The temperature in Kauai generally averages at a comfortable 78 degrees Fahrenheit regardless if you’re visiting in the summer or winter months. The hottest and coldest seasons will only cause temperature to rise or drop by 5 to 6 degrees. Water temperature ranges between 74 to 80 degrees Fahrenheit. Temperature does tend to drop early in the morning and in the evenings.
Kauai plan should include rain as well since there is a lot of it in the island. From December to March, expect hard rain showers so hiking and other water activities can be affected. You can enjoy better weather in the summer. The northeast side of the island is the one most affected by rain so you might enjoy the weather more on other ends. Heavy showers however, provide the advantage of having bigger and better flowing waterfalls and healthier vegetation.
What to Bring in Kauai
Include some of the most essential items in your Kauai plan to ensure a comfortable visit. Sunscreen or sunblock lotion is important preferably waterproof ones with an SPF of at least 25 to 30 since the sun can be intense at the beach. Bring sunglasses as well to protect your eyes from UV rays. Don’t forget a camera with a lot of memory or film to capture fun moments and captivating sights. Temperature does not go into the extremes in the island so bring comfortable clothes which you can readily hit the water in.
Other important items include a Kauai map that reveals the important highways and bypasses as well as popular tourist attractions. Bring a water jug when hiking and going deep into the island since rivers and streams may not always be safe to drink from. Mosquito repellents, hiking boots, beach games and water sports gear will keep the whole Kauai plan complete and enjoyable too.
