I can assure you that that autumn was particularly hot, Cordoba gave me a bit of a hard time in the hottest hours but it was less windy. In Cadiz, the wind always blows but the heat wave, a bit abnormal for the period, had subsided a lot. In general, I would tell you that if you plan to visit the cities in the interior, it is best to go in the autumn or even, as they suggested to me during my trip, at the end of February.
