The day was dry and partly cloudy with sunny intervals, moderate to fresh westerly winds, and temperatures ranging between 16°C and 18°C.

A pod of 30 Common Dolphins was seen offshore, moving steadily west.

Butterflies were active in the more sheltered spots, with 52 Red Admirals leading the way. Also logged were 27 Green-veined Whites, 31 Meadow Browns, six Painted Ladies, six Common Blues, and four Large Whites. A single Humming-bird Hawk-moth was seen at the Observatory, darting between fuchsia in the afternoon sun.

Dragonfly sightings included one Emperor Dragonfly and one Migrant Hawker.

Seawatching produced 550 Manx Shearwaters off the west coast, along with 16 Gannets and a single Fulmar. Seven Cormorants and eight Shags were also noted. Gull numbers remained high, with 520 Herring Gulls, 60 Kittiwakes, 16 Black-headed Gulls, six Lesser Black-backed Gulls, three Great Black-backed Gulls, and two juvenile Mediterranean Gulls. 16 Sandwich Terns were seen off Solfach, moving south in loose groups.

Waders were well represented, with  four Whimbrel, eight Curlew, six Turnstones, four Dunlin, two Sanderling, and a single Common Sandpiper all seen on or around Solfach and the Narrows. A lone Snipe, the first of the autumn, was flushed from grass near Pwll G.

 A single Grey Heron was seen in Henllwyn and raptor activity was limited to a single Sparrowhawk.

Passerine movement included 19 Swallows, eight House Martins, 18 Meadow Pipits, 16 Rock Pipits (13 of which were trapped and ringed), and 12 Pied Wagtails. Resident species included 31 Wrens, seven Dunnocks, seven Robins, and a single Blackbird. Two Wheatears and nine Stonechats were also logged.

Warbler activity was led by 57 Willow Warblers, with smaller numbers of three Chiffchaffs, two Sedge Warblers, one Reed Warbler, one Grasshopper Warbler at Nant, being the first of autumn, and one Blackcap. Two Spotted Flycatchers were also seen.

Tom and Bethany were busy on the beach using a portable Heligoland trap to catch Rock Pipits, successfully trapping sixteen birds—thirteen new individuals and three retraps—all fitted with individually marked plastic Darvic rings to allow field identification without the need for recapture.
