How We Rank And Verify January Warmth?

We base our rankings on NOAA National Centers for Environmental Information (NCEI) 1991–2020 Climate Normals. These are authoritative 30-year averages computed from over 15,000 stations. We compare daily high/low temperatures, precipitation, and wind speed.

Ranking criteria extend beyond average highs. Real-world comfort matters. We analyze dew point humidity to assess all-day outdoor feasibility for hiking or city walking. We also weigh rain probability, penalizing wet-season locales.

UV index forecasts from NOAA/EPA reports inform sun exposure risks. Water temperature thresholds define swimming comfort. For example, Hawaii’s 77°F (25°C) Pacific feels pleasant, while Southern California’s 58°F (14°C) water demands wetsuits.

Transparent sourcing builds trust. We rely on NOAA/NCEI Climate Normals for temperature data. Local tourism boards validate event calendars to confirm peak pricing windows.
