Small Craft Advisory: Meaning, Hazards, and Safety Measures
Hey readers, welcome to our comprehensive guide to understanding the “small craft advisory.” This marine weather warning is of paramount importance for anyone planning to venture onto the water, so let’s dive right in and explore its meaning, hazards, and safety measures.
Understanding the Small Craft Advisory
A small craft advisory is issued by the National Weather Service (NWS) when sustained winds of 22 to 27 knots (25 to 31 mph) and/or seas of 3 to 5 feet are expected or occurring. These conditions can be hazardous for small vessels, including sailboats, fishing boats, and personal watercraft.
The advisory typically covers a specific coastal area or offshore region and can remain in effect for several hours or days. It’s important to note that the thresholds for issuing a small craft advisory can vary slightly between different NWS regions.
Hazards Associated with Small Craft Advisories
The primary hazards associated with small craft advisories include:
- High Winds: Strong winds can create rough seas, making navigation difficult and potentially dangerous.
- Large Waves: Seas of 3 to 5 feet can overwhelm small boats, causing them to roll, pitch, and take on water.
- Reduced Visibility: High winds and precipitation can reduce visibility, making it harder to spot other vessels or hazards.
- Storms: Small craft advisories are often associated with approaching storms, which bring additional risks such as lightning, heavy rain, and even tornadoes.
Safety Measures for Small Craft Advisories
If you encounter a small craft advisory, it’s crucial to take the following safety measures:
- Stay Ashore: The safest course of action is to avoid going out on the water entirely.
- Monitor Weather Conditions: Keep an eye on the weather forecast and be aware of any changes or worsening conditions.
- Secure Your Boat: If possible, move your boat to a protected area, such as a marina or harbor.
- Check Equipment: Inspect your boat thoroughly and make sure all safety equipment is in working order.
- Wear a Life Jacket: If you must venture out, always wear a properly fitting life jacket.
Table: Small Craft Advisory Thresholds
| Region | Sustained Winds | Seas |
|---|---|---|
| Northeast | 22-27 knots | 3-5 feet |
| Southeast | 23-28 knots | 3-5 feet |
| Gulf Coast | 22-27 knots | 3-5 feet |
| Pacific Coast | 25-30 knots | 3-5 feet |
| Great Lakes | 24-29 knots | 3-5 feet |
Understanding the “Small Craft” Designation
The term “small craft” refers to any vessel that is less than 65 feet in length and is not capable of withstanding sustained winds of 39 mph (34 knots) or seas of 8 feet. These vessels include:
- Sailboats
- Fishing boats
- Kayaks
- Canoes
- Personal watercraft
- Dinghies
Conclusion
Understanding the meaning of a small craft advisory is essential for ensuring your safety on the water. By taking the necessary precautions, such as staying ashore during adverse conditions and wearing a life jacket when necessary, you can minimize the risks associated with this marine weather warning.

FAQ about “Small Craft Advisory”
What is a Small Craft Advisory?
A Small Craft Advisory (SCA) is a marine warning issued by the National Weather Service (NWS) when winds are forecast to reach or exceed 21 knots (39 km/h; 24 mph) and seas are expected to reach or exceed 3 feet (0.91 m).
What does a Small Craft Advisory mean?
It means that conditions are dangerous for small boats, such as sailboats, rowboats, canoes, and kayaks.
Why is a Small Craft Advisory important?
SCAs are important because they warn mariners of hazardous conditions that could lead to capsizing, sinking, or other accidents.
What should I do if I see a Small Craft Advisory?
If you are planning to go boating, it is important to check the marine forecast for any advisories or warnings. If a SCA is in effect, it is best to postpone your trip until conditions improve.
What is the difference between a Small Craft Advisory and a Gale Warning?
A Gale Warning is issued when winds are forecast to reach or exceed 34 knots (63 km/h; 39 mph). The conditions during a Gale Warning are more dangerous than during a SCA, and it is strongly recommended to avoid going boating.
What is the difference between a Small Craft Advisory and a Storm Warning?
A Storm Warning is issued when winds are forecast to reach or exceed 55 knots (102 km/h; 63 mph). The conditions during a Storm Warning are extremely dangerous, and it is crucial to stay off the water.
How long does a Small Craft Advisory last?
A SCA typically lasts for 12-24 hours, but it can be longer or shorter depending on the weather conditions.
Where can I get more information about Small Craft Advisories?
You can get more information about SCAs from the National Weather Service website, at weather.gov.
What if I am caught in a Small Craft Advisory?
If you are caught in a SCA, it is important to seek shelter immediately. The best place to do this is in a harbor or marina. If you are unable to reach shelter, it is important to remain calm and wait for the winds to subside.
