April 4th in Ala Moana sits right in that sweet spot of Hawaiian spring — 56 years of data put the average high at 83° with a low of 68°, about as comfortable as it gets. There's a 39% chance of rain, though in Honolulu that usually means a quick shower rather than a washed-out day.
Ala Moana's all-time temperature range is surprisingly narrow for a major city — just 54 degrees separates the record high of 97° (September 2019) from the record low of 43° (January 2009). The real extremes here come from rain: a single December day in 1967 dropped 8.21 inches on the neighborhood.
Honolulu barely flinches across the seasons — monthly highs span just 7 degrees, from 81° in January to 88° in August and September. If you're chasing peak warmth, aim for mid-July through September; if you want to dodge the rain, skip late December, which averages over an inch of precipitation in its final week alone.
