Kahului, located in the USA, is characterized by a tropical climate with pleasant warm weather throughout the year. The temperature here is remarkably stable: monthly averages range from 21.3°C in February to 25.2°C in September. Daytime highs usually fall within the range of 23.8°C - 28.0°C, while nights remain comfortably warm, with minimum temperatures from 18.8°C to 22.4°C, creating excellent conditions for visiting the city in any season.

One of the key features of the climate in Kahului is the very low rainfall. Only 1 to 3 mm of rain falls monthly, making this region quite arid. Although there is no clearly defined rainy season, a slight increase in precipitation (up to 2-3 mm) and the number of "wet" days (up to 10-14 days per month) is observed from December to April. In the remaining months, from May to November, about 1 mm of precipitation falls, and the number of rainy days ranges from 9 to 13. This combination of low rainfall volume and relatively frequent occurrence indicates that rains here are typically very light, brief, and do not cause inconvenience.

Overall, the weather in Kahului offers wonderful conditions for a holiday almost all year round. Travellers can count on a large number of sunny days and consistently warm weather, which promotes both relaxation and active exploration of local attractions and natural beauty.

The temperature regime in Kahului is distinguished by amazing stability and comfort year-round. The annual progression of average temperatures is very smooth: from 21.3°C in the coolest month, February, to 25.2°C in the warmest, September. This means the difference between the coldest and hottest periods is only about 4 degrees Celsius. Maximum daytime temperatures range from 23.8°C (February) to 28.0°C (September), and minimum nighttime temperatures range from 18.8°C (February) to 22.4°C (August). Thus, even in the "cold" months, pleasant warmth reigns here, and the concept of "winter" is quite nominal.

The summer months, covering the period from June to September, in Kahului are characterized as very warm and sunny. The average daytime temperature during this time holds steadily around 27-28°C, dropping to a comfortable 21.5-22.4°C at night. This creates ideal conditions for beach holidays and enjoying nature. The winter period, from December to March, also remains very mild. During the day, the air warms up to an average of 24-25°C, while nights remain pleasantly cool with temperatures around 19-20°C. Daily temperature fluctuations throughout the year are moderate, averaging 5-6°C between daytime highs and nighttime lows, ensuring comfortable conditions for both daytime activities and evening strolls.

Kahului exhibits a unique precipitation pattern. Despite the fact that it can rain throughout the year, the total amount is extremely low. The city can be described as quite arid, with average annual precipitation not exceeding a few millimetres per month. Snow does not fall here, given the tropical climate.

Although there is no strictly defined rainy season in Kahului, periods with slightly higher precipitation can be distinguished. For instance, February is the "wettest" month with an average figure of 3 mm of precipitation. During this month, as well as in March and April, the highest number of days with precipitation is observed – up to 14 days. However, even during these periods, the volume of falling moisture remains minimal. The driest months are from May to November, when only 1 mm of precipitation falls, while the number of rainy days varies from 9 (in June and August) to 13 (in May).

Precipitation in Kahului typically consists of light and brief showers or drizzle. Given the low total amount in millimetres alongside its relatively frequent occurrence (from 9 to 14 days per month), it becomes obvious that heavy downpours are a rarity here. Rather, these will be short-lived rains that quickly give way to sunny weather and do not significantly impact travellers' plans.

When planning a trip to Kahului, you should focus on light and breathable clothing suitable for warm tropical weather. Since the temperature here is consistently high year-round, the foundation of your wardrobe should consist of t-shirts, shorts, skirts, and sundresses made from natural fabrics such as cotton or linen. Don't forget swimwear, as the weather is almost always conducive to relaxing by the water. Given that the sun here is intense, be sure to take high SPF sunscreen, headwear (a hat or cap), and sunglasses.

Although the total rainfall in Kahului is minimal, rains, albeit light, can occur in any season, especially from December to April when the number of "wet" days reaches 10-14 per month. Therefore, a light waterproof windbreaker or a compact umbrella might come in very handy without taking up much space in your luggage. Evenings can be slightly cooler, especially compared to the daytime heat, so a thin sweater, cardigan, or light jacket will help you feel comfortable during evening walks. Comfortable shoes are your main ally: sandals or flip-flops for the beach, and light sneakers or loafers for walks and excursions.

The principle of layering is not as critical here as in regions with sharp temperature fluctuations, but having the option to throw a light long-sleeved shirt over a t-shirt or vest top can be useful both for sun protection and for extra comfort in air-conditioned spaces or during a light evening breeze. In general, your luggage for a trip to Kahului should be geared towards heat, sun, and relaxed leisure, with minor additions in case of brief rain.
