Beach
noun
The kanji and the word are exactly the same. That means they share meanings as well. It's worth mentioning that a more common way to say beach is ビーチ, and many people actually say 海 even though this literally means "sea".
はま
The reading is the same as the one you learned with the kanji.
エンジンの調子がおかしくなったので、浜に着くほんの手前で車を止めなきゃいけなくなっちゃったんだよ。
Our car’s engine was making strange sounds so we had to stop right before we were going to arrive at the beach.
