Kapaa welcomes travellers with a mild and pleasant tropical climate, ideal for a holiday at any time of year. An atmosphere of eternal summer reigns here: the air temperature is enviably stable, fluctuating smoothly within a comfortable range of 21°C to 25°C on average. Thanks to this, there is no exhausting heat or piercing cold in the city, making it a perfect place for those seeking weather balance.

There is no distinct change of seasons here in the usual sense. The difference between the "coolest" month, February, and the warmest, September, is only about 4 degrees. Precipitation falls quite regularly throughout the year: the number of rainy days varies from 13 to 23 per month. However, these are often light, refreshing rains that pass quickly, leaving freshness behind and maintaining the region's lush greenery.

A characteristic feature of the weather in Kapaa is its predictability. High humidity and frequent but low-volume precipitation create a unique microclimate. When planning a trip, it is worth being prepared for frequent variable cloudiness and short-term rains, so a light raincoat might be useful even in the warmest months, such as August or September.

The climate in Kapaa is distinguished by amazing stability and mildness, making this city an attractive travel destination year-round. Sharp seasonal contrasts are practically absent here: the annual temperature range varies within very comfortable limits. February is considered the "coolest" month with an average of about +21°C, while the peak heat occurs in August and September, when the air warms up to an average of +25°C.

The summer period, which lasts quite long here, is characterized by pleasant warmth without extreme heat. From June to October, daytime temperatures reach +26…+27°C, creating ideal conditions for beach holidays and water sports. Winter in Kapaa feels more like a mild spring: even in January and February, the thermometer rarely drops below +20°C, allowing tourists to enjoy walks and nature without the need to bundle up in warm clothes.

A feature of the local temperature regime is the minimal difference between daytime and nighttime readings. The fluctuation amplitude is only 3–4 degrees: if during the day the air warms up to +24…+27°C, then at night the temperature remains at the level of +20…+23°C. Such stability guarantees comfortable warm evenings at any time of year, saving travellers from surprises in the form of sudden night cooling.

Precipitation in Kapaa falls exclusively as rain, as the air temperature remains warm and comfortable year-round, excluding the likelihood of snowfall. A characteristic feature of the local climate is the high frequency of precipitation with extremely low volume. This indicates that rains here are usually light drizzle or very short-lived sun showers that end quickly and do not create puddles.

Interestingly, the concept of a "rainy season" is quite blurred here, as wet days are distributed throughout the year. However, statistics show that spring and summer are periods with the most frequent precipitation. The peak falls in July, when about 23 rainy days are recorded, and April with 22 days. Despite the high frequency, the total precipitation level in these months remains at 2 mm, confirming the light nature of the rains.

The least rainy period in terms of precipitation frequency can be called winter. The "driest" month is January, when the number of days with precipitation drops to 13. At the same time, in winter months (December, February), as well as in March and April, the average volume of precipitation increases slightly to 3 mm. Travellers should be prepared for frequent weather changes, but serious prolonged downpours, judging by the data, are uncharacteristic for Kapaa.

When heading to Kapaa, rely on light summer clothing made from natural fabrics such as cotton or linen. Since the air temperature delights with stability and stays in the comfortable range from +20°C to +27°C throughout the year, shorts, T-shirts, and light dresses will form the basis of your wardrobe. Don't forget comfortable footwear: open sandals or flip-flops are perfect for the beach and city walks, while reliable closed-toe trainers will come in handy if you decide to explore the picturesque nature trails of the surroundings.

Despite the generally warm climate, statistics show a large number of rainy days (sometimes more than 20 per month), so a light raincoat or a compact windbreaker are must-haves in your suitcase. Precipitation is often short-term, but moisture protection will definitely be needed. It is also extremely important to take care of UV protection: bring sunscreen with a high SPF factor, quality sunglasses, and a hat, as the sun is active here even with variable cloudiness.

For evening walks or early morning outings, we recommend using the layering principle. Bring a thin jumper, cardigan, or hoodie to feel cozy when the temperature drops to minimum values around +20°C. And, of course, do not forget swimwear — the ocean in Kapaa beckons travellers year-round, regardless of the season.
