How predictable were the July 2019 European temperature records?

The coming climate 
change catastrophe
is a 100-year prediction
made by people who 
have no idea what the
climate will be like 
in the next year.

Real science does not 
make consistently wrong
wild guesses about the
future climate.

But real science IS working
on predicting local weather
more than a few days 
in advance.

ECMWF is the 
European Centre 
for Medium-Range 
Weather Forecasts.

ECMWF’s 
temperature 
forecasts are for
2-meters up
(from the ground).

Below are forecasts
for three locations 
where national records 
were broken. 

These records are:
(1)
46.0°C 
in the French village of VĂ©rargues 
on June 28; 

(2)
42.6°C 
in the town of Lingen in Germany 
on 25 July; and 

(3)
38.7° C.
in the city of Cambridge in the UK 
on July 25.



The July 2019
heatwave also set 
new temperature 
records in Belgium, 
Luxembourg and 
the Netherlands.


Key findings are that:
(A)
Warmer than average 
temperatures 
were predicted 
between 10 and 
12 days ahead 
of the three events,
although a wide 
range was predicted

(B)
Highly unusual 
temperatures 
were predicted 
between 6 and 
7 days ahead, 

(C) 
A few days in advance,
the predicted temperatures 
were a few degrees lower 
than the observed records.



The forecasts were NOT
for specific weather stations
where the temperature records 
were broken.

The forecasts do cover
the world in a grid pattern.

ECMWF produces 
ensemble forecasts (ENS) 
with a grid spacing of 18 km, 
and a high-resolution
forecast (HRES) with 
a grid spacing of 9 km. 

Predictions were for 
average conditions 
in the grid box,
as a whole.

ECMWF forecasts,
in many parts of Europe, 
tend to under predict 
maximum temperatures 
in the summer.
