I'm not convinced the term 'sea breeze' is correct for inland waters. 

Jim C is quite right about heating and gradients.  Plymouth is a great example - on a hot day the south facing slopes of Dartmoor heat, air rises and cooler air is sucked in off the sea giving the sea breeze.

Inland waters probably get a similar effect from local features.  I have heard that Datchet can get some type of 'sea breeze' (probably should call it thermally induced breeze) from the heating of the tarmac at Heathrow. 

Can't think what local feature at Grafham or Hunts would induce this effect, but i really can't believe that its the sea breeze from the Wash.  The flow cell for that air movement would cover most of East Anglia.

At risk of raising an old topic.  Sea breezes do occur over Northern East Anglia under specific conditions.  They do tend to flow from the wash direction, and tend to be more prevelant here and make it further inland than elsewhere in the country as suface friction is low (have you noticed how flat it is?) and the massive thermal effect of the huge fields and dark earth in mid spring (before the crop cover becomes to thick)

However the breeze is rarely very strong and doesn't last very long, usually 1500-1700ish.

I might be sailing it, but it's still sh**e!
