Reading detail
Availability pattern and sample depth
The combined coast number conceals differences between its three component markets and across the forward calendar. The sample disclosure also shows why month to month movement needs care and why no price index is published.

What cleared the release gate
The coast count removes overlap between Llandudno and Conwy; individual area counts are intentionally not additive.

Monthly coast and area series
The coast value deduplicates homes across overlapping area boundaries. The area columns show the same release measured within each local footprint.

Data coverage
From the UK corpus to one coast reading
The North Wales index deliberately narrows the warehouse to three fixed coastal footprints, then removes duplicate homes across their overlap. Corpus scale and the final local sample are kept separate.

Profiles geocoded
119,707 profiles with usable coordinatesWarehouse coverage spans 4 June to 15 August 2026. Profile counts describe the UK discovery corpus, not active supply in this market; every published index applies its own geography, freshness, duplicate and minimum-sample rules. Supporting cuts use the 2 September window. The August release remains visible and is not rewritten.

Methodology and publication notes
Upgraded Intelligence records observed availability for holiday let listings in three fixed North Wales footprints. The coast index combines them, removes duplicate properties and calculates the unavailable share from the observation date through day 30 inclusive, a 31-date window.
Fixed Llandudno footprint
Every release uses the same five kilometre radius centred at 53.3241, -3.8276.
Fixed Conwy footprint
Every release uses the same four kilometre radius centred at 53.2803, -3.8297.
Fixed Anglesey footprint
Every release uses the same ten kilometre radius centred at 53.2646, -4.0899.
Each home counted once
Duplicate listings and overlap between the Llandudno and Conwy samples are collapsed in the combined coast figure.
Samples published
The current release contains 283 unique coast homes; the separate area counts remain visible beside each reading.
Comparison boundary
The sample expanded from 50 homes in August to 283 in September, so the difference between releases is not a pure demand trend.
Availability boundary
Unavailable nights may be booked, owner blocked or otherwise restricted. They are not confirmed occupancy.
Availability only
The current North Wales dataset observes availability but not sufficiently reliable pricing. No nightly rate estimate is published.
