Can temperature affect the accuracy of my hydrometer?

Yes.
Assuming your hydrometer is calibrated for 20C it will read denser below 20C and less dense above 20C by about 0.06 Brix. So a wine that reads 12.4 brix at 15C is actually 12.1 Brix.
This is the conversion factor I use, although I've seen a table where the conversion is not quite as linear.
