What can be seen?

weather condition

If possible, we calculate from the measurements of the weather stations a weather symbol, which shows the current weather condition.

temperature

The air temperature is measured at a height of 2 metres above the ground. The temperature sensor is protected from sunlight and some are also ventilated in order to measure the most accurate values possible without heat radiation. We calculate the minimum and maximum air temperature over the whole day.

air pressure

The air pressure is reduced to sea level so that the values of the stations at different altitudes are comparable. Regions with low air pressure usually get changeable weather with wind, rain or snow. In regions with high air pressure, dry weather and sunshine usually dominate. The average air pressure is 1013.25 hPa.

humidity

The humidity shows how much gaseous water is in the air, relative to the maximum possible water vapor content (depending on the air temperature), i.e. the value at which the air reaches the saturation point. At 100% humidity, the air is saturated, dew, fog or clouds form.

dew point

The dew point is the temperature to which the air can cool down to reach 100% humidity. When the dew point is reached, fog or clouds form.

sun

We accumulate the measured duration of sunshine over different periods of time.

precipitation

This measurement shows the amount of precipitation that has fallen. It can be rain, sleet, snow, graupel or hail. Precipitation in solid form (e.g. snow) is indicated here in melted form in millimetres, provided the weather station has a heater.

fresh snow

The amount of new snow in the last 24 hours is usually measured once a day, often in the morning at 07:00.

snow depth

Depending on availability, we show the value at 07:00 or an average of the period as the snow depth. It is the thickness of the lying snow cover. Fresh snow usually increases the snow cover. Heat, solar radiation or rain reduce the snow depth.

wind direction

The wind direction is the direction from which the wind is blowing. The wind arrow points in the direction the wind is blowing. A circle means that there is no clear prevailing wind direction.

wind speed

The wind speed is usually an average value over 10 minutes. The wind is measured at most stations 10 meters above ground and in an open field without obstacles.

gusts of wind

The gust value is the highest, briefly measured wind speed of the respective period. One speaks of a storm from 75 km/h.

The map shows actually measured weather parameters - current measurements or accumulated over hours. The measuring stations report different measured variables at different time intervals. In addition, the measuring networks are not equally dense in all countries around the world. For this reason, the map of measurements, which is available for all countries in the world, is not always filled in the same way in terms of time and space.

With a click on the measurement of the respective location, you get to the detailed measurement overview of the weather station.

Whenever possible, the measurements correspond to international standards. Cumulative periods are only calculated if there are enough individual measurements. Since a lot of measurement data is collected and processed automatically, incorrect values cannot be ruled out.
