As October advances, Greek FIRs transition into active mid-autumn weather patterns. A passing Aegean trough brings scattered rain, convective activity, and lowering ceilings early in the week before VFR conditions stabilize. Read the latest operational flight briefing for Athens (LGAV), Thessaloniki (LGTS), Heraklion (LGIR), and Rhodes (LGRP).

Operational aviation weather overview for Greek FIRs covering 16 – 22 August 2026. Peak late-summer high-pressure dominance across mainland FIRs keeps daytime temperatures elevated, requiring continued density altitude monitoring at Athens (LGAV) and Thessaloniki (LGTS). Simultaneously, active Meltemi wind regimes deliver steady northerly flow across Aegean island gateways at Heraklion (LGIR) and Rhodes (LGRP), ensuring clear skies and predictable VFR operational conditions.

Operational aviation weather overview for Greek FIRs covering 02 – 08 August 2026. Peak-summer thermal buildup across the mainland drives elevated density altitude considerations at Athens (LGAV) and Thessaloniki (LGTS). Meanwhile, active Meltemi regimes bring sustained northerly winds and predictable crosswind vectors to Aegean island hubs at Heraklion (LGIR) and Rhodes (LGRP), maintaining ideal VFR conditions.

Terminal aviation weather outlook for Greece’s primary international gateways (LGAV, LGTS, LGIR, LGRP) covering 26 July to 01 August 2026. Discover operational impacts, temperature forecasts, density altitude alerts, and Aegean Meltemi wind patterns shaping flight operations across the FIR this week.

Predominantly stable summer weather supports operations across Greece’s major airports, with high temperatures and generally good visibility limiting widespread disruption risks. Stronger regional winds, particularly across the Aegean, remain the key operational variable, potentially affecting runway configurations, approaches and ground handling. Our seven-day outlook assesses conditions at Athens, Thessaloniki, Heraklion and Rhodes from 28/06 to 04/07.
