BME280 temperature fluctuations

Hardware
1

I have been using a BME280 sensor in combination with ESP32 (barebone) to monitor the enviornment on our balcony for over 6months. Recently (as in the past 4-5 days) I have noticed some crazy fluctuations occurring for a moment, then back to the expected value.
As anyone seen similar using this (or other) sensors?

I’m doing very little with the code/configuration for this device. There is a DeepSleep which runs 15sec on, 1/2hr off.
