Yağmur is the Turkish word for "rain." A poetic modern Turkish feminine name evoking the blessing of rainfall on the Anatolian steppes.
Yağmur Tanrısevsin (born 1989) is the Turkish actress.
Yağmur does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Yağmur reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
