Boyfriend and dad issues

So I'm technically not supposed to date until I turn 16 but that's all the way in August. I'm afraid about what my dad will say/do when he meets my bf for the first time. I'm fully white and my dad said he wants white blood in the family. He is kind of racist btw. My boyfriend is hispanic/white mixed. My dad is especially racist towards hispanic/black people. (I'm sorry yall) My bf has a huge heart and is extremely kind and I don't know how I should break it to my dad. Any advice?
