We've been twice before, but a bit later in the month (July 19). This time we'll be sailing on July 8. Layers, as most have advised, are key. If your feet tend to get chilly, I'd advise a couple pairs of lightweight wool socks as well as mittens. I usually take a shawl for late evenings around the ship. Hot news .. Anchorage had record high temps in the 80's the last week or so, so even I am conflicted, lol. And .. it might be early for spawning, but we went on a bear watch last time and didn't see one bear .. they feed in the early morning and then nap a LOT, I guess. But whales were excellent.
