How old is Noah when the floodwaters come upon the earth in Genesis?

Noah is 600 years old when the floodwaters come upon the earth in Genesis.

Genesis 7:6 states that Noah was six hundred years old when the flood of waters came upon the earth. The age is presented after the earlier account of Noah’s family, the ark’s construction, and the instructions to bring living creatures aboard. It is a direct chronological detail in the flood narrative.

The figure should not be confused with Noah’s total lifespan. Genesis 9:29 says that Noah lived 950 years, so the flood occurred 350 years before his death according to the biblical chronology. His sons were already adults and had wives when they entered the ark, but Genesis does not give their ages at that moment.

Later retellings sometimes shift ages because they combine different parts of Genesis or use artistic chronology. The specific age at the start of the flood, however, is 600, while 950 refers to Noah’s lifespan.
