Good afternoon, everyone.

The Greek April record was reset this afternoon after a very brief
+37.6C reading at the airport of Irakleio due to the Föhn effect of
the southerlies -a very big contrast compared to other areas in
Greece, the south parts of the island or, indeed, the same spot a few
minutes after and before the maximum temperature reading.

The airport of Chania, which saw its record break, too, reported the
following two METARs just an hour ago:
3:00 PM 36°C / 1°C / 5% / 1007 hPa / West 29.6 km/h
3:20 PM 25°C / 13°C /47% / 1008 hPa / NW / 35.2 km/h

People from northern Crete are reporting extremely different
temperature experiences from minute to minute, depending on whether
the wind comes directly from the (up to) 2456m peaks or from the
coast.

The Föhn effect is very typical in April, especially in northern Crete
and parts of eastern continental Greece, making some -both spatially
and temporally- non representative station records stand out. The
beginning of the southerlies was visible as advection fog in Athens,
too, on Saturday, as air originating from Sahara found its way to
Greece after having passed over the still relatively cool
Mediterranean.

Enjoy your afternoon, everyone.
Yannis.
