71-hour requirements breakdown

When available, this detailed table covers only the stated 71-hour horizon (typically 72–168 hours, depending on available hourly data). Opportunity records above span the full 14-day forecast period, so this table does not explain that entire period. Times shown in Pacific/Honolulu.

Requirements breakdown is temporarily unavailable or expired. This does not mean no opportunities.

How this forecast is made

Opportunities are threshold-based signals: PhotoWeather checks whether forecast conditions match the rules for a photography scenario. They are planning guidance, not guarantees. Forecasts can change as new model runs arrive, and confidence generally decreases farther into the forecast horizon, so recheck conditions before travelling.

The weather forecast foundation comes through Open-Meteo , which aggregates models from weather agencies. PhotoWeather applies condition-specific thresholds and derived calculations; not every condition uses every model or data input.
