Only 7 completed matches are recorded in the last 365 days—insufficient history to identify a reliable typical start time or month.
These figures use completed PhotoWeather MatchEvent records from the previous 365 days only. They describe recorded forecast matches, not observations, climatological probability, or a guarantee of future conditions.

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.
