Average low 10.3 km/h near 03:00; average daytime peak 22.2 km/h near 11:30, usually from 249° (WSW). - Recurring daytime ramp: ramp detected on 7/8 day(s), usually starting around 08:00. - Weekly gust memory: 8/8 day(s) had gust factor >=1.7x during usable wind, so gust checks stay important even when average wind looks acceptable. - Kitesurfing week threshold: daytime peak reached the ~22 km/h (12 kt) practical minimum on 4/8 day(s); otherwise the pattern is light or marginal. - Today does not show a strong clean sea-breeze ramp yet: low 1.4 km/h at Today 08:46, peak 18.5 km/h at Today 08:00. - Strongest wind in the 7-day lookback was 2026-08-18 12:00: 32.2 km/h, gusts 58 km/h, from 252° (WSW); do not extrapolate that stronger window into now. - Gust pattern: 7-day peak gust factor reached 3.9x at 2026-08-16 16:00. Treat the location as gust-sensitive when average wind is near a decision threshold. - Kitesurfing decision memory: current hardware/model truth is only 1.4 km/h (0.8 kt), below normal riding range. - Kitesurfing threshold check: today's local peak 18.5 km/h (10 kt) is still below the ~22 km/h (12 kt) practical minimum for most riders. - Hardware/model agreement: LOW (0/100). Primary anchor: Hoi An Flow 3.4km away. Wind speed hardware 1.4km/h vs model 14.8km/h; direction difference 6deg. Treat nearest hardware as current truth; use weekly/model rhythm for timing and uncertainty, not as a launch/operation authority. - 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. Wind selected source: senlay_hardware_snapshot_history (senlay_local_store); points 27, span 166h. Marine selected source: marine_model_history (open_meteo_marine); points 192, span 169h.

Use terrain elevation for wind exposure and shelter.

These adjust raw data for local terrain, coastal, and atmospheric effects. Standard weather APIs do NOT include these corrections. MODIFIER HAZARDS: sensor_site_gust_bias, calibrated_gust_risk, sensor_site_temperature_bias, sensor_site_pressure_bias, wind_speed_sensor_model_divergence, wind_gust_sensor_model_divergence, pressure_sensor_model_divergence • Surface wind 1.4 km/h estimates 2 km/h at 50m and 2 km/h at 100m • Sensor-site gust calibration: f062e7cd Hoi An Flow, 3.4 km from point has complex terrain / elevated land exposure while the target is complex terrain / elevated land. Raw gust factor 3.93x (1.4 -> 5.5 km/h); terrain-transferred estimate at the target is 5.5-6.3 km/h, gust factor 4.18-4.39x. Confidence medium. Generic DEM transfer from complex terrain / elevated land to complex terrain / elevated land. Mean wind follows roughness exposure; gust delta follows roughness and relief contrast. • Temperature site calibration: f062e7cd Hoi An Flow, 3.4 km from point reports 32.7°C from complex terrain / elevated land at 0m; target is complex terrain / elevated land at 5m. Lapse/terrain-adjusted target estimate 32.1-33.2°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 1014.9 hPa at a 0m sensor site; target elevation is 5m. Target local-pressure estimate 1013.9-1014.7 hPa after barometric elevation transfer. Reported MSL/altimeter pressure is kept intact; this range is for local physical pressure at the spot. • Ventilation Index: 39 m²/s (POOR — pollution accumulates). Mixing height ~100m, wind 1.4 km/h. Poor dispersion can concentrate pollution; check an actual AQ measurement before changing activity. • ET₀ (Reference Evapotranspiration): 4.2 mm/day — Moderate — typical warm day. Monitor soil moisture.. VPD 2.08 kPa, wind 0.3 m/s. • Pressure trend (model series): +1.7 hPa over 3 hours (model 1004.5 hPa now, was 1002.8 hPa; headline sensor-grounded pressure is 1014.9 hPa). Slow rise — conditions likely stabilizing. • Parallel wind speed: sensor-grounded 1.35 km/h vs model-layered 14.8 km/h (delta -13.45 km/h, major divergence). Sensor path includes source-terrain gust/wind transfer. • Parallel wind gust: sensor-grounded 5.9 km/h vs model-layered 32 km/h (delta -26.1 km/h, major divergence). Use this to detect when the model misses sensor-observed gust structure. • Parallel temperature: sensor-grounded 32.65°C vs model-layered 30.2°C (delta +2.45°C, minor divergence). Sensor path includes lapse-rate and terrain-exposure transfer. • Parallel reported pressure: sensor-grounded 1014.9 hPa vs model-layered 1004.5 hPa (delta +10.4 hPa, major divergence). Sensor local-pressure target range 1013.9-1014.7 hPa. Terrain-calibrated gust estimate: 5.5-6.3 km/h, gust factor 4.18-4.39x (raw 3.93x) Terrain-calibrated temperature estimate: 32.1-33.2°C (raw sensor 32.7°C) Terrain-calibrated local pressure estimate: 1013.9-1014.7 hPa (reported 1014.9 hPa) Parallel sensor-vs-model divergence: 4 compared field(s), 3 major divergence(s). Sensor-grounded path remains the physical anchor. --- CALCULATED INSIGHTS (Senlay data fusion) --- • Wind force: Beaufort 1 (Light air) • Raw gust factor: 3.93x. Terrain-calibrated target estimate: 4.18-4.39x, gusts 5.5-6.3 km/h (DANGEROUS after terrain calibration). • Wind trend (past 3h to now): FALLING (was avg 18 to now 15 km/h, Δ-3) • Wind forecast (next 3h): RISING (+7 km/h) • Wave energy index: 0.95 (Small — longboard/beginner) • DATA GAP: BATHYMETRY — no datum-qualified seafloor data. Reef, shoaling, and depth-limited breaking inference is disabled. • Forecast trust check: LOW (0/100). Primary anchor is Hoi An Flow (3.4km); farther hardware is comparison only. • Wind speed: nearest hardware 1.4km/h vs model 14.8km/h — MAJOR (Δ-13.4km/h). • Wind gust: nearest hardware 5.5km/h vs model 32km/h — MAJOR (Δ-26.5km/h). • Wind direction: nearest hardware 233deg vs model 239deg — AGREE (Δ6deg). • Forecast trend: model wind is rising over 3h (16.1 -> 21.5 km/h); trend trust follows live divergence: low. • Parallel tracks: sensor-grounded + modifiers vs model + modifiers compared 4 field(s); strongest divergence is wind_gust Δ-26.1 km/h. HAZARD FLAGS (4): - Terrain-calibrated gust factor still reaches 4.39x — experts only, verify locally - Major sensor/model divergence for wind_speed: sensor-grounded 1.35 km/h vs model-layered 14.8 km/h - Major sensor/model divergence for wind_gust: sensor-grounded 5.9 km/h vs model-layered 32 km/h - Major sensor/model divergence for pressure: sensor-grounded 1014.9 hPa vs model-layered 1004.5 hPa --- OBSERVED WIND SENSORS (physical hardware; use only with stated time, freshness, QC, and site relevance) --- 2 nearby sensor(s) detected. These may be public, partner, or privately operated instruments. 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.

Not a physical sensor and not navigation-grade. Current model tide/sea-level height: 0.42m (model_sea_level_height_msl) Phase: falling Next high: 2026-08-22T03:00 (0.91m) Next low: 2026-08-21T11:00 (0.34m) Model tide range in table: 1.05m No live tide gauge was available.
