Progression into Mid-September Meteorological Patterns Across Greek FIRs

Advancing deeper into September, regional weather patterns display stable barometric pressure fields across the Greek mainland and Aegean basins, though slight early-autumn atmospheric transitions begin to introduce refreshing nocturnal temperature drops. Visual Flight Rules (VFR) remain universally favorable across all primary sectors with pristine sky conditions, low humidity, and steadily moderating seasonal Meltemi flows. Flight dispatchers and ground operations teams should monitor subtle evening wind shifts and standard afternoon density altitude variations during peak departure intervals..

Athens International Airport "Eleftherios Venizelos" (LGAV)

Daytime highs peaking between 30°C and 33°C, with overnight lows easing comfortably to 20°C–22°C under clear skies. Northerly breezes remain light to gentle.

Operational Impact: Exceptional visibility and ceiling conditions persist. Afternoon temperature peaks continue to require routine payload and runway performance checks for heavy long-haul departures.

Thessaloniki International Airport "Makedonia" (LGTS)

Highs ranging from 27°C to 30°C, dropping to crisp overnight minimums of 16°C–19°C. Highly stable atmospheric conditions accompanied by light, variable surface winds.

Operational Impact: Optimal conditions for standard vectoring and precision ILS approaches. Pronounced early-autumn nighttime cooling minimizes thermal turbulence along northern approach corridors.

Heraklion International Airport "Nikos Kazantzakis" (LGIR)

Steady daytime temperatures between 28°C and 31°C, balanced by consistent northerly Meltemi breezes averaging 12–15 knots. Overnight lows near 21°C–23°C.

Operational Impact: Continuous maritime airflow maintains regulated runway asphalt temperatures. Afternoon crosswind components remain manageable, ensuring high overall operational reliability.

Rhodes International Airport "Diagoras" (LGRP)

Warm and dry pattern with maximum temperatures reaching 30°C to 33°C, easing to comfortable night minimums around 20°C–22°C. Persistent north-westerly airflow.

Operational Impact: Unrestricted visual approaches across the Dodecanese corridor. Ground crews should maintain standard hydration protocols during peak afternoon turnarounds as late-summer solar intensity remains active.
