​Transition to Mid-Autumn Meteorological Patterns Across Greek FIRs

Transitioning from late September into early October, regional weather patterns shift toward cooler, classic mid-autumn conditions across the Greek mainland and Aegean basin. While Visual Flight Rules (VFR) remain widely dominant across major sectors, early signs of seasonal frontal systems begin to brush northern and western approach corridors, bringing localized cloud buildups and refreshing maritime airflows. Flight dispatchers and ground crews should note the pronounced drop in ambient temperatures and prepare for increased atmospheric variability and early-morning condensation risks.



Athens International Airport "Eleftherios Venizelos" (LGAV)

Daytime highs easing comfortably between 22°C and 25°C, with crisp overnight lows settling down to 14°C–16°C under predominantly clear skies. Northerly winds remain light to moderate.


Operational Impact: Exceptional visibility persists, and density altitude constraints are now fully alleviated. The cooler ambient temperatures optimize engine and wing performance for all heavy departures, though early morning ground crews should monitor for localized radiation mist in low-lying apron sectors.

Thessaloniki International Airport "Makedonia" (LGTS)

Daytime temperatures ranging from 20°C to 23°C, dropping to cooler, crisp overnight minimums of 10°C–13°C. Stable atmospheric setup with light, variable surface winds and occasional early-morning valley fog.


Operational Impact: Highly favorable conditions for precision ILS approaches and standard vectoring. Flight crews should review low-visibility procedures during dawn hours when early autumn thermal inversions temporarily restrict surface visibility along northern approach vectors.

Heraklion International Airport "Nikos Kazantzakis" (LGIR)

Moderate daytime temperatures between 23°C and 26°C, cushioned by steady northerly breezes averaging 10–14 knots. Overnight lows settle near 16°C–18°C.


Operational Impact: Continued maritime airflow keeps runway asphalt temperatures well-regulated. While overall operational stability remains high, dispatchers should watch for developing mid-level cloud decks and passing showers associated with early-october Cretan sea moisture influxes.

Rhodes International Airport "Diagoras" (LGRP)

Pleasant transitional pattern with maximum temperatures reaching 24°C to 27°C, easing to comfortable night lows around 17°C–20°C. Consistent north-westerly airflow..

Operational Impact: Unrestricted visual approaches across the Dodecanese corridor. Ground operations can operate under ideal thermal comfort levels as peak summer solar radiation subsides, maintaining excellent efficiency across all apron turnarounds.
