Sources

Every important claim should lead back to a primary source.

NOAA/CPC current outlooks plus NOAA historical climate analyses.

Primary sources

We prefer NOAA and National Weather Service material over secondary summaries. Each result should be read as an interpretation of these public sources, not as a replacement for them.

Location matching

The checker performs city/state parsing locally in the browser. For 5-digit ZIP codes it uses an embedded ZIP-prefix-to-state table based on the IRS state and ZIP range reference, including listed exceptions. No third-party geocoding request is made by the supplied code.

Update cadence

The embedded ENSO snapshot is from September 10, 2026. NOAA scheduled the next ENSO Diagnostic Discussion for October 8, 2026. The embedded long-lead seasonal outlook was issued August 20, 2026, with the next set scheduled for September 17, 2026.
