Birmingham lies at the geographic heart of England. As such, it has a climate that is essentially transitional between northern and southern England in terms of temperature and between Wales and eastern England as regards to rainfall.
Mean annual temperatures over the region vary from around 8 °C to just over 10 °C.
The temperature shows both a seasonal and a diurnal variation. Minimum temperatures usually occur around sunrise and maximum temperatures are normally 2 or 3 hours after midday. Since Birmingham is at some distance from the sea, with its moderating effects on temperature, the annual range is more pronounced than in most parts of the UK. Sharp winter frosts are common and there are occasional very hot summer days.
January is the coldest month, with mean daily minimum temperatures varying from just below 0 °C to about 1.5 °C and July is the warmest month, with mean daily maximum temperatures approaching 22 °C.
