You can use the Weather Map on MarineRadar to view weather conditions directly alongside live vessel positions. Open the MarineRadar map, tap the Layers button, turn on the weather overlays, and select the weather layer you want to examine. You can then compare a ship’s position and movement with wind, temperature, cloud cover, and rain shown on the map.
This is especially useful when a ship slows down, changes course, takes a longer route, or appears to wait at sea. Instead of looking at ship movement alone, you can use weather information to understand the conditions around the vessel.
MarineRadar’s Weather Map is therefore a useful addition to its live AIS vessel-tracking tools, whether you are a ship enthusiast, researcher, logistics professional, or simply curious about what is happening at sea.
What Is the MarineRadar Weather Map?
The MarineRadar Weather Map is a map layer that overlays weather information directly onto the vessel-tracking map.
Previously, when watching a ship, you might only see its current position, speed, direction, destination, ETA, and route.
MarineRadar’s current Weather Map feature provides layers for:
- Wind
- Temperature
- Cloud cover
- Rain
MarineRadar’s weather information can also help users understand broader conditions such as storms and changing ocean weather. This makes the map more useful because you can view the ship and the surrounding weather at the same time.
Why Add Weather to a Ship Tracking Map?
A ship does not move through an empty blue space. It travels through changing environmental conditions. Wind, rain, storms, and other weather conditions can influence how a vessel operates.
For example, imagine you are tracking a container ship.
You noticed that it was traveling at 15 knots yesterday but is now moving much more slowly. Looking only at the vessel data, you know its speed has changed.
Now switch on the weather map. You may see poor weather around the vessel’s route. This does not prove that the weather caused the change in speed, but it provides important context for further investigation.
Weather can be associated with:
- Reduced vessel speed
- Course changes
- Longer routes
- Delayed arrivals
- Temporary waiting
- Changes in voyage planning
MarineRadar’s existing ship-tracking features let users examine vessel speed, course, destination, ETA, and route history, while the Weather Map adds environmental context to that information.
How to Turn On the Weather Map on MarineRadar
Using the weather map is simple.
Step 1: Open MarineRadar.
Open the MarineRadar website or mobile app and go to the map. The live map displays vessels and their current positions.
Step 2: Open the Layers Menu
Look for the Layers button on the map. Tap it to see the available map and weather options.
Step 3: Turn On Weather Overlays
Enable the weather overlays. The weather information will appear directly over the map.
MarineRadar’s published feature instructions describe this process as
- Tap the Layers button.
- Turn on weather overlays.
- Pick the weather layer you want.
- View the live weather on the map.
Step 4: Select a Weather Layer
Choose the weather information you want to examine. Depending on the available layers, you can check:
- Wind
- Temperature
- Cloud cover
- Rain
Step 5: Find the Vessel
Search for a ship or zoom into an area where vessels are traveling.
MarineRadar supports vessel searches using information such as the ship name, IMO number, and MMSI number.
Step 6: Compare the Ship With the Weather
Look at the ship’s position and movement alongside the weather layer.
Ask simple questions:
- Is the ship moving toward bad weather?
- Has its speed changed?
- Has its course changed?
- Is the vessel moving around a weather system?
- Has its ETA changed?
This comparison is where the weather map becomes especially useful
Understanding the Main Weather Layers
Not every weather layer tells you the same story. Each one provides a different clue.
1. Wind
Wind is one of the most important weather conditions to watch when studying vessel movement.
Strong winds can influence:
- Vessel speed
- Fuel consumption
- Heading
- Route decisions
- Sailing conditions
MarineRadar’s weather information lets users view wind conditions while tracking ships.
If a ship suddenly slows while moving through an area of strong winds, the weather may provide useful context.
However, do not automatically assume that wind caused the slowdown. Other factors, such as traffic, port instructions, mechanical problems, or voyage planning, can also affect speed.
2. Temperature
Temperature provides additional information about the environment around a vessel. On MarineRadar, temperature is included among the weather map’s current weather layers.
Temperature is more useful when combined with other information than when viewed alone.
For example, you could compare temperature conditions with:
- Cloud cover
- Rain
- Wind
- Vessel speed
- Route direction
This creates a more complete picture of the environment around the ship.
3. Cloud Cover
Cloud cover helps you see how weather conditions are distributed around a shipping route. A ship traveling toward an area with significant cloud activity may be approaching a changing weather system.
Cloud information is particularly useful when combined with wind and rain data.
4. Rain
Rain is another weather layer available in MarineRadar’s current Weather Map feature. Rain can be especially relevant when following vessels near ports or during changing weather conditions.
Heavy rainfall can reduce visibility for crews and may occur alongside larger weather systems.
When you see rain around a ship, check the vessel’s:
- Speed
- Course
- Heading
- ETA
- Route
This lets you compare weather conditions with actual vessel movement.
How to Use the Weather Map While Tracking a Ship
The real value comes from combining weather information with vessel information.
Here’s a simple example.
Suppose you are tracking a cargo ship traveling across the ocean.
First, check its position.
Find the ship on the MarineRadar map.
Next, check its speed.
Open the vessel details and see how fast it is moving.
Then, check its course.
Look at the direction in which it is traveling.
Finally, turn on the weather map.
Check the weather around the vessel.
Now you have four useful pieces of information:
- Position + Speed + Direction + Weather
If the vessel changes course near an area of severe weather, you have a possible explanation for the change in course.
MarineRadar specifically recommends comparing weather conditions with vessel routes when investigating slowdowns or course changes.
How Weather Can Change a Ship's Route
Ships do not always follow a perfectly straight line.
A captain or voyage planner may need to adjust a route because of:
- Strong winds
- Storms
- Rough sea conditions
- Port congestion
- Traffic
- Safety considerations
- Other operational restrictions
Weather is therefore one factor that can explain why a ship takes a different path.
For example:
Planned route → Bad weather appears → Vessel changes course → Voyage becomes longer
MarineRadar’s Weather Map can help you visualize the relationship between the weather area and the vessel’s movement.
Using Weather and Route History Together
One of MarineRadar’s useful features is route history and playback. This allows users to examine how a vessel moved over time. MarineRadar’s current platform supports route history and playback to study previous vessel movements.
You can combine this with weather information to perform a simple analysis.
Try this:
- Find a vessel.
- Open its route history.
- Review its previous movement.
- Identify a major course or speed change.
- Return to the map.
- Turn on the Weather Map.
- Examine the weather around that area.
- Compare the two pieces of information.
This can help researchers, students, ship enthusiasts, and logistics teams understand how environmental conditions may have affected a voyage.
How to Use the Weather Map for Open-Ocean Tracking
Weather becomes particularly interesting when following vessels far from land. Coastal ship tracking and deep-ocean tracking can work differently because terrestrial AIS receivers have limited geographic reach.
Satellite AIS helps extend vessel visibility beyond coastal areas. MarineRadar states that it combines terrestrial and satellite AIS for vessel tracking, with satellite coverage particularly important for deep-ocean routes.
When tracking a ship across the open ocean, you can:
- Search for the vessel.
- Open its vessel profile.
- Check its current position.
- Check its speed and direction.
- Turn on the Weather Map.
- Look for weather systems along its route.
- Compare weather with route changes.
- Check the ETA for possible changes.
This makes a long ocean voyage much easier to understand.
Can the Weather Map Explain Why a Ship Slows Down?
This is an important distinction. Suppose a ship slows from 16 knots to 8 knots. At the same time, the weather map shows strong weather conditions nearby. It is reasonable to consider weather as a possible factor.
But the slowdown could also result from:
- Traffic
- Port instructions
- Engine problems
- Navigation decisions
- Waiting for another vessel
- Speed restrictions
- Other operational reasons
Therefore, use the weather map together with vessel details rather than making conclusions from weather alone.
Weather Map for Port and Coastal Monitoring
The weather map is not only useful in the middle of the ocean. It can also help when watching ships near ports.
Ports can become busy when many vessels arrive at the same time. Weather conditions may add another challenge to vessel operations.
For example, you can monitor:
- Ships approaching the port
- Ships waiting offshore
- Vessel speeds
- Weather around the harbor
- Rain systems
- Wind conditions
- Changes in ETA
MarineRadar’s live map and vessel information can be used to understand port activity, while weather layers add environmental context.
Weather Map and Global Shipping
Weather tracking matters because ships carry a huge share of international trade.
According to UN Trade and Development (UNCTAD), over 80% of world merchandise trade by volume is carried by sea. That means weather conditions at sea can affect more than just individual vessels.
They can influence:
- Shipping schedules
- Port arrivals
- Cargo deliveries
- Fuel use
- Voyage planning
- Supply chains
UNCTAD also highlights how disruptions affecting maritime routes can extend shipping distances, increase costs, and place pressure on global supply chains.
Who Can Benefit From MarineRadar's Weather Map?
The feature can be useful to several types of users.
Ship Enthusiasts

Weather Map vs. a Normal Weather App
A normal weather application usually focuses on your location, cities, regions, or general weather forecasts.
MarineRadar’s Weather Map has a distinct advantage: it displays weather and vessel tracking together.
Instead of switching between two applications, you can look at Ship → Route → Weather → Movement on the same map. That makes it easier to connect the information.
Best Practices for Using the MarineRadar Weather Map
For better results, follow these simple habits:
1. Check More Than One Weather Layer
Wind alone may not tell the complete story. Compare it with rain, cloud cover, and temperature where appropriate.
2. Look at the Vessel’s Speed
A weather map becomes more useful when you compare conditions with actual vessel movement.
3. Watch the Course
A sudden turn can be more informative than a small change in speed.
4. Check the ETA.
If the route changes, see whether the estimated arrival time also changes.
5. Use Route History
Look at previous movements to understand whether a route change is unusual.
6. Don’t Assume the Cause
Weather may explain a change in movement, but it is not always the reason.
7. Check Data Freshness
AIS and weather information can have different update cycles. Offshore vessel positions may not update continuously, so a displayed position should be interpreted in light of its timestamp and data availability.
MarineRadar Weather Map in 2026
The Weather Map is part of MarineRadar’s continued expansion beyond basic vessel-location tracking.
Recent MarineRadar app updates have added the ability to view real-time weather conditions via the new Weather Map, along with other map-related improvements. The iOS version history also lists exploration of Marine Protected Areas as a recent map feature.
Meanwhile, the Android listing describes MarineRadar as a vessel-tracking app covering ships, yachts, and containers, with features including live tracking, vessel information, port arrivals and departures, advanced search, fleet monitoring, and route history/playback.
Together, these features make the map more than a simple collection of moving ship icons. Users can combine vessel information, historical movement, and environmental context in one place.
Conclusion
The easiest way to use the Weather Map on MarineRadar is to think of it as another layer of information around your ship.
Start by opening the map, tapping Layers, enabling the weather overlays, and selecting the weather information you want to see. Then search for a vessel and compare its position, speed, course, and route with the surrounding weather.
MarineRadar currently provides weather layers, including wind, temperature, cloud cover, and rain. The biggest advantage is that you don’t have to look at ship movement and weather separately.
You can use both together to better understand why a vessel may slow down, change direction, wait, or take a different route. For deeper analysis, combine the weather map with MarineRadar’s vessel details and route history.
