I live in Florida and the weather has been warm. However, my pool is still a little cold. We've had several days in high in the high 80°s but the temperature of the pool water is still cool. I'm thinking about adding a pool heater. How long would it take a heat pump to raise the temperature 10°?

There are a lot of variables that go into determining how long it will take to heat the pool with a heat pump. I'll use my pool as an example to give you an idea. I have a 95k BTU heat pump and I'm also located in Florida. I have an unscreened 10k gallon pool that gets a lot of sun. Without running the heat pump, my pool temp in April has been 75°-80°.
I decided to run the heat pump yesterday so we could swim in the afternoon. The temperature of the water at 9am was 76° and the ambient air temp was 67°. By 2: 30pm, the temperature of the water was 87° and the ambient temp was 90°. So in 5.5 hours, the temperature rose 11° (2° per hour).
The 2° rise per hour was helped by the warm sunny day. I have run it on cloudy days in January and only got .5° to 1° an hour. The ambient air temperature really plays a big role.
I don't use a solar blanket but that would really help if you want to maintain the temperature over several days.
Pictured below are a couple of screenshots I took while the heat pump was running.
