Is it in the summer? Spring? Urban complex (à la Picton) or 100% forest? Is it 30+ celcius or 15 with heavy showers? Are you tasked with patrol, direct action, reconnaissance? Etc...
To add to this, it'll also be directly affected by YOU and your body, I've seen guys take -25 weather in a polypro shirt and rain jacket as if it was a slightly chilly day. If this is you, then you'll pack differently than someone who is still cold with 16 layers on. But like Conker said, seriously consider your role in the Op as well as possible weather
