If you're deciding on Kona for 2026-08-29 – 2026-08-30, start with the numbers, then the plan.
Should you plan around Kona's forecast this weekend?
Kona, Hawaii
Weekend air in Kona sits near 82°F / 75°F, plus a workable rain total around 0.35 in — enough to decide whether the trip is on.
Treat Kona as the whole trip: build the day around dry heat and open sky, then fill gaps with the local picks below.
If the numbers still look good by Friday, lock the plan around 82°F — not a vague “nice weather somewhere.”
