Noticed the repeated reports of very high (for the time of year)
temperatures in Brussels the last couple of days, yet in Southern
England I don't think we've reached 20C. According to the weather
charts no front lies between here and Brussels ATM so I'm rather
surprised. In a typical summer heatwave there's little difference
between Brussels and Southern England, and the quoted Brussels average
max temps (in another thread) of 13C in April and 20C in June are
pretty much exactly the same as inland Southern England... suggesting
it basically has the same type of climate, broadly speaking.
