Yeah they generally do. Its normally only the E/SE that blow all night and generally they will blow pretty cold too, even in the middle of summer.
MISSED and I were out spotlighting in January and it had been 35+ during the day and the easterly blew up and he spent the night complaining how cold it was and kept wanting to put the heater on in the car. I told him he was soft, but he threatened to make me walk the 40ks home, so I left it at that
Oooh a bit of suss play going on in that spotlighting rig
Haha, reminds me of when I was working in Conargo and the roo shooter from Deni use to drop into the pub on his way and the publican (fairly handy female) would go with him some nights for the ride we use to find the odd rain coat in the shearing shed
