Operational aviation weather overview for Greek FIRs covering 09 – 15 August 2026. Peak-summer thermal buildup across the mainland drives elevated density altitude considerations at Athens (LGAV) and Thessaloniki (LGTS). Simultaneously, active Meltemi regimes bring steady northerly breezes and predictable crosswind vectors to Aegean island gateways at Heraklion (LGIR) and Rhodes (LGRP), maintaining ideal VFR operational conditions FIR-wide.

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.
