Also, doublecheck the readings from this sensor. There has been plenty of report about the temperature reading being much higher than the actual temperature (in my case, I got 4C higher than ambient). Some people says it has self-heating problem since if you put active airflow the temperature dropped.

Yes, the BME280 is very good at sensing temperature deltas, much less at sensing absolute temperature. A correction factor is most often needed with this device.

I live in Michigan so I would leave it be- a few extra degrees of warmth would maybe act as a placebo effect
