Dumb question - should I be using a heavier weight oil in the summer, temperatures almost never below the 90s.

After I changed my oil this spring the ticking I was hearing went away, but as soon as the temperatures shot up it is always there now. I'm wondering if the heat is just causing the oil to thin out too much.
