Data-derived climate profile
How Waimea's climate pattern fits together
cooling led · low swing
Warm-season load persists through a relatively even calendar in Waimea. Cooling totals 3,604 degree days, more than double the 3 heating measure, and the 8.0°F seasonal range is compact rather than sharply divided.
A moisture-range label is withheld because Waimea's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
Temperature varies within a narrow 8.0°F band across the normal year. August and February mark the typical warm and cold ends of the calendar. The annual average is 75°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A frost-free growing-season length is not available for Waimea. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Waimea's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Waimea that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Waimea's primary station: WAIMEA 947 (USC00519629). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The exact name-and-state crosswalk returns more than one Census place, so PlainClimate leaves the place identity unresolved. Because Waimea hits multiple Gazetteer rows, PlainClimate refuses to pick one and shows the unresolved badge instead of inventing a GEOID.
On this page every temperature, precipitation, and derived score for Waimea comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
