They offer aqua zumba at the gym. the water temp is 87 degrees. i will be 30 weeks pregnant this thursday. is it safe for me to do the class?

Sure: Nothing better than exercise in an external water environment which takes he pressure off of the fetus in the internal water environment(amniotic fluid). Pregnancy exercises such as this increase your fitness level to endure and facilitate labor by shortening it during the 2nd stage(pushing). If your bag of water ruptures, then tell your OB MD immediately and stop the exercise program.
