August in Melbourne and region is usually cool. But Melbourne is a 4 seasons in one day sort of place.
On average the temp drops right off once the sun goes down. Nights are usually around 5-8 C but can drop to -1 or 2 if a cold snap hits or your out in the yarra Valley etc. Day time 14-18 is about average but you may get days up to low 20's or low teens. T shirt, shirt and windcheeter should do along with a light rain coat. You can always get cheap jackets etc. At the Vic Market and the like. Cold winds come in from the south and warm weather from the north.
Do you think a long john is necessary?
Being from Simgapore you will be unaccustomed to the cold and will feel itinerary than locals. Long
Johns are a good idea. August is often the coldest month of the year in Melbourne.
If you are planning an evening out in the open at Philip Island, long johns together with scarf, beanie, gloves and lots of layers are a must. It will be freezing! And take a blanket to sit on.
Thanks Eva! :)
Do I need to bring umbrellas/ponchos?
Yes, an umbrella is really handy! You will want to layer your clothes, as it can be cold out. I'd suggest long sleeve t-shirts & fleecy tops, with maybe a light to medium jacket over top. You won't need long johns in Melbourne, but they will keep you warm watching the penguins come in on Phillip Island. A hooded garment or beanie, & maybe a scarf & gloves will help with warmth too. It can also get really cold along the GOR, so layering there will be good too.Edited: 3:18 am, July 08, 2013
Thank you all for the helpful replies!
I guess I will be wearing long john, a thick tee (& jeans), a hooded jacket and a scarf to fight the cold.
It's always so warm in Singapore that the coolest I experienced is at 27C during the monsoon season. I better layer myself up in Melbourne!
One thing to watch with jeans is that if they get wet, they are really uncomfortable (& cold). I prefer to wear Ponti pants when travelling in Winter as they are a bit warmer & they dry quicker.
If your not used to the cold you will need to rug up. The cold wind can make it feel sub zero. Block the wind out and you feel warmer. sitting on the beach will be very cold. Long john or thermals are a good idea for nights out. Then again a sunny day and feels very nice. As said staying dry is very important. a light rain jacket in the bag is a must, it will keep you dry and block the wind.
Of course Melbourne is going to be a great place to be at! And you are right, it's the changing weather which we would like to experience too! :)
Looks like I will have quite a bit to pack for the trip!
