We went in August 2016. Most of the cruise was misty/rainy, 50s/60s for temps. Vancouver was low 70s. Only day we needed shorts was debarkation day. We felt comfortable in jeans and short sleeve shirts inside the ship. While it was heated, it wasn't to the point of needing shorts inside. You'll just need to check weather before you leave, and bring a little of everything for clothing... could be hot and sunny, or more 'typical' cool and rainy weather. Despite the cool weather, WE still went in the heated pool. Lol, that's really where the temps you're used to will show...which people are bundled up outside and which are in the pool.
