Our take: May in Honolulu is genuinely lovely—think warm days around 24°C with afternoon showers that cool things down beautifully. You'll get plenty of sunshine (13 hours daily) perfect for beach time, though pack a light rain jacket since showers pop up regularly. The sea's a comfortable 25°C, ideal for swimmers who don't want intense heat.
