The question was investigated of whether (a) age at which infants start to crawl is related to (b) seasonal temperature six months after birth. “Six months after birth” was targeted as the period in which babies typically first try crawling. For a large sample of babies, (a) the time at which crawling actually began and (b) the average monthly temperature six months after the birth month was collected.

Month	Average Age Starting to Crawl (weeks)	Average Temperature 6 Months After Birth Month (in units Fahrenheit)
January	29.84	66
February	30.52	73
March	29.7	72
April	31.84	63
May	28.58	52
June	31.44	39
