It is weak compared to the field inside the solenoid, because the same number of magnetic field lines have much more space to occupy. There they spread out, whereas inside the solenoid they are confined in a cylinder.

Magnetic Field Outside A Solenoid

The solenoid is deliberately designed that way. The magnetic field is concentrated on the inside where it is needed to do work, and diminished on the outside where it might be drained off into other objects (losing power).
Inside the solenoid, the various small magnetic fields created by the current flowing in the coils of wire are pointed in the same direction, so they add together their individual forces to produce a stronger field. The area inside of the solenoid is small, so the combined field is concentrated.
Like the guy above me said, outside the solenoid, the field spreads out, and is less concentrated.

The field is directed toward the center of the solenoid and (according to the math) the field actually does not exist the solenoid at all. However since there are no perfect solenoids some of the field leaks. It has nothing to do with field line densities.

I think of a solenoid as I would any electromagnet; with a developed field around it.
