Where can you find orcas in the US?

Good day everyone, I'm curious to know, where exactly can one find majestic orcas, also known as killer whales, within the borders of the United States? Are there any specific regions or water bodies where these intelligent marine mammals are commonly spotted? I'd appreciate any detailed insights or recommendations on the best locations and perhaps even the best time of year to witness these incredible creatures in their natural habitat. Thank you in advance for your valuable information.
