West coast macro funds

edit: Sorry, just reread your post and saw you asked about presence vs. HQ and that's a bit different. The main reason why macro funds have offices in different locations are 1) business reasons to better trade different markets / access localized knowledge in different time zones (and there are no markets with West Coast time zones) or 2) satisfy personnel (this is why many funds have offices in low tax locations like Florida, and to a lesser extent Texas). Description below describes mostly why talent does not tend to like West Coast.

In general no - its very difficult from a markets hours perspective.

Asia Hours: People in combination of Singapore / Hong Kong / Tokyo. Primarily focus on Asian markets. Tend to be focused on those markets with not a ton of global macro.

Europe Hours: People in combination of London / Paris / Milan / Zurich. 9am - 6pm, work later in evening after dinner if big events in East Coast Afternoon. This is the sweet spot as it straddles all 3 major market time zones (Asia, Europe, North America) and for that reason the biggest concentration (this is a bit debatable with New York) of global macro professionals.

East Coast Hours: People in New York. 7am - 5pm, some late evening from time to time based on big events in Asia, some early morning required to catch some big events in Europe. Very reasonable hours with slightly earlier day than London.

West Coast Hours: 5am - 2pm, some evenings to manage big events in Asia, pretty much impossible to catch big events in Europe.

For the hours reason, West Coast is just not a popular region for macro focused folks as it requires such an odd work schedule that really infringes on general life. Don't get me wrong I know some people who do it - go to work at 5am, done at 2pm, play golf from 3pm-6pm, dinner with wife + kids, asleep by 9-10pm, but it leaves little flexibility and requires pretty tight sleep management.

To answer your answer question on which funds, the biggest macro player is PIMCO in Newport (though I've heard they work insane hours of like 6am-8pm). Peter Thiel used to run a large macro fund called Clarium in SF around 15 years ago but it suffered from poor returns and was converted into a private structure called Thiel Macro now in LA. I am not really aware of that many other folks doing macro out there (though I'm sure there are some platform pod offices and smaller / medium shops that I'm not aware of).
