Marine Forecast Gyx (2024)

FAQs

What is the best marine forecast model? ›

The ECMWF is generally considered to be the most accurate global model, with the US's GFS slightly behind.

SE WINDS 5 TO 10 KT, BECOMING S IN THE AFTERNOON. SEAS AROUND 3 FT. WAVE DETAIL: SE 3 FT AT 7 SECONDS AND SE 2 FT AT 10 SECONDS. PATCHY FOG IN THE MORNING.

Before any boating trip, you should check the short-term and long-term local weather forecast as reported on the radio, TV or Internet. You should always factor these weather forecasts into your preparations as you make your trip plan.

Most commercial radio and television stations give marine weather broadcasts during the boating season, with updates several times a day. Other sources of weather information include NOAA, the National Weather Service, and other government agencies.

ECMWF. The European Center for Medium-Range Weather Forecasts (ECMWF) model is another global numerical weather prediction model that is highly regarded for its accuracy. It employs advanced data assimilation techniques and sophisticated numerical algorithms to simulate atmospheric processes.

The ECMWF generally outperforms the GFS statistically, but there are instances where the GFS may perform better for specific events. Let's summarize the main differences between both leading weather forecasting models: Resolution: GFS runs at a lower resolution than the ECMWF model.

But generally for surfing, you want light offshore winds under 15mph for clean, groomed waves. Anything more than that (say, a gusty offshore wind over 25mph) will make it harder to paddle into waves and, on weaker swells, harder to generate speed on the waves.

The Offshore Drilling Rigs Market size is expected to reach USD 73.20 billion in 2024 and grow at a CAGR of 6.78% to reach USD 101.63 billion by 2029.

The ocean heats up much slower and becomes relatively cooler than the beach making it a high pressure zone. The air moves from the water to the land each morning forming a sea breeze. These pressure zones might equal out later in the day and the winds may diminish.

How much wind is too much for boating depends on your boat and your skill level. Vessels less than 25 feet need to head for shore if winds start approaching the 10 miles per hour mark unless they are constructed and equipped for such weather.

What wind speed makes the sea rough? ›

Sustained winds of 22 - 33 knots (Beaufort Scale 6 - 7) capable of driving seas of 10 - 18 feet. At Beaufort Scale 6, larger waves form. Spray is present with white foam crests everywhere. At Beaufort Scale 7, even larger waves form, but seas begin to heap up.

Some examples of dangerous weather that can occur include strong winds, rough seas, lightning and waterspouts. Generally, wind gusts of 34 knots (39 mph) or more are often strong enough to capsize small boats, especially when they catch the boater off-guard.

The National Weather Service (NWS) Marine Weather Services Program offers a broad range of marine forecast and warning products in graphical and text (low bandwidth) formats (See Tabs above).

Chop is the cresting of waves created by the wind. You might also describe what you're seeing out on the water when it's choppy as being lumpy, bumpy or messy with the water surface moving up and down and side to side.

Safety First: Minimizing Risk

Slowing down when passing recreational fishing boats isn't just courteous; it's a critical safety measure. The primary reason is the reduction of risk. Fishing boats are often stationary or moving slowly, with occupants focused on fishing rather than oncoming traffic.

NAM vs HRRR: accuracy

In general, yes. The former surpasses the latter in the main parameter of the accuracy of weather models — the resolution, as much as four times (3 km vs. 12 km).

The model with the highest success ratio (rewarding correct genesis forecasts combined with fewest false alarms) was the European (ECMWF), followed by the UKMET, the GFS, and Canadian models.

The European Centre for Medium-Range Weather Forecasts model is highly regarded by meteorologists around the world. ECMWF's HRES model consistently rates as the top global weather model and offers a record breaking 9km resolution.

Rainfall prediction is a common application of machine learning, and linear regression is a simple and effective technique that can be used for this purpose.
