Although I missed the aegir (or aegre) last night, a bigger one was promised for this morning. We nearly missed it as it was earlier tan expected by about twelve minutes, and was already approaching by the time we got to the lock. it was a strange, smooth swell of water - caused by the incoming high spring tide meeting the flow of the river. Although it was moving fast, there was something stately and inexorable about it. and then it was round the corner and gone.
