**Aviation Weather Overview (09–15 August 2026):** Greece enters the peak of the August travel season with stable high-pressure conditions across the Athinai FIR. Clear skies and VFR conditions prevail across all major hubs. Thessaloniki (LGTS) faces the highest thermal peaks up to 37°C with density altitude considerations for heavy departures, while Athens (LGAV) holds between 29°C and 35°C. Maritime gateways in Heraklion (LGIR) and Rhodes (LGRP) enjoy moderated temperatures

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.

An intense heat dome brings severe thermal loading to Greece’s mainland airports, increasing density-altitude and aircraft performance considerations in Athens and Thessaloniki. Meanwhile, an intensified Meltemi drives stronger northerly winds across the Aegean, with turbulence and crosswind factors more relevant at island gateways. Our outlook covers Athens, Thessaloniki, Heraklion and Rhodes from 19/07 to 25/07.

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.
