My St. Augustine grass has flourished all summer. In the last ten days my yard has developed large circular brown spots all over it. I water it a bit every day. It hasn't been cool enough for the yard to start dying yet; I live in Texas. Does anyone have any thoughts?

You may brown spot. It is a fungus that can grow in St Augustine when the night time temperatures get in the 60's and 50's. You need to apply some Fungaway fungacide. It is available at Lowes, HomeDepot , Walmart and many nurseries. That will stop it growth its this year.
Next fall, when the night time temperatures get into the mid 60's apply the fungaway before the brown spots start and you can prevent it causing the same problem.
You can also get a fungus called "take all". It is called this because it kills both the leaves, stems and roots. It starts to grow under the same conditons as brown spot and the Fungaway will control it also. It tends to start with night time temperatures in the 60's.
Brown spot usually only kills the leaves and you lawn should bounce back next spring. You can usually tell the difference between the two because the brown spot tends to look more like a ring than just a spot.
In either case the treatment is the same.

I live in South Texas and deal with St. Augustine a lot. What your grass has
is called "brown patch" = a fungal disease. It happens a lot this time of year.
The nights are getting longer and cooler. It's caused by too much water and
the moisture doesn't have time to evaporate. DON'T WATER !!! You can put
a fungicide down if you want. I don't like chemicals, though. We use some
good organic compost. It'll go away next spring. Some people say, " yeah
but it always comes back in the fall." But they'll make the same mistake next
fall. Just lay off the water - do what you can to make sure your grass stays
dry during the night

Watering "a bit every day" doesn't reach the roots. Water 1 inch twice a week.
Florida has a lot of the big brown spots on St. Augustine also. We have mediocre grass but have a service that sprays every two months that keep it looking good.

Sure sounds like brown patch fungus. Spots are usually fairly uniform in size. Watering every day is too often and can cause a fungus! DEEP waterings 2 or 3 times a week is much more effective. (45 min or more each zone). You will need a fungicide to eradicate it now but it may never be the same.

You should never water anything every day, except maybe plants in clay pots in the summer. You need to give the roots a chance to breathe!

It could be Chinch bugs.

It is either fungus, chinch bugs or dog urine.
