NOAA NCEI (Climate / Degree-Days)

Live

NOAA NCEI historical climate records, climate normals, and heating/cooling degree-days (HDD/CDD) by station.

What is NOAA NCEI (Climate / Degree-Days)?

Access NOAA's National Centers for Environmental Information (NCEI) historical climate data through the keyless Access Data Service: daily summaries (temperature, precipitation), 1991-2020 climate normals, and heating/cooling degree-days (HDD/CDD) — the canonical driver of heating-oil, natural-gas, and power demand. Weather-normalize production and load, and model seasonal gas demand by region. Toggle on and use — no setup needed.
