Understanding this shift provides valuable context for planning and preparation.
-
Dew Point and Comfort Levels
The dew point, a measure of atmospheric moisture, rises in April, often exceeding 70F (21C). This increase contributes to a perception of increased mugginess, as the air feels heavier and less refreshing. Higher dew points can make strenuous outdoor activities feel more challenging, as the body’s ability to cool through perspiration becomes less efficient. Visitors should consider this factor when planning physical excursions.
-
Rainfall Potential
While April is not the wettest month in Key West, the increasing humidity creates conditions more conducive to rainfall. Although showers are typically brief and scattered, the chance of precipitation increases compared to the preceding dry season months. Visitors should be prepared for occasional rain showers and pack accordingly. The increasing humidity contributes to the development of afternoon thunderstorms, a common occurrence in the Florida Keys.
-
Impact on Perceived Temperature
Elevated humidity levels can make the air feel warmer than the actual temperature. This phenomenon, known as the heat index, combines temperature and humidity to reflect the perceived temperature by the human body. Visitors should consult the heat index, rather than solely relying on air temperature, to accurately gauge how warm it will feel outdoors.
-
Influence on Nighttime Temperatures
The increased humidity in April also influences nighttime temperatures. While evenings remain pleasant, the higher moisture content in the air prevents temperatures from dropping as significantly as during the drier months. This can impact sleeping comfort for visitors not accustomed to higher nighttime temperatures and humidity.
The increasing humidity in April signifies Key West’s transition into its wetter season. This rise in atmospheric moisture, while contributing to occasional rainfall and influencing perceived temperatures, remains an integral part of the island’s subtropical climate. Recognizing this aspect of April weather allows visitors to prepare adequately and adjust their expectations accordingly, ensuring a comfortable and enjoyable experience.

This transitional period presents a unique blend of favorable weather conditions alongside subtle shifts that signal the approaching wet season. The dry season, typically extending from November to April, experiences lower humidity, minimal rainfall, and consistent sunshine. April, however, begins to exhibit characteristics indicative of the impending shift. Increased humidity, though not yet at its peak, becomes more noticeable. Afternoon showers, though generally brief, become more frequent compared to the preceding dry months. This transition is driven by the northward migration of the Intertropical Convergence Zone (ITCZ), a low-pressure belt characterized by increased convective activity and precipitation.
The significance of this dry season transition lies in its impact on various aspects of Key West’s environment and local activities. For instance, the gradual increase in humidity contributes to more vibrant vegetation, as plants respond to the increased moisture in the air. The warming ocean temperatures, combined with higher humidity, create ideal conditions for the aggregation of certain fish species, attracting fishing enthusiasts and influencing local fishing practices. Furthermore, this transition period often offers a sweet spot for tourism. The weather remains predominantly dry and sunny, suitable for outdoor activities, while the crowds typical of the peak dry season begin to thin, offering a potentially more tranquil experience.
Understanding the nuances of this dry season transition equips visitors with the knowledge needed to prepare effectively. Packing for a range of conditions, including occasional rain showers, becomes essential. Awareness of the increasing humidity allows visitors to anticipate its impact on perceived temperature and plan accordingly.

This transitional phase presents a unique blend of attributes, influencing various aspects of the island’s environment and shaping visitor experiences. The dry season’s legacy manifests in the form of relatively low rainfall and abundant sunshine.
