Just tested chlorine and it's 95F degrees out. Readings are too high?

I've changed nothing about my process except for the time of day I just tested. Normally I see about 4 or 5ppm left every 3rd day. Today I tested on a 95F degree day at 2pm on a day with full sun and my chlorine is reading 30+ppm! My testing kit is reliable, it's a FAS-DPD test that has never failed me. So, is there something about the temperature of the water or the fact that the sun is hitting it that's changing the readings?

Be sure you did the test right. Or you added alot of chlorine since the last time you tested.

Ok, I just figured out that I used the wrong reagent while testing chlorine. So the full sun and heat did have an effect, it was just on my brain...
