PredictWind is a top-rated app for sea swell forecasting, boasting incredibly accurate wind direction predictions and generally close wind speed estimations, surpassing other weather apps in daily accuracy. While users consistently praise its superior predictive models, particularly for detailed information on wind, waves, and gusts – covering regions from Cabo to San Francisco Bay – the app's performance can be inconsistent, with reports of frequent crashes and slow navigation, especially on older devices. Despite these performance issues, the comprehensive data and advanced features make it a worthwhile choice for serious sailors, provided you can overlook the occasional frustrating lag and clunkiness. Ultimately, the superior forecast accuracy often outweighs the usability drawbacks for many devoted users.

5. Buoyweather

Download:

Cost: Free (Free), Buoyweather Premium ($9.99/month)

Buoyweather is a mobile app for sea swell forecasting, offering detailed 2- and 7-day predictions of wind, waves, and tides at any offshore location. While users praise its ability to pinpoint forecasts for precise locations, making it invaluable for planning offshore trips ("Choose a Forecast Location at Any Point Offshore"), recent reports highlight significant server issues and data inaccuracies, leading to frustration ("constant error messages," "wave information not available," "wind and wave data is misaligned"). Despite its potential as a powerful tool for sailors and boaters, the current instability and high subscription cost ($80/year) are major drawbacks, causing some users to consider canceling their memberships unless substantial improvements are made. Ultimately, the choice to use Buoyweather hinges on whether its location-specific accuracy outweighs its reliability issues.
