Mid-autumn meteorological patterns solidify across Hellenic FIRs from 8 to 14 November 2026. Eastward-shifting high-pressure ridges allow weak fronts and localized troughs to cross the region, bringing cooler temperatures, variable cloud cover, and increasing wind shear along island channels. Operational updates cover key gateways: single-runway maintenance at Athens (LGAV), morning sea fog at Thessaloniki (SKG), crosswinds at Heraklion (LGIR), and clear IFR corridors at Rhod

A late-autumn low-pressure system moving across the Aegean basin and Ionian sectors brings heightened humidity, lowering cloud ceilings, and scattered rain bands to Greek FIRs early in the week. Operational conditions transition from temporary VFR disruptions to clearing, partly sunny skies heading into Thursday and Friday.

A dominant high-pressure ridge brings stable VFR clarity and mild autumn temperatures across Greek FIRs early in the week. Operational conditions remain favorable across major hub corridors before a Mediterranean low-pressure system introduces increasing cloud cover, localized ceiling drops, and scattered rain showers mid-to-late week. Read the operational flight briefing for Athens (LGAV), Thessaloniki (LGSK), Heraklion (LGIR), and Rhodes (LGRP).

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).

Aviation Weather (04–10 Oct 2026): Mid-autumn brings cooler conditions across Greek FIRs with VFR dominant. LGAV: 22–25°C, nights 14–16°C; density altitude constraints cleared. LGTS: 20–23°C, morning fog risks. LGIR: 23–26°C, stable north breezes (10–14 kt). LGRP: 24–27°C transitional comfort. Northern sectors experience early-morning cloud buildups.

As September draws to a close, stable high-pressure patterns continue to dominate Greek FIRs, ensuring pristine VFR conditions across major hubs. While Athens (LGAV) and Rhodes (LGRP) maintain comfortable late-summer warmth with favorable density altitudes, northern and island sectors like Thessaloniki (LGTS) and Heraklion (LGIR) experience refreshing seasonal cooling and steadily easing Meltemi breezes, delivering optimal operational stability for all domestic and long-haul

High-pressure stability continues across Aegean and mainland FIRs for the week of 30 August – 5 September 2026, sustaining pristine VFR conditions and easing Meltemi winds. Athens (LGAV) and Rhodes (LGRP) peak at 31°C–35°C with high density altitudes requiring load checks. Thessaloniki (LGTS) cools slightly to 28°C–32°C with stable ILS approaches. Heraklion (LGIR) maintains 29°C–32°C highs, regulated by steady 15–18 knot maritime breezes.

Stable high pressure anchors VFR conditions across Greek FIRs for 6–12 September 2026. As seasonal Meltemi winds gradually ease across the Aegean, dispatchers can expect excellent visibility and minimal cloud cover. Temperatures range from 27°C–33°C across LGAV, LGTS, LGIR, and LGRP, offering slight relief from late-summer heat and improving density altitude margins for heavy departures.

High-pressure stability continues across Aegean and mainland FIRs for the week of 30 August – 5 September 2026, sustaining pristine VFR conditions and easing Meltemi winds. Athens (LGAV) and Rhodes (LGRP) peak at 31°C–35°C with high density altitudes requiring load checks. Thessaloniki (LGTS) cools slightly to 28°C–32°C with stable ILS approaches. Heraklion (LGIR) maintains 29°C–32°C highs, regulated by steady 15–18 knot maritime breezes.

High-pressure ridging continues across the Aegean and mainland FIRs for the week of 23–29 August 2026, delivering nationwide VFR conditions, high heat, and steady Meltemi breezes. Athens (LGAV) and Rhodes (LGRP) will reach highs of 33°C–36°C with north-northwesterly winds. Thessaloniki (LGTS) sees temperatures up to 34°C with slight mid-week cloudiness. Heraklion (LGIR) benefits from maritime moderation, with steady 15–20 knot breezes capping highs at 29°C–33°C.

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 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.

Persistent high pressure maintains highly predictable mid-summer operations across Greece’s major airports, with clear skies and excellent visibility supporting largely disruption-free conditions. Rising mainland temperatures bring increased density-altitude and aircraft performance considerations, particularly at Thessaloniki, while steady northerly winds continue to shape operations across Crete and the Southeast Aegean. Our outlook covers 12/07 to 18/07.

A dominant high-pressure system supports highly stable operations across Greece’s major airports, with clear skies and excellent visibility limiting weather-related disruption. Rising temperatures, particularly in Athens and Thessaloniki, increase heat and aircraft performance considerations, while steady northerly winds shape predictable conditions across the Aegean. Our outlook covers Athens, Thessaloniki, Heraklion and Rhodes from 05/07 to 11/07.

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.
