Can weather affect BBT?

[CarolineB]

Hi,
I am just wondering if the weather can affect BBT?
Mine have been flat for about 5 days now, always exactly 37.1, this morning it was 37.3 and the weather has just got a whole lot hotter? Nothing else had changed ie same time etc.
Just curious if this can affect bbt? Anyone know?

Mine increased by about 0.2c this morning too after being flat for 4 days !!! perhaps it is the weather ??? x

Hi, I am sure it can, I notice a drop everytime I wake up without the duvet on. I am tempted to roast in bed rather than change to a summer cover and mess up my nice neat chart!! Oh dear how sad am i??
