| As to why weather can have an impact, I don't have a really good answer. But it does seems the case that people's metabolism can sometimes change in different temperatures.
For me, hot weather often increases my basal needs - at a guess, a hot summer day I can need maybe 20% more, and I need to be very careful with meals and bolusing too - as my BG loves to go high in the heat - and stubbornly stay there.
