Tier 1: Weighted Mean

Each source gets a dynamic weight based on its 7-day accuracy vs METAR ground truth. Sources that predicted yesterday’s weather correctly get a louder voice today.

MAE-based

Tier 2: Regime Detection

The engine detects the current weather regime — fair weather, frontal, tropical, marine event — and shifts source weights accordingly. Buoys matter more in a gale.

5 regimes

Tier 3: Ensemble Spread

After fusion, the engine measures how much sources disagreed. Tight agreement = high confidence. Wide spread = uncertainty flagged to users. No false precision.

p10–p90

Your island. Your brand. Our engine.

A production-ready weather platform in days, not months. Your branding, your domain, our data pipeline doing the heavy lifting.

Multi-Source Consensus

We blend 20+ sources, bias-correct each against ground truth, and fuse them into a single trustworthy forecast every 5 minutes. Not a single model — a consensus.

White-Label Ready

Your logo, colours, domain, and cultural personality. From the dashboard to push notifications to embeddable widgets for hotels and resorts.

Marine & Reef Intelligence

Wave height, swell, tides, water temperature, and dive conditions. Built for islands where the ocean isn’t scenery — it’s the economy.

Tropical Storm Tracking

NHC integration, distance-from-island alerts, automatic tone escalation.

Custom Weather Vibes

Named weather personalities tied to your island’s culture and context.

Full REST API

Current, hourly, daily, marine, alerts, aviation — all endpoints.
