Expect summer-like weather over the Holy Spirit long weekend, with mostly clear skies nationwide and temperatures soaring up to 37°C in some regions. This warm spell is expected to persist until at least Monday, though meteorologists emphasize it is not classified as a heatwave.
Meteorologist Thodoris Kolydas noted that elevated temperatures will continue through Monday but warned of unstable weather conditions in the northern areas.

However, those traveling north should pack an umbrella, as meteorologist Klearchos Marousakis warned that warm weather might bring unexpected conditions.
