Is it because of Climate change?

Yes, our climate has been affected.

according to me it may be global warming

The weather forecasters are sometimes incorrect. The weather can change rapidly without warning and probably has been doing so before climate change was even a problem.
Although, climate change has been known to cause rapid shifts in weather that aren't considered "normal" so yes, it might have something to do with climate change. Or, it might just be that the weather monitoring technology is malfunctioning in some way.
