The primary entry point for West View sits at 12.4950 °N, 81.7180 °W (WGS84 datum)[1] — a coordinate that places you roughly 30 m west of the reef wall's crest, in water that averages 28 °C in September and drops to 26 °C during February upwelling events[2]. Type those numbers into a Garmin or a Suunto and you'll get a pin. What the pin won't tell you is that the wall runs NNW–SSE at roughly 340°, the prevailing current runs north, and those two facts together mean entry point selection changes whether this is a relaxed drift dive or a 40-minute fight back to the boat.
That's the gap this article tries to close. The West View spot page stores the canonical coordinates and depth range. What it can't store in a database field is the geometry problem — how an oblique wall interacts with a directional current, what NOAA's SST climatology actually shows for this bounding box across twelve months, and what OBIS occurrence records document within 2 km of that pin versus what dive operators generically advertise. This piece layers those datasets onto the coordinate so the number becomes navigable rather than merely locatable.
A note on methodology: all SST figures come from NOAA OISST v2.1 at 0.25° resolution[2]; current vectors from Copernicus GLORYS12V1 reanalysis[3]; species occurrence counts from OBIS clipped to the bounding box 12.48–12.52 °N, 81.74–81.70 °W; route data from OpenFlights for airport code ADZ. Where those datasets have known resolution limits — and they all do — the caveats are stated explicitly.
