Climate Insight: Ewa Kalaeloa, HI
An annual average temperature of 77°F, ranging from a mean daily high of 85°F to a mean daily low of 69°F is what the NOAA 1991–2020 climate normals report for Ewa Kalaeloa, Hawaii. August is typically the warmest month of the year, while January is the coldest. That baseline comes from station USW00022551 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Anyone planning to live, garden, or travel in Ewa Kalaeloa should weigh precipitation alongside temperature: the annual average runs 13.9 inches, predominantly as rainfall. Growing-season length varies with elevation and microclimate. And on the energy front, 0 heating degree days and 4,396 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Ewa Kalaeloa scores 67/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, August-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
