Marine weather plays an important part in the enjoyment of a boating trip. Often local marine weather forecasts are unreliable. Why not put PredictWind's Free Forecasts to the test on your next trip? PredictWind will help make your trip faster, safer and more comfortable.

Often local marine forecasts are conservative and report the expected maximum wind speed over a large region. With a PredictWind forecast map you can see the whole region, and know exactly where to expect the areas of high wind speed to help plan your trip.

Plan your day trips with an accurate wind forecast

Day Trips

The PredictWind Basic Package is great entry level package for those not venturing too far from home, but want the most accurate marine weather forecast available.

The wind speed and direction graphs utilise the most accurate 1km resolution wind forecast, and although you cannot see the 1km resolution maps, you can view the general weather situation with the 8km resolution maps.

You can also access this information in text format on your mobile phone at no extra charge.

The wind weather plays an important part in detemining the speed and safety of your trip

Coastal Trips

PredictWind's Standard Package is suited for coastal trips, where you want to see how the weather pattern will vary over the whole area. How close are the strong wind areas? Where are the best places for anchorages and shelter? Where are the best overnight anchorages? What is the best course and time to depart? You will be surprised at how viewing a forecast wind map will help you plan the trip with confidence.

Free GRIB viewer

Use the Free GRIB viewer to automatically upload the Predict Wind weather forecast onto the chart. This tool is ideally suited for retrieving the forecasts over slower wireless internet connections and will ensure you always have access to the forecast when there is no internet connection available.

Mobile Phone site

You will have also have access to the PredictWind Mobile Service, so you can get the latest text forecast on your mobile phone at no extra charge even if you don’t have access to your computer.

Weather Routing

The Professional Package now includes the world's first  online weather routing. Simply drag the start and end waypoints on the Google map, and the PredictWind server will plan the fastest route or the most comfortable route for your boat using the high resolution 1km-8km wind forecasts.  The comfort route allows you to avoid motoring in strong wind and wave conditions. You decide your tolerance level, and the PredictWind routing algorithm will avoid these regions in the forecast if possible. You simply need to enter you boatspeeds in various conditions. There is no software to install, and the optimal route is calculated for both PredictWind forecasts.

The routing algorithm is also clever enough to avoid the land, right down to the 1km resolution level. So now you can can accurately see your optimal route and know exactly what conditions you can expect along the trip.

Departure Planning

What is the best day for depart on your next coastal passage? You will be spanning different weather patterns, and this powerful tool will quickly summarize the wind conditions you will receive if you left on Day1, Day2, Day3, or Day4. Simply drag the start and destination waypoints on the Google Map, the weather routing algorithm will calculate the fastest route  (avoiding the land) and summarize the wind forecast data for the next 4 days of departure.

Offshore Passages

PredictWind can provide a 9 day marine forecast using the 100km resolution model for any region in the world. When offshore and away from land effects, it is not necessary to get a high resolution forecast. However you can be assured to get the best forecast available using the same technology that is used to generate the high resolution forecasts. The reduced smoothing in PredictWind’s weather model you will allow you to see wind features that are not picked up by other weather models. In addition we use two data sources for the weather model, to produce dual forecasts for comparison. The closer the wind forecasts, the more confidence you can have in the accuracy for your comfort and safety.

Free GRIB viewer

Use the Free GRIB viewer to automatically upload the Predict Wind weather 100km resolution forecast onto the chart. This tool is ideally suited for retrieving the forecasts over slower wireless internet connections and will ensure you always have access to the forecast when there is no internet connection available.

Weather Routing

The Professional Package now includes the world's first  online weather routing. Simply drag the start and end waypoints on the Google map, and the PredictWind server will calculate the fastest route or the most comfortable route for your boat using the high resolution 1km-8km or 100km wind forecasts.  The comfortable route allows you to avoid motoring in strong winds or large swells. You decide your tolerance level, and the PredictWind routing algorthim will do its best to avoid these areas. You simply need to customise your own polar curve for your boat. There is no software to install, and the optimal path is calculated for both PredictWind forecasts.

The routing algorithm is also clever enough to avoid the land, right down to the 1km resolution level. So now you can can accurately see your optimal route for coastal cruising - for Comfort or for Speed

Reduce Communications Costs

Whilst offshore, getting access to the internet is expensive with satellite communications, and file sizes are limited with SSB radio data services. PredictWind has the ultimate solution for this problem -   Routing service via email .  The same weather routing package is available via email. Simply email your start and end destination waypoints, and the PredictWind server will email back the optimal route for both forecasts. The file size is minimal , and so will be your communication costs!

The Professional Package is suited for offshore passagemaking

For offshore passages make use of the GRIB files, and a GRIB viewing program

Also an acclaimed navigator on racing yachts Robbie has sailed 13 Transpacs from 1975 to 2007 including navigating aboard Andrews Turbo 70 Victoria, Andrews Turbo 70 Magnitude, SC 70 Mongoose, Petersen 68 Cheetah, the Transpac 52 J-Bird III, Andrews 56 Medicine Man SC70 Skylark and Kernan 70 Peligroso.

" As a former yacht racing navigator for 35 years, the process of obtaining precise wind information has always been at the core of my planning and execution, of course. Now, as a professional Captain aboard large motor yachts, I am often frustrated with the minimal wind information available in the wheelhouse. Mast Head Units are typically mounted between two communication domes or radar scanners, for example! Sure, on a motor yacht at sea we don't need to know subtle wind shifts, but it is still extremely important to me to know wind speed and direction as accurately as possible, especially on a black night. I have always planned my passages using the usual Internet sites for GRIBS and buoy data, but now with PredictWind.com, I have for the first time the ability to view High Resolution Local information accessible during the voyage. Do I continue down the Rhumb Line or should I close with the beach because a hard offshore is predicted at 0200? With PredictWind.com these decisions are now much easier! It's almost like having a new wind instrument on the bridge! "

" I have been fizz boating for forty years and have a healthy respect for the sea and variable conditions. My main concern is always the weather, not the temperature or rain just the wind. My minimum planning speed is 25 knots I don’t want to be caught out in strong wind and wave conditions with 4 tons bouncing out of the water.

I am now using Predict Wind as my main source of information before every trip and have been impressed with the high percentage of accuracy. "
