The annual range of average temperatures fluctuates from approximately 25.9°C in January to 29.7°C in May. The hottest months are typically April and May, when the average maximum temperature can reach 32.5°C - 32.8°C, and the average daytime temperature stays around 29.1°C - 29.7°C. The "coolest" months are considered to be January and February, with an average temperature of about 25.9°C - 26.4°C and minimum nighttime temperatures dropping on average to 23.6°C.

The relative "summer" period, covering the hottest months of April and May, is characterized by sweltering heat. April is often marked by dry heat, while in May, humidity increases noticeably, accompanied by more precipitation and rainy days. Daytime highs in these months consistently exceed 30°C, creating a sense of true tropical heat. Even in other months, which could be conventionally called "winter" (December–February), the weather remains very warm. Average daytime temperatures during this period rarely drop below 28°C, and nights remain comfortably warm, with temperatures around 23-24°C. Thus, Santa Rosa does not experience the sharp seasonal temperature fluctuations typical of temperate climates; rather, it has smooth transitions from a very warm to a hot season.

In the "cooler" month of January, these figures are about 28.2°C during the day and 23.6°C at night. This means that even after a hot day, the evenings and nights bring some relief without a sharp drop in temperature.

When planning a trip to Santa Rosa, keep in mind that a warm tropical climate awaits you year-round. Average temperatures fluctuate between 26°C and nearly 30°C, so your wardrobe should consist of light, breathable clothing made from natural fabrics like cotton or linen. Don’t forget high-SPF sunscreen, a hat, and sunglasses to protect against the bright sun, especially from January to April when rainfall is minimal and sunny days are most frequent.

The rainy season in Santa Rosa typically lasts from May to December, with the highest rainfall and most rainy days occurring from June to October. During this time, it is highly recommended to bring a light waterproof jacket or raincoat, along with a compact umbrella. Clothing made from quick-drying materials will be very useful. Consider waterproof shoes or sandals that handle moisture well, as downpours can be intense, though usually short-lived. Even during drier months like January, November, or December, a sudden shower is possible, so a light rain protection item may come in handy.

Regardless of the season, comfortable walking shoes are your best companion for exploring Santa Rosa. Although the weather is mostly hot, a light cardigan, shawl, or thin sweater may be useful for sun protection, in air-conditioned spaces (malls, restaurants) that might feel chilly after the outdoor heat, or for evening walks when temperatures drop slightly. Layering here is more for indoor comfort and sun protection rather than for keeping warm.
