According to Genesis, how old was Noah when the floodwaters came?

According to Genesis, Noah was 600 years old when the floodwaters came. Genesis 7:6 states that Noah was six hundred years old when the flood of waters came upon the earth.

The age appears within a genealogy and chronology that gives unusually long lifespans to several antediluvian figures. Genesis 5:32 says Noah became the father of Shem, Ham, and Japheth when he was 500 years old, while Genesis 9:28 records that he lived 350 years after the flood.

The 600-year figure is specifically tied to the flood’s arrival, not to the completion of the Ark or the beginning of the divine warning. The narrative does not give a separate exact date for every construction stage.

Noah’s total lifespan in Genesis is 950 years. That later figure should not be substituted for his age at the flood, which the text states as 600.
