In drag force, yes, but in this case, you are taking the 3% penalty and aren't getting the partially offsetting 1.7% increase in distance per unit time that 60 gives you over 59.
Note that it's 3% per 10°C delta so, for a 40°C swing (say 30°C/86°F summer to -10°C/14°F winter), that's a 12% difference in aero drag force.
