Hot Weather /Lower Bloods

I've been type 2 for 16 years but had to go on insulin this year . It took a while to get the morning/evening insulin in reasonable balance , but results have been bouncing around . This week for the first time in months we have had warmer weather and despite eating much the same food ,my bloods have been much lower , so I'm having readings of 3 to 4, very low for me .
Does anyone else find warm weather affects their readings ?
