I can recall in 2018, there was a similar day here in England. The sky and the light changed, our perception of colours totally skewed. It was due to a double up of Sahara dust in the atmosphere and the forest fires in Portugal and Northern Spain. Particles rising up into the atmosphere and spreading far and wide. It lasted for only seven hours or so before clearing the next day.
So it must be even worse for you being much closer to the source.
