Kawaihae, HI Daily Water Report — August 31, 2026

Today in Kawaihae, diving enthusiasts have hit the jackpot with a stellar 9.3 out of 10 suitability score. The conditions are near perfect for exploring underwater, thanks to gentle winds and calm seas. The water temperature is a comfortable 28.3°C, with minimal wave action at 0.46m and a swell of 0.36m at a leisurely 9.95 seconds, making for a smooth dive experience. Boaters and kayakers also have a great day ahead, each scoring 8.4 out of 10. The light winds, peaking at just under 5 knots, offer a peaceful ride for both activities. The marine forecast shows the calmest waves around midnight, but conditions remain favorable throughout the day with no sign of rain. Fishing is a solid choice today with a 7.9 out of 10. The best chance to reel in something special might be during the solunar major periods from 01:48 to 03:48 and again from 13:48 to 15:48. The tides are moderate, with a low at 12:16 offering a potential window for shoreline casting. Surfers might find the waves a bit underwhelming with a 6.7 out of 10, as the swell direction and size aren't quite delivering the punch needed for exciting rides. However, the consistent swell and gentle winds might still provide some fun for longboarders or beginners. Looking back, today's conditions are a slight dip from yesterday's boating and fishing scores, but diving remains consistently excellent. As we move into the coming days, expect a slight rise in wind speeds, particularly by September 3rd, which could stir up the waters a bit. For those seeking the ultimate aquatic adventure today, diving is your best bet—it's a day to explore the vibrant underwater world of Kawaihae.
