Relative humidity depends on the temp as much as the amount of water in the air. Check on the weather site for Dew Point instead- that is the absolute amount of water in the air independent of temp.

64° at 89% RH = 61° DP

71° at 76% RH = 63° DP

I don't think your car will notice a diff in 2° of dew point, nor will you. The diff between 64 and 71... I'd say that was all butt-dynoitis and there was not real difference. Were you in a lot of traffic on the ride home? If you were in some stop n go traffic and your intake got heat soaked, that'd cause some issues.

That's not a real high dew point and is pretty much a perfect temp for the ride home. Your car will like that a lot better than 90°+ and a 70°+ dew point like in the summer though. That's the nasty muggy weather.
