I have been out in 2.3m tides and 0.7m tides. In all honesty I prefer the 0.6 to 1m tide ranges. A little bit of a walk but your legs are nice and warmed up by the time you get there.
I have been out there in 2+ metre tides with higher winds - 20-28knots and it is no where near as much fun because it gets choppy and more like a roller coaster ride. Unlike wave beaches where you can enjoy the gentle curves between wave sets it is more like a constant barrage of knee to waist high chop and can be quite exhausting.
The absolute best days I have had out at Parham have been at the lower ends of the tide, smooth as silk, cruise forever and nice forgiving waist high water for miles.. perfect for beginners to pros :)
EDIT: Great photos GodFather - hard to really believe how fast the tide comes in until you see it
