Odd phenomenon while riding me bike - what is it?

Hey! I am not sure if this is the right subreddit for this question. Whenever I ride my bike through one particular spot I notice an immediate change in temperature. You can feel it on foot too but on bike its more abrupt cause of the speed. It is in central Europe in a total plain. No bodies of water or mountains in many many many kilometres. On one side of the road there are train tracks and on the other there is some vegetation, few bushes and grasses. The temperature suddenly drops and its very noticeable, especially when on a bike. I asked my friends if they feel it too and they confirmed. Its been there since I was a kid and I always wonder how is it possible? I know it gets a bit cooler when I enter a forest but the change is gradual and not as big. In this magical spots case it is super sudden and noticeable and its always there. What is this phenomenon called and what can cause it?

EDIT: Time of day did not matter, it happened both during the day and at night.

EDIT 2: One more thing I have noticed is that there is different vegetation in immediate surroundings of this area. There are only grasses lots of bushes and leafy trees like oaks and everywhere else in this region there are mostly pine trees like 99% are pine trees. And this odd area is no pine trees at all, only leafy trees.
