While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. The climate in Key West during February can be summarized as warm, humid and reasonably dry.
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus. Weather data is prone to errors, outages, and other defects.

February's weather is exceptionally comfortable at Key West, Florida. In most years, Key West averages a daily maximum temperature for February that's between 74 and 78 degrees Fahrenheit (23 to 26 degrees Celsius).
In this report, we use a base of 50°F and a cap of 86°F. Half Here's our guide to the top things to do in Key West in February. The thin dotted lines are the corresponding average perceived temperatures. This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. By the end of the month, the temperature has climbed around 2 °F (1 °C) above what it was at the start. Home | Privacy & Cookies | Contact | About. Within 50 miles is also essentially flat (16 feet). Don't wait any longer to pack your bags. The shaded overlays indicate night and civil twilight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands. The percentage of time spent in various temperature bands. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. The average high temperature will peak at 74°F (24°C) while the average low temperature will hit a maximum of 64°F (18°C). The topography within 2 miles of Key West is essentially flat, with a maximum elevation change of 10 feet and an average elevation above sea level of 2 foot. This is the island's driest month and the temperatures are warm. For many, it's perfect. Daily high temperatures increase by 2°F, from 75°F to 77°F, rarely falling below 67°F or exceeding 82°F. From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night. The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than.
