Park them into wind - The gust front of a thunderstorm will mean you find it where you left it.
Run them up into wind - Avoid stone damage, help cool the engine, help get some cool air circulating through the cabin, dont damage the door you have left open to let some breeze through.
Keep the controls into wind when taxiing, take-off and land into wind!
Try hot starting some aircraft ie C310 in temps above 40 degree's and you will know that 1-2 kts of headwind might just make the difference.
