Live lightning and thunderstorms · electrical activity map

Explore recent lightning detections from the Blitzortung network in Greece, Europe and other covered regions. Pan, zoom or use fullscreen. The provider’s legend explains how colours distinguish the age of detections.

Lightning detections and rain radar are different observations: compare them to follow a storm. Network coverage and accuracy vary by region; no detections does not mean no danger. This map is not a warning or protection service.

How to follow the weather now

Greece and Europe satellite, rain radar and lightning

The weather is easier to understand when you compare the wider cloud picture with observations on the ground. Start with the Greece and Europe weather satellite to explore cloud position and movement, then open the rain radar for available precipitation imagery. The same page links to lightning tools. Comparing these views helps you follow a rainy day or a thunderstorm while keeping the time of each image in view.

Weather stations and webcams in Athens and northern Attica

For local conditions, explore the Agios Stefanos weather station in Attica and the Athens and northern Attica weather webcams. Temperature, wind and rainfall readings complement the camera view, helping you compare changes in cloud cover or visibility with station observations. The station timelapse brings together the changing view through the day, while the station climate archive provides a route to earlier observations and the area’s climate records.

From current weather to your local forecast

Observations describe current conditions; forecasts examine the hours and days ahead. After checking stations, webcams and satellite imagery, continue to your local weather forecast. The interactive meteogram helps you compare temperature, precipitation and wind over time. Ensemble charts let you explore the available scenarios for 850 hPa temperature and precipitation, keeping a single forecast in the context of the wider range of outcomes.

Separate tools for earthquakes, volcanoes and cyclones

The natural events section connects you to earthquakes in Greece, the world earthquake map, volcanoes and eruption history and hurricanes, typhoons and medicanes. These tools cover different kinds of information: recent earthquake records, historical volcano data and available cyclone tracks. Follow the relevant tool for its sources, time filters and explanations.

What comes next? Your local weather forecast

Open the 14-day forecast and compare the coming hours in the meteogram. Ensembles of 850 hPa temperature and precipitation show the spread of available scenarios.
