How does nautical weather supplement the weather?

The premise is that you use the Iridium Go satellite network box, which is the most portable and best communication tool. The weather function inside can check the weather forecast of your location in the last three days. The information is very comprehensive and can be customized. Every three hours, the wind direction and weather waves are very high, and the probability of thunderstorms is also very high. The accuracy is still very good.

2. Computer Software: Forecasting Offshore Wind Power (predictwind.com)

If you use Iridium Go, you can use this software to download the latest data of several wind forecasting models on your computer. If you set the starting point and the ending point, you can automatically calculate the best route. This is almost our daily homework when we sail across the ocean, which determines our next navigation strategy, whether to turn around from the wind tunnel or develop momentum to accelerate our progress. The accuracy depends on the prediction model, and the accuracy of different models is different in different regions.

3. Radio station

You can receive weather forecasts on the radio, some are official, some are folk, but in general they are offshore. Due to the limited transmission range of VHF, signals can only be received by HF radio in transoceanic navigation, which is a more traditional method in modern society and expensive equipment. However, if there are already high-frequency radios, special modems and Grib (Grided Binary or General Regulated-Distributed Information in Binary Form) analysis software on board, then radio is a reliable way.

4. Meteorological mail service

If you have money, please ignore all the above and buy professional meteorological services directly. There are very good weather service companies abroad, which can provide you with extremely detailed weather forecast and navigation advice, and even track your navigation route and actively inform you to change your route before danger comes. In the Indian Ocean, we used this service to provide you with weather forecast and navigation advice for the next five days by 50 euros e-mail.
