Seasonality (Average by Month)

What am I looking at?

What it shows: the average level of the series for each calendar month (Jan…Dec) across the full history.

Computation: for each month m, take the mean of all observations whose calendar month = m (all years equally weighted).
Interpretation:
- Not seasonally adjusted (NSA): clear recurring peaks/troughs by month.
- Seasonally adjusted (SA): should be fairly flat (seasonality already removed).
Caveats: uses raw levels, so long-run trend can dominate; best for monthly series. For a relative view, consider a seasonal index (month_mean ÷ overall_mean − 1) or limit to the last N years.

What this measures & how to read it

Weighted average based on sampling of approximately 900 retail outlets, 8:00AM Monday. The price represents self-service unless only full-service is available and includes all taxes. See (http://www.eia.doe.gov/oil_gas/petroleum/data_publications/wrgp/mogas_home_page.html) for further definitions. Regular Gasoline has an antiknock index (average of the research octane rating and the motor octane number) greater than or equal to 85 and less than 88. Octane requirements may vary by altitude.

Tip: focus on multi-month trends to reduce noise from seasonality, one-off shocks, and revisions.
