check the timetables (on the city web site) if high, bring wellies

Timetables? Tide...

Yes, I've been in Feb a few times and right after Carnival. I prefer Venice in winter. It's a great time to visit because of the lack of big crowds. Be prepared- the weather can be unpredictible, so be sure to bring good footwear, outerwear, layers,scarf, hat, gloves, and an umbrella. If you don't mind bundling up, you will enjoy it.

kappa, sorry yes, tide timetable.
