Provider hardware history is preferred before Senlay snapshots and model history. - 7-day rhythm: 8 usable daily cycle(s). Average low 0 km/h near 00:04; average daytime peak 8.9 km/h near 12:26, usually from 233° (SW). - Recurring daytime ramp: ramp detected on 3/8 day(s), usually starting around 13:08. - Kitesurfing week threshold: daytime peak reached the ~22 km/h (12 kt) practical minimum on 0/8 day(s); otherwise the pattern is light or marginal. - Today does not show a strong clean sea-breeze ramp yet: low 0 km/h at Today 00:04, peak 4 km/h at Today 00:49. - Strongest wind in the 7-day lookback was 2026-07-02 18:09: 20.6 km/h, gusts 0 km/h, from 233° (SW); do not extrapolate that stronger window into now. - Kitesurfing decision memory: current hardware/model truth is only 0 km/h (0 kt), below normal riding range. - Kitesurfing threshold check: today's local peak 4 km/h (2.2 kt) is still below the ~22 km/h (12 kt) practical minimum for most riders. - Hardware/model agreement: MODERATE (50/100). Primary anchor: Hoi An Flow 3.4km away. Wind speed hardware 0km/h vs model 9km/h; direction difference 9deg. Model rhythm is usable as context, still secondary to nearest valid hardware. - Agent rule: include the weekly local wind rhythm in the answer; never decide from the current average wind alone. --- DOMAIN LOCAL PATTERN MEMORY (API STRUCTURED SUMMARY) --- Priority rule: If a primary hardware sensor is present, Senlay first tries that provider history log. If unavailable, it uses Senlay stored hardware snapshots for the coordinate. If that is insufficient, it falls back to 7-day model history.

These adjust raw data for local terrain, coastal, and atmospheric effects. Standard weather APIs do NOT include these corrections. MODIFIER HAZARDS: sensor_site_temperature_bias, sensor_site_pressure_bias, coastal_cliff_effect, pressure_sensor_model_divergence • Surface wind 0 km/h estimates 0 km/h at 50m and 0 km/h at 100m • Temperature site calibration: f062e7cd Hoi An Flow, 3.4 km from point reports 28.7°C from complex terrain / elevated land at 0m; target is complex terrain / elevated land at 5m. Lapse/terrain-adjusted target estimate 28.1-29.2°C using 6.5°C/km and the dense 49-point, 20km sensor terrain profile. • Pressure site calibration: f062e7cd Hoi An Flow, 3.4 km from point reports 1016.6 hPa at a 0m sensor site; target elevation is 5m. Target local-pressure estimate 1015.6-1016.4 hPa after barometric elevation transfer. Reported MSL/altimeter pressure is kept intact; this range is for local physical pressure at the spot. • Night-time coastal location: light offshore land breeze possible (land cools faster than ocean). Wind may shift offshore direction. • Coastal cliff/headland detected (184m). Wind may accelerate around headlands and create turbulent wind shadow behind cliffs. • Ventilation Index: 0 m²/s (POOR — pollution accumulates). Mixing height ~100m, wind 0 km/h. Poor air dispersion — avoid outdoor exercise. • Maritime thermal buffering: 43% of surrounding area is ocean. Diurnal temperature range suppressed by ~3°C vs inland. Current 28.7°C is moderated — inland locations at same elevation may be 3°C warmer (daytime) or colder (night). • Pressure trend (model series): -1.5 hPa over 3 hours (model 1006.4 hPa now, was 1007.9 hPa; headline sensor-grounded pressure is 1016.6 hPa). Slow drop — watch for weather change. • Parallel wind speed: sensor-grounded 0 km/h vs model-layered 9 km/h (delta -9 km/h, minor divergence). Sensor path uses target terrain modifier only. • Parallel temperature: sensor-grounded 28.65°C vs model-layered 27.8°C (delta +0.85°C, small divergence). Sensor path includes lapse-rate and terrain-exposure transfer. • Parallel reported pressure: sensor-grounded 1016.6 hPa vs model-layered 1006.8 hPa (delta +9.8 hPa, major divergence). Sensor local-pressure target range 1015.6-1016.4 hPa. Terrain-calibrated temperature estimate: 28.1-29.2°C (raw sensor 28.7°C) Terrain-calibrated local pressure estimate: 1015.6-1016.4 hPa (reported 1016.6 hPa) Parallel sensor-vs-model divergence: 3 compared field(s), 1 major divergence(s). Sensor-grounded path remains the physical anchor. --- CALCULATED INSIGHTS (Senlay data fusion) --- • Wind force: Beaufort 0 (Calm) • Wind trend (past 3h to now): RISING (was avg 2 to now 8 km/h, Δ+6) • Wind forecast (next 3h): STEADY (+2 km/h) • Wave energy index: 0.4 (Small — longboard/beginner) • Forecast trust check: MODERATE (50/100). Primary anchor is Hoi An Flow (3.4km); farther hardware is comparison only. • Wind speed: nearest hardware 0km/h vs model 9km/h — MINOR (Δ-9km/h). • Wind direction: nearest hardware 233deg vs model 224deg — AGREE (Δ9deg). • Temperature: nearest hardware 28.7C vs model 27.8C — AGREE (Δ0.9C). • Forecast trend: model wind is falling over 3h (17.5 -> 10.4 km/h); trend trust follows live divergence: moderate. • Parallel tracks: sensor-grounded + modifiers vs model + modifiers compared 3 field(s); strongest divergence is pressure Δ9.8 hPa. HAZARD FLAGS (1): - Major sensor/model divergence for pressure: sensor-grounded 1016.6 hPa vs model-layered 1006.8 hPa --- LIVE WIND SENSORS (physical hardware — HIGHEST PRIORITY DATA) --- 2 private sensor(s) detected near your location. These are REAL physical instruments, not weather model estimates. Selection rule: nearest valid hardware sensor is the primary anchor; farther hardware is used for comparison and uncertainty, not as the main truth source. Primary readings get minimum local terrain modifiers. Farther readings can use extended source-to-target modifiers for comparison. [WINDY] Hoi An Flow (3.4km away) — PRIMARY NEAREST HARDWARE Wind: 0 km/h from 233° Sensor terrain profile (20km range): elevation 0m, local range 136m, land point Temperature: 28.7°C Updated: 2026-07-06T18:14:09.000Z Type: Windy Stations API v2 observation; demo read-only integration. [METAR] Da Nang, Vietnam (23.5km away) — comparison hardware Wind: 1.9 km/h Sensor terrain profile (20km range): elevation 8m, local range 663m, land point Temperature: 28°C Type: Official aviation weather observation (METAR) — highest reliability CROSS-REFERENCE: 2 sensors average 1 km/h (range 0-1.9). Confidence: moderate. --- MOVING SHIP OBSERVATIONS (mobile marine hardware — comparison layer) --- Source: NOAA/NDBC Ship Observations / VOS-style marine reports. These are moving platforms, so they compare offshore conditions but do not override nearest fixed hardware at the target. Public NDBC reports often anonymize vessel identity as SHIP; Senlay keeps a per-report label from source, position, and time.

Not a physical sensor and not navigation-grade. Current model tide/sea-level height: 0.67m (model_sea_level_height_msl) Phase: rising Next high: 2026-07-07T03:00 (0.8m) Next low: 2026-07-07T09:00 (0.6m) Model tide range in table: 1.22m No live tide gauge was available. This fallback is derived from the marine sea-level model, not a physical sensor or navigation-grade tide table. --- SEISMIC ACTIVITY --- No seismic activity detected within 500km. --- ACTIVE FIRES --- No active fires detected within 100km. === END PHYSICAL WORLD MODEL === === Senlay - Physical-World Context API for AI Agents ===
