Must One Wear a Kippa at the Mikveh, Beach or Pool?

The Zechor Le'Abraham (Rav Abraham Alkalai, 1750-1811) observes that some people ensure to keep their heads covered while walking about in the Mikveh, and not only when they actually immerse. He writes that this is an unfounded stringency that has no basis or reason. He explains that the Shechina does not reside in the bathhouse, and so there is no need to cover one's head, an act which is intended to make us aware of G-d's presence above us. The Hida (Rav Haim Yosef David Azulai, 1724-1806) similarly writes that there is no reason to cover one's head while in a Mikveh. The Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909) clarifies that this refers to the interior part of the Mikveh. In the outer room, where people get changed, it is proper to keep one's Kippa on his head. One should keep his Kippa on until he leaves to the interior room to shower and immerse, and should put it back on his head immediately upon returning to the outer room to get dressed. The Kaf Ha'haim (Rav Yaakob Haim Sofer, Baghdad-Jerusalem, 1870-1939) recommends placing one's hand over his head while walking about in the Mikveh, though the consensus does not follow this view. The Yalkut Yosef writes that the beach has the status of a bathhouse in this regard, and thus one may keep his head uncovered at the beach not only when he is in the water, but also when walking about or relaxing near the water. Of course, he should put his Kippa back on upon returning to the lounge. And it goes without saying that if a person wishes to eat while at the beach, he must wear a Kippa for the recitation of the Berachot and while he eats. (Incidentally, if a person wishes to eat bread at the beach, he may dip his hands in the ocean water in lieu of Netilat Yadayim, and recite the Beracha "Al Tebilat Yadayim.") This applies to a pool, as well. One may keep his head uncovered even while sitting at the poolside, except when eating. The Yalkut Yosef cites Rav Chaim Kanievksy as ruling stringently in this regard, and requiring one to wear a Kippa at the beach or pool when he is not in the water, but Halacha follows the lenient position. Summary: One is not required to wear a Kippa at the Mikveh, at the beach, or at the pool, even when he is not in the water. In the Mikveh, one should cover his head only in the outer room, where he changes. One who wishes to eat at the beach or at the poolside must wear a Kippa for reciting the Berachot and eating.
