Buoyweather Now Offers Multiple Forecast Models

boat_runningBuoyweather users now have the ability to toggle between two global forecast models on the recently updated forecast page. Along with the classic 7-day model, users can now view Buoyweather’s 16-day model. This new model provides 16 days of wind, wave and tide forecasts, as well as precipitation, sky conditions, air temperature, barometric pressure and moon phase. This is the first time Buoyweather has included air temps and rain chances to provide users with a more complete weather forecast wherever they boat.


While both models are derived from NOAAs Wavewatch III wave forecasting, there are some regional differences in forecast resolution between Buoyweather’s LOLA model and the forecasts produced by the National Centers for Environmental Prediction (NCEP). Buoyweather uses both models to produce a written forecast for any lat/lon, along with wind and wave graphs in 6-hour increments.

The biggest difference is that Buoyweather’s proprietary LOLA model offers forecasts out to 16 days, while the NCEP model only offers a 7-day forecast. Both models provide accurate forecasts around the world, but keep in mind that long term forecasts can change over time, and shouldn’t be relied on for long-range decision making. It’s recommended that users check forecasts daily for updated information whenever possible.

Our team of forecasters and engineers is continually improving the modeling behind the LOLA forecasts to enhance both resolution and accuracy, but since we provide global coverage for any offshore lat/lon point in the world, user feedback really helps us  identify any local areas where the forecast could be enhanced. Please contact us if you have any issues or additional questions.



1. Why offer more than one forecast option?

Some models perform better than others in certain areas, and since Buoyweather allows you to retrieve a forecast for any lat/lon in the world, we wanted to give users a choice to view the model that best suits their needs. Also, many users like to compare forecasts from a number of different sources before they head out on the water.

2. Why won’t the model show inshore wave heights?

Buoyweather is first and foremost an offshore marine weather service. Neither wave model is intended for use inshore or in protected waters. In some remote inshore areas, the 16-Day LOLA model may return a wave forecast for the nearest offshore point (although the wind and weather forecast will still be valid for your selected lat/lon). The 7-Day NCEP model may not return a forecast at all in these areas or you can move the cursor offshore to get an accurate forecast nearby.

3. Once I choose a forecast model, will the site remember?

Yes. Furthermore, when you later check the Buoyweather forecast on the iOS or Android app you’ll see the latest forecast from your chosen forecast model.

4. Are the forecast times in local time?

Yes, the times shown in the forecast graph may differ depending on the model selected, and what part of the world you are in, but are shown in local time.

5. When does each model update?

Both forecast models update four times per day — at midnight, 6 a.m., noon, and 6 p.m. GMT.
