The weather can be glorious, grey and cold, or simply miserable. I have experienced trips with nothing but sunny days and temperatures allowing shorts and sandals. Other times have brought rains that equaled anything I have seen, when it seemed the sea was both above and below. Sailing through narrow, rocky passages with nothing but radar to see the shore a few hundred feet away, shrouded in fog.
You take what you get on a trip, no way to reschedule now. Rain or shine, fog or mist, each can be beautiful in their own way to an traveler willing to enjoy the experience, whatever life brings.
