It has been far to hot recently so I would like to know how dose your ocs deal with the heat?

Halona probably has the easiest time with hot weather. She grew up in a tropical world and has a much better knowledge of her physical limits being very active and all. Being a lover of the ocean, her go to way to stay cool is swimming.

Nireta is the kind of person who says she handles heat real well, but actually not as well as she thinks. While she grew up in a warmer climate like Halona, she isn't as used to the same level of heat and humidity. Plus, her latest long stays on other planes (Ravnica and Arcavios) have had much more temperate climates comparatively. If she were in this heat, she'd be heavily contemplating going to a plane that's currently in winter.

Catrina's homeplane being more Ireland/Scotland/Britain inspired is stereotypically much cooler. In theory, she'd be the worst at handling the heat, but given the fact that her powers come from taking the strengths and endurance from the things she kills, she just toughs it out.
