I live in the Midwestern US, for context.
I understand that La Niña and El Niño are more or less cyclical (ignoring ENSO Neutral which just seems to more often than not just be a transition between the two) and that weather effects differ depending on where you are in the world. But it seems as if every time there’s a transition between the two, no matter if we’re transitioning to La Niña or El Niño, it somehow means that we’re “really in for a hot one this year!”
[A 2024 article from CNN explaining that La Niña makes it hot](https://www.cnn.com/2024/06/13/weather/el-nino-la-nina-summer-forecast-climate/index.html).
[A 2020 article, also from CNN, indicating that El Niño leads to higher world average temperatures](https://amp.cnn.com/cnn/2020/09/10/weather/la-nia-is-here-trnd)
Surely they can’t both mean hotter than normal, right? We’re almost always in one or the other. If it’s hotter than average all the time, then that’s the new average.
Make it make sense.

El Niño means the Pacific Ocean is hotter than usual
La Niña means the Pacific Ocean is cooler than usual
The Pacifc Ocean doesn’t greatly affect you, being in the Midwest, nor me, being in the Northeast. We have the Great Lakes affecting our weather, and I also have the Atlantic.
El Niño means hot temperatures for the West Coast (because hot water means hot air)
La Niña means less rainfall for the Pacific Northwest (because less water is evaporated from the ocean) which naturally makes it warmer, since there’s no rain to cool things down. This generally leads to cooler temperatures on the West Coast, but it doesn’t have to.
