Since pressure in the veins is normally relatively low, for blood to flow back into the heart, the pressure in the atria during atrial diastole must be even lower.So this means that veins have blood pressure.

Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. ... As vessel diameter decreases, the resistance increases and blood flow decreases. Very little pressure remains by the time blood leaves the capillaries and enters the venules.
