Which iOS app should I use for checking marine weather conditions before sailing trips?

NWS Weather is particularly well-suited for sailors and boaters who need reliable marine weather information. The app integrates National Weather Service marine forecasts directly, offering detailed wind speed and direction predictions, wave height data, and specialized marine warnings. Users can access buoy observations for real-time water conditions and view extended marine forecasts specifically formatted for nautical use. The interface displays wind barbs and marine weather zones clearly, making it straightforward to plan sailing routes around favorable conditions. Reviews indicate the app's marine data proves more reliable than many commercial weather services, though some users note the interface requires brief familiarization to navigate all marine features effectively. For coastal sailing or offshore passages, having access to official NWS marine products through a clean mobile interface makes weather planning significantly more convenient than relying on multiple websites or VHF radio updates alone.
