No. The magnetic declination can be quite significant even in the continental US, and it isn't determined by latitude alone:

Thanks the correction! I've only used european maps where the deviation is usually small. Local bias...

Thanks for the map; I always thought the declination was pretty tiny. Kind of shocking to realize it's 20° in my house.
