Best time of day to view seabird rookeries

[TwoCalBears]

We're getting ready to book a wildlife viewing cruise out of Kodiak when we are there on the Royal Princess in July. These excursions leave both at 7:30 am in the morning and at noon. Which would be the best time of day for this kind of excursion? We are particularly interested in seeing puffins: does anyone know if the birds would be more likely to be in their rookeries in the morning or the early afternoon? And what about weather? Are we more likely to encounter rain or fog in the morning?
