I bought some coconut oil for the first time the other day, and while the label says to store it in a cool dark place, I'm in a relatively warm climate with no air conditioning. As a result, while I'm able to store the oil in a dark place, it often gets warm enough in the late afternoon to liquify. The oil solidifies again after dark, and I'm naturally wondering if this almost daily process is damaging the quality of the oil within the time it'll take me to finish consuming it (probably no more than a couple weeks).
Nah, coconut oil will turn to liquid at 76 degrees. One of its good properties among many is that it is stable up to plus or minus 450 degrees and turns rock solid in the fridge.

In tropical climes, it is liquid all the time.
Make sure you buy virgin coconut oil as it is the best quality. I understand some less quality does break down sooner under heat.
As long as you use it up in a reasonable time, it's no problem. It going from solid to liquid doesn't effect the fatty acids negatively. Same with butter. Safe at warm temps, but can go rancid eventually, and will go rancid in higher temps more quickly.
I have to keep mine out even when it's hot, because if I put it in the fridge it's rock-hard and damages my kitchen implements when I try to get some out for cooking. Never had a problem.
I keep it in the fridge and use a heavy metal spoon to scoop out what I need. As long as you keep it in a small jar, scooping out what I need is not a problem. I buy a large container but pour what I need in a small jar that I keep in the fridge.
my father used to cook everything in coconut oil when i was a kid. the bottle sat on the back of the stove and went through many state changes each day. in the winter he would roll the glass bottle over the burner of our gas stove to melt some to pour out. it is very resilient stuff!
I just keep it in the cupboard, at room temp. Our house gets up to around 78-80F in the summer (like now) and the oil turns liquid. I have never noticed any decrease in quality. It's actually a lot more convenient to have it liquid. Maybe I should move to the tropics...
Just as an FYI...Tropical Traditions (if you like them on FB you get all the scoop about their sales) has awesome coconut oil...virgin, organic..etc. I bought 2 gallons for 65.00 which for high quality coconut oil is a great deal...It's great that coconut oil is so stable cause 2 gallons is a LOT of oil! But, by the same token, we use it not only for cooking but for our skin, for sun protection, for LOTS of stuff.
