On the Mediterranean coast we have some moderating effects from the sea, so we have been having maximum temperatures of 32 to 34 degrees, although 36/37 is forecast for the start of next week. Inland, it has been much more oppressive (and still is). Madrid has regularly seen 40 degrees and both Sevilla and Córdoba have been as high as 42 degrees. This is nothing new. It happens every year; but not as early as this! Usually we associate this degree of heat with late July and August, so the question on people's minds is, is this a spike or must we endure it - and possibly higher temperatures still - until early September? And if it is indeed an early start to the hot weather, why should we assume that it will subside on time?
Fortunately, when we renovated our property after buying it we drew on our experience of visiting family in Northern Queensland during their summer. As a result, we installed air conditioning units in the living room and all three bedrooms, as well as ceiling fans, so we are able to combat the heat in a way which most of our Spanish neighbours can't. Our winter heating allowance actually gets spent as a summer cooling allowance.
