, clear plastic with the bublles (like the bubble wrap they use for packing) now if he left the cover on all day without removing it, the water temp would rise in a hurry because it's basically like a blanket keeping the heat in, but they was a down side also. While the water temps would get so warm it would be like getting into your bathtub, it also promoted algea growth, so we had to keep close watch on the ph levels and chlorine levels plus they scrubbed it everymorning to boot. Now we installed a black solar heater that's plumbed inline with the pump and that made a big difference as it moved the "jump into pool date" up about a month, since we're in the midwest. I'd definately looked into the transparent bubble wrap solar cover and if you want to keep building heat-leave it on.

There's "some" heat gain even with an opaque
cover albeit not as much as a transparent bubble
cover. Supposedly it's about 40% of that of a
clear cover. :-( I do notice that the topmost thin
layer of water just beneath the cover gets pretty
darn warm in hot sun.

In my situation, we have an automatic cover that
spans 60ft in length (lap lane). I don't really have a
convenient option to replace it with a bubble cover.

I also have solar installed, and that appears to
help if I leave the pump running for quite a number
of hours everyday. However the weather hasn't been
terribly consistent. It was in the 80's for 2 days
over the weekend, now it's raining and back in the 50's and
low 40's at night. had the water temp up to 75-77F
for 3 days, but now, water temp is back down to
about 65... sigh...

Holy moly that's cold water. I'm not a pool expert by any means and actually it's cheaper and easier to have a friend with a pool where I'm from than actually having a pool since they're only usable for about 3 maybe 4 month's of the year. You've got a monster pool, so hopefully somebody with some experience can pipe in.

Heating pool

The homes where I used to live that had pools, we did the spring cleaning of the pool area and its landscaping and removed the vinyl winter covering. We replaced with the bubble plastic cover and raised the the pool temp in no time for swimming. Until area temps rise to the level to maintain desirable pool temp, the bubble cover will collect heat from the sun and maintain pool temp. The bubble wrap cover will speed up temp levels and extend swimming season.

the fastest way would be to put a solar bubble cover on and turn the heater on in addition ,
