Forecast tables
  • The hours in the time column are in 24hour format in greek local time.
  • All parameters in the forecast table (ie, temperature, humidity, wind direction and wind intensity) as well as sky conditions (CLEAR, CLOUDY) correspond to the specified time. But the phenomena (ie rain, storm and snow), because they are cumulative figures, refer to the previous 6 hours until the stated time.
About Hours
The forecasts at the time they are published in our hub refer to the next 72 hours divided into 6-hour intervals with the old ones to be removed from the tables.

Forecasts are updated twice a day: Around 9:30 in the morning and 10 in the evening:

The hours for which we provide forecast are:

  • In the Spring and Summer (summer time) : 03:00 , 09:00, 15:00, 21:00
  • Autumn and Winter (winter time)) : 02:00, 08:00, 14:00, 20:00
Hour Symbols
02:00 14:00 Note: For optimal visual understanding, the hours corresponding to morning and noon are light grey, whereas the hours corresponding to the afternoon and night are dark grey.
03:00 15:00
20:00 08:00 All times are in Greek local time.
21:00 09:00
Temperature
Temperature is always in degrees Celcius (°C). To convert it to Fahrenheit click here.
  When the temperature is less than or equal to -13 ° C the corresponding square gets this color
  When the temperature is greater than or equal to -12 ° C and less than or equal to -6 ° C the corresponding square gets this color
  When the temperature is greater than or equal to -5 ° C and less than or equal to 3 ° C the corresponding square gets this color
  When the temperature is greater than or equal to 37 ° C and less than or equal to 39 ° C the corresponding square gets this color
  When the temperature is greater than or equal to 40 ° C the corresponding square gets this color
Thermal perception & stress
Simply put, thermal perception describes how much hot or cold the human feels in a given environment. It is determined by factors that can be broadly divided into environmental (temperature, humidity, wind, radiation) and personal (activity or resting, clothing). For its quantification, our site has adopted the implementation of the human-biometeorological RayMan model, developed by Matzarakis et al. (2007, 2010) at the Human-Biometeorology Research Centre of the German Weather Service and at the University of Freiburg. Specifically, thermal perception is determined using the index of the Physiologically Equivalent Temperature (PET), which also allows for evaluating human thermal stress by applying the following rules:
Perception Stress PET (°C)
Hot Heat – Strong > +35
Very hot Heat – Very strong > +41
Extremely hot Heat – Extreme > +46
Cold Cold – Strong < +8
Very cold Cold – Very strong < +4
Extremely cold Cold – Extreme < -1
Humidity
the moisture is measured as a percentage (%)
Pressure
The pressure appears only in sea areas and is measured in millibars (mb)
Wind - Address
wind coming from the east
άwind coming from the north
wind coming from northeast
wind coming from the northwest
wind coming from the west
wind coming from the south
wind coming from south-east
wind coming from the southwest
Wind - Intensity in terrestrial areas Wind - Intensity in marine areas
Calm
Wind intensity from 1 to 2 beauforts
Wind intensity from 0 to 2 beauforts
wind intensity 3 and 4 beaufort
wind intensity 3 and 4 beaufort
wind intensity 5 and 6 beaufort
wind intensity 5 and 6 beaufort
wind intensity 7 and 8 beaufort
wind intensity 7 and 8 beaufort
wind pressure greater than 8 beaufort
Wind intensity from 9 Beaufort and above
Wind gusts in terrestrial areas. The bursts are calculated when the intensity is greater than 5 beauforts
 
when the wind intensity is equal to or greater than 7 and less than or equal to 8 Beaufort the square gets this color
Conditions suitable for the creation of smog mist
 
when the wind is equal to or greater than 9 beauforts, the corresponding square gets this color
