Mawddach Estuary Sunset Timelapse #1

The story behind this video

A sunny Friday afternoon in late April 2018 found my wife Liz and I making one of our longer excursions to a welsh beauty spot, Cregennan Lakes above the Mawddach Estuary in Snowdonia on the welsh coast.

As we were driving along the Mawddach valley, before turning off for the climb up to the lakes, we noticed what we thought was a forest fire filling the sky ahead with fumes.

But as we climbed up to the lakes themselves we realised that what we thought was smoke was, in fact, a huge, dense, billowing sheet of sea mist coming in off the Irish Sea and filling the Mawddach Estuary with an impenetrable blanket of fog.

Up high at Cregennan Lakes, at the foot of Cader Idris, the sun was shining and we had a lovely hike along the lakeside paths before returning to the car park.

We had planned to drop down to the coast at Fairbourne after our exercise, but after checking that the fog was still covering the coast and valley we decided to stay put in the sunshine instead!

As the day wore on and sunset approached the fog was still there, swirling and billowing around the hills and valley of the Mawddach estuary.

I wasn't going to let such a marvellous opportunity pass by, so we delayed the start of our long drive back home for a couple of hours, watching and photographing in a semi-delirious state as the sun sank lower and lower, eventually disappearing below the surface of the fog blanket.

But the beauty didn't end with the setting of the sun, as the fog continued to swirl as the sky near the horizon took on a gorgeous orange hue, forming a great colour contrast with the blue tones of twilight reflecting off the mist from the heavens above.

Needless to say, it was very late when we got back home, but well worth staying out to witness such a dramatic weather phenomenon.
