Very high to extreme thermal burden is expected today and tomorrow in many parts of Greece, due to the strong and prolonged heatwave in the country.

On Thursday, mercury will reach many areas at 40-42 ° C and locally at 43 ° C while a slight temperature rise is expected on Friday, with mercury reaching or exceeding 44 ° C locally.

At the same time today ‘we enter the most critical period“, As reported by the Flame Pyromeological Group of the National Observatory of the Athens National Observatory.

According to Flame, ‘the cumulative effect of very warm and dry conditions prevailing in our country as early as Sunday, July 20, 2025, has led to a significant increase in the flammability of forest fuels, so that it is very facilitated by launch of firesthe development of large thermal loadsthe rapid spread of the fire and the creation of stains. “

In addition, the potential is reinforced for firefighting fires (self -guided with potentially very high thermal loads) in continental parts of the country today and tomorrow.

Reinforced northwest (NW) winds They are expected today in the Ionian Sea, significantly increasing the pyrboneous risk.

‘From today, until Saturday, July 26, 2025, expected reinforcement of northeast/northeast (B/BA) winds in the eastern mainland and the Aegean, which will lead to significant Enhance the potential for fires guided by the wind (mainly on Friday 25th and Saturday 26th July 2025).

The above leads to a significant and potentially dangerous escalation of pyrological risk, so the difficulty of controlling incidents that may occur will be very high and locally extreme, ”the Flame team points out.

Very high risk of fire today in 10 regions

It is noted that today a very high risk of fire (risk category 4) is foreseen in 10 regions of the country, according to the Fire Risk Risk Charter of the General Secretariat for Civil Protection of the Ministry of Climate Crisis and CivilProtection.gov.gr.
