Windy App
I really recommend the windy app for providing local weather forecast, for winds, tides, sea state. These widgets give you a sample of the full information available, but the app gives you more. The free version with ads is good and does the job, but I decide to purchase the pro version as it has become an essential tool in my navigation and planning.
