With the meltemi winds persisting over the Aegean and temperatures climbing but remaining within seasonal norms, the weather pattern will hold steady through the start of September. The only exceptions will be some local showers in mountainous areas, which are not expected to affect the overall outlook.

In his latest forecast, meteorologist Klearchos Marousakis noted that temperatures will stay within normal seasonal ranges until September 10, with increased rainfall expected from mid-month onward. He stressed that while a slight temperature rise is anticipated next week, it cannot be considered a heatwave.

According to the Open TV forecaster, strong northerly winds will continue in the coming days, reaching up to 7 Beaufort in the Aegean. Afternoon showers are likely in mountainous areas of central and northern Greece. Winds in the central Aegean and the Carpathian Sea may reach gale force, while in Crete, katabatic winds will create warmer and drier conditions, especially in the island’s southern regions.
