yo i'm having a bit of trouble and i'm worried i've messed up!

Back when the Giza Plains were in the rainy stage, I read that you had to push over trees in order to access secret areas. So, i did this. Now the Giza Plains are dry again! However, i've now see two Level II hunts that require the Giza Plains to be in the rainy period. is there a way to revert it, or do the seasons come again?
