Smoke from four Greek wildfires drifts over Corinthian Gulf and Peloponnese, tracked by AtmoHub
Smoke from four active wildfires in Greece is drifting across the Corinthian Gulf and covering eastern Peloponnese, with the pilot monitoring service AtmoHub tracking the plumes via satellite.
Active wildfires
Four significant forest fires were burning across Greece on 1 August 2026, with fronts in Porto Germeno (West Attica), Viotia, Skaloma Fokidas, and Aigialeia. The fires produced large quantities of smoke that were visible in satellite imagery and prompted continuous monitoring by the national atmospheric composition service. No containment figures or evacuation orders were reported in the initial bulletins, but the simultaneous outbreaks stretched across central and southern Greece, from the northern coast of the Corinthian Gulf to the northern Peloponnese.
Smoke dispersion forecast
Prevailing meteorological conditions pushed the smoke from the Porto Germeno fire toward the southwest. The plume extended over the Corinthian Gulf and had already covered a large portion of eastern Peloponnese by the time the simulations were released. Meanwhile, smoke from the Aigialeia and Fokida fires moved mainly westward, following the general wind flow. The forecasts indicated that the smoke would continue along these trajectories, potentially affecting air quality in downwind communities.
Monitoring by AtmoHub
The dispersion patterns were calculated by AtmoHub, a pilot information hub for atmospheric composition in Greece. The service relies on satellite-based emission estimates and numerical smoke transport models to produce near-real-time simulations. On 1 August, AtmoHub released a video showing the projected movement of smoke plumes from all four active fires, using data from satellite observations and dispersion modelling. The simulations are intended to help authorities and the public anticipate where smoke concentrations may rise.
Affected areas
The area most directly under the smoke plume from Porto Germeno was eastern Peloponnese, across the Corinthian Gulf. The simulation showed the cloud blanketing a wide swath of the region. To the west, communities downwind of the Aigialeia and Fokida fires faced drifting smoke moving out over the Ionian side of the peninsula. No ground-level air quality measurements were included in the initial reports, but the visual extent of the plumes suggested reduced visibility and potential respiratory irritants for residents in the path of the smoke.
