The first week we had a lot of sunshine, but then we were surprised by rain showers and cool weather. But for the most part, it was quite pleasant to be outside.
SachaIt was cool and there were a few rainy days. But there were also bright, sunny days. It could have been better, but not terrible.
Jochem OttinkThe temperature was pleasant for autumn walks. A little sunshine would make it even nicer.
