Mandarin Beach Villa beachfront observations — 5 October 2026, Lipa Noi
Coverage: the beachfront and water visible from Mandarin Beach Villa’s fixed camera only. Conditions at other properties are not observed. Reporting period: 5 October 2026, Thailand time.
Automated observations of the beachfront directly in front of Mandarin Beach Villa, from the villa’s own fixed camera at Lipa Noi, Koh Samui. Each entry summarises footage sampled during that hour, in Thailand time. Hours with no entry were not sampled; hours whose footage could not be assessed say so.
Owner-operated automated visual observations. These are not water-quality tests, official tide measurements or confirmation that swimming is safe.
Time-lapse of the day's sampled frames, 5 October 2026 — the same privacy-cropped frames as the archive, played in order.

12 frames sampled across 60 seconds of footage. Sampled footage from the preceding hour, not continuous coverage.
Limitations
["Frames cover a short observation window so longer-term changes in waterline or wave activity cannot be assessed", "Areas beyond the camera's fixed field of view, including the wider beach and open sea, cannot be assessed", "No scale reference is present, so exact distances or dimensions cannot be determined"]}
These observations describe only the beachfront and water visible from Mandarin Beach Villa's fixed camera during the sampled window; they do not establish conditions elsewhere along Lipa Noi or outside another property.

Limitations
Footage covers only a short sampled window so longer-term changes in water or sand conditions cannot be determined

Water surface appears smooth to faintly rippled across all frames A faint line of small breaking wavelets is visible near the waterline in several frames No whitecaps visible anywhere offshore
Observed waterline
Waterline sits at a fairly consistent distance from the foreground loungers and umbrellas across all frames A continuous band of exposed sand separates the loungers from the water's edge in every frame No visible change in how far the water reaches toward the vegetation or loungers across the sampled frames
Visible sand and debris
Numerous footprints visible in the sand but no litter or natural debris discernible in the assessed area
Beach condition
Wide band of dry, exposed sand visible between the loungers and the waterline in all frames Footprints present across the sand but no standing water or wave wash reaching the lounger area No visible accumulation of debris on the assessed sand
Visibility
Adequate — Frames are well lit (sunset scene) with clear foreground sand, loungers, and waterline visible; only the sun's glare on the water slightly limits detail directly along the horizon.

Observation detail
Observation ID MBV-OBS-20261005-175023-B90D
12 frames sampled across 60 seconds of footage. Sampled footage from the preceding hour, not continuous coverage.
Limitations
These observations describe only the beachfront and water visible from Mandarin Beach Villa's fixed camera during the sampled window; they do not establish conditions elsewhere along Lipa Noi or outside another property.
