Weather is a key factor for successful and safe sailing. Yachting Course for Everyone often receives questions such as: "How can I tell if it's safe to go to sea?", "What do the terms 'cyclone' or 'anticyclone' mean?". In this yachting school section, we will clarify the basic meteorological concepts that will help you feel confident on board.
What are the main meteorological phenomena a sailor should know?
Wind and the Beaufort Scale
Wind is the main engine of a sailing yacht, but it can also be the cause of trouble. The wind strength is measured in knots or on the Beaufort scale, which divides wind into 12 categories, from calm to hurricane. For example:
- 1–3 points: light breeze, ideal for training.
- 4–6 points: moderate and strong wind, suitable for crews of varying skill levels.
- 7 and above: stormy conditions, which are best avoided.
Understanding wind strength will help you prepare and correctly trim the sails through yachting courses. If the wind increases, it is important to reduce the sail area (reefing) to maintain control of the yacht.
Cyclones and Anticyclones
Cyclones and anticyclones are areas of differing atmospheric pressure that determine weather patterns. Learn more from a charter agency.
- Cyclone: a low-pressure area. It most often brings cloudiness, precipitation, and gusty winds. Cyclones can be dangerous, especially if their movement intersects with your route.
- Anticyclone: a high-pressure area. It usually accompanies clear weather and light winds, which is ideal for calm passages.
Clouds as Weather Indicators
Even without access to a weather forecast, you can learn much just by looking at the sky:
- Cumulus clouds: indicate stable weather, especially in the morning.
- Cirrus clouds: may signal the approach of a cyclone or changes in the weather.
- Cumulonimbus clouds: signal sharp changes in wind, rain, and thunderstorms. If you see such clouds, it’s better to stay in the marina.
Wind Direction
Wind direction is another important aspect. It is measured in degrees relative to north (0° indicates north wind, 90°—east, 180°—south, and so on) or described by cardinal directions (e.g., "northerly wind," "westerly wind"). To determine the wind direction, you can use instruments on the yacht or observe flags, waves, and even the movement of smoke.
Why is this important?
Understanding these meteorological phenomena helps predict weather changes, plan routes, and avoid trouble at sea. Training through the Inshore Skipper Sail course and knowing the basics of meteorology and how to avoid seasickness will make your sailing safe and comfortable.
How to get an accurate weather forecast for yachting?
A weather forecast is your primary tool for safe sailing. Without it, even experienced sailors can find themselves in difficult situations. But how do you effectively use the available forecasts?
Popular Apps and Websites for Forecasts
Today, there are many tools that help monitor the weather in real time. Here are some of the most popular:
- Windy: a visualized forecast showing wind direction and speed, precipitation, and temperature. It's one of the best tools for sailors, thanks to its clarity.
- Windfinder: provides detailed forecasts of wind and waves. Convenient for planning passages.
- Windguru: designed specifically for water sports, including yachting. Suitable for checking wind, waves, and atmospheric pressure.
- Poseidon: especially useful for those sailing in Greek waters. Provides accurate data on sea conditions.

How to Read Forecasts
To make the most of the forecasts, it is important to understand which data is most critical:
- Wind speed: measured in knots. For example, a speed of 15–20 knots is considered comfortable for sailing.
- Wind direction: indicates where the wind is blowing from. It's important to know how it will affect your route.
- Wave height: critically important for open sea. Waves over 2 meters can be dangerous for small vessels.
- Precipitation: rain is not always a problem, but thunderstorms can be dangerous.
Why it's important to use multiple sources
Weather forecasts are always assumptions based on models. To obtain the most accurate data:
- Compare forecasts from multiple sources.
- Use local weather stations for clarification.
- Check for updates to forecasts, especially before heading out to sea.
Recommendations for choosing tools
- For planning a weekly route, Windy is suitable as it visually shows long-term forecasts.
- Windfinder is better for short-term forecasts.
- In areas with changeable weather, such as the Mediterranean Sea, local resources like Poseidon can be particularly useful.
Using modern tools and understanding forecasts will help you avoid unexpected surprises at sea and make your journey comfortable and safe.
How does weather affect yacht management?
Weather has a direct impact on all aspects of yacht management. It determines what decisions the skipper needs to make to maintain control of the vessel and ensure the crew's safety. Let's look at the main weather conditions and their effects.
Wind
Wind is the foundation of sailing. However, its changes may require quick actions:
- Increasing wind: If the wind strengthens, it's necessary to reduce the sail area (for example, reef the main sail or reduce the genoa). This will reduce the load on the mast and make yacht handling more stable.
- Weak wind: When the wind weakens, it's important to properly adjust the sails to maintain their effectiveness. In the absence of wind, engine usage may be required.
Waves
Waves can significantly complicate yacht management:
- Small waves: Easily overcome and usually do not require special actions.
- High waves: When crossing large waves, it's important to adjust your course to minimize the yacht's roll. It is recommended to approach the wave at an angle rather than head straight into it.
Precipitation and visibility
Rain, fog, and other precipitation can hinder visibility:
- Use navigation instruments such as radars and GPS.
- Make sure all crew members are dressed in waterproof clothing.
Temperature and weather conditions
Weather changes, such as sudden cooling or heat, affect the crew's physical condition. Ensure that warm clothing and sun protection supplies are on board.
How does weather differ in various yachting regions?
Weather conditions vary significantly depending on the sailing region. Understanding the specifics of each region will help you prepare properly.
Mediterranean Sea
- Mistral: A cold northern wind that can reach speeds of 50 knots. Most commonly encountered in the winter and spring months.
- Sirocco: A warm southern wind from the Sahara that brings heat and dust.
- Tramontana: A strong wind characteristic of the northwestern part of the Mediterranean Sea.
Caribbean
- Hurricane season: The period from June to November, when the risk of hurricanes is highest. Plan routes for other months.
- Trade winds: Persistent winds blowing from the east, creating ideal sailing conditions in winter.
Baltic Sea
- Cold winds: In winter and spring, weather conditions can be harsh, so the crew will need extra insulation.
- Frequent fog: Limits visibility, especially in transitional seasons. Use radars and signal lights.
Understanding the specifics of each region will help you prepare properly, and yacht rental will help you choose the right yacht for your journey.
How to plan a route considering weather?
Planning a route with regard to the weather forecast is essential for a safe and successful journey. Here are the key points to consider:
When is the best time to go to sea?
- Carefully study the weather forecast for the next 24–48 hours.
- Look for "weather windows" — periods when the wind and waves will be suitable for going to sea.
- Avoid planning transitions during expected storms or strong winds.
How to choose a parking place?
- Prefer protected bays or marinas, especially if sharp weather changes are predicted.
- Ensure that the chosen place is safe for anchoring: the bottom should provide reliable anchor grip.
- Plan a backup option in case of weather changes.
What to do if the weather worsens?
- Immediately assess the possibility of taking shelter in the nearest marina or protected bay. If shelter is not available, change course to minimize the impact of waves and wind. Ensure the crew's safety by distributing life jackets and clarify the location of the nearest points of assistance. Learn tips from experienced travelers.
The weather at sea can be both your best friend and a serious challenge. But if you learn to understand its characteristics, use forecasts, and prepare properly, no surprises can mar your journey. May every outing to sea be not only safe for you but also unforgettably pleasant!
