Mostly true. Somewhat closer to the Sound would be even better.
One more comment to the OP.
Make sure your garage stays as cool as reasonable. A south facing, not vented garage I'm aware of would stay quite hot, being as much as 20 C warmer than outside. Put a thermometer in your garage, and compare with outside temperatures. If you have a problem, consider adding insulation to the doors, a high and a low vent, putting a box fan in a window during the summer on a timer so it runs at night, if you have a window that is, or similar.
