Tomorrow, Wednesday, 26 August 2026, will see continued hot and mostly clear conditions across Greece, according to the Hellenic National Meteorological Service (EMY). While minor regional variations are expected, the intense heat is set to persist nationwide, with temperatures peaking at 39°C in parts of southern mainland Greece.
General Conditions
Most areas will experience predominantly clear skies. However, isolated cloud formations are forecast—particularly over mountainous regions—along with brief showers and scattered thunderstorms. These are most likely in Macedonia, especially across the central and eastern highlands, mainly during midday and afternoon hours. A low probability of similar activity also exists over other inland mountainous zones.
Wind Patterns
Winds will remain generally light and variable across much of the country. Over the seas, westerly to northwesterly winds of 3–5 Beaufort are expected, locally reaching 6 Beaufort—especially in the Ionian Sea from midday onward.
Temperature Outlook
Temperatures will remain largely unchanged from today’s levels. Mainland areas will see highs between 36°C and 38°C, with southern regions possibly hitting 39°C. In the islands, mercury will range from 34°C to 36°C.
Attica
Clear skies dominate. Winds will be variable at 3–4 Beaufort. Temperatures will range from 26°C to 38°C—or 39°C in some southern suburbs.
Thessaloniki & Macedonia
Generally clear, though brief cloud cover may appear during the afternoon. In central and eastern Macedonia, especially in higher elevations, isolated thunderstorms and short-lived rain showers are possible around midday and into the evening. Winds will be variable at 2–4 Beaufort, shifting to southerly in the afternoon at similar intensity. Temperatures will climb from 23°C to 36°C—with localized peaks of 37°C–38°C in central Macedonia.
