January's numbers tell a specific story on the scorecard: a 78°F average high keeps conditions comfortable but sits at the cooler end of Kona's range — tied for the 2nd-coldest month of the year — which means the ball flies slightly shorter than it would in the warmer summer months. The 68°F average low matters most for early tee times, when morning rounds can feel genuinely cool for a Hawaiian island. Factor in 8.1 mph peak winds, the highest of any month here, and you'll notice pushback on approach shots into the trades, particularly on exposed lava-field holes.
The 19 precipitation days sound alarming until you realize that's actually the 3rd-driest month on the calendar in Kona. These are typically brief passing showers rather than course-closing rain, but 19 days is still more than half the month, so cart path conditions can be soft and fairway plugs are a real possibility. The 10°F daily swing — from 68°F at dawn to 78°F by midday — means layering up for the first few holes pays off, and club selection tightens as the air warms through the round.
Book morning tee times with the understanding that 68°F at dawn means a light layer is useful, but the trade winds tend to build through midday — so the very first slots after 6 AM can actually offer the calmest air of the day. With 19 precipitation days in the month, confirm a flexible cancellation policy; afternoon rounds face the highest odds of catching a passing shower.

January is marginally cooler and windier than December, dropping 1°F in the average high while peak wind climbs 0.6 mph and precipitation days increase by two. Compared to February, temperatures hold nearly identical — just 1°F warmer — but January has two fewer precipitation days, giving it a slight edge in course conditions. In practical terms, all three months sit in a narrow band; the difference between them is subtler than the month-to-month swings you'd find almost anywhere on the mainland.

It's workable but carries more variability than Kona's summer months. The 78°F average high is comfortable, but 19 precipitation days and the year's peak wind of 8.1 mph mean conditions shift more than the island's reputation suggests. Players who can tolerate an occasional shower and adjust for the trades will still get solid rounds in.
January is technically the windiest month of the year in Kona, though 8.1 mph peak wind is still within the site's 'moderate' threshold — not punishing, but consistently present. Courses built across open lava fields, which describes most layouts on the Kohala Coast, offer little shelter, so even a steady 8 mph headwind can shift club selection by one or two clubs on longer approaches.
