Key West, Florida, experiences a transition in climate during October. This period marks the end of the hotter, more humid summer months and the beginning of a cooler, drier period. Average high temperatures typically range from the mid to upper 80sF (around 30-32C), while average lows fall to the low 70sF (around 22-24C). Rainfall decreases significantly compared to the summer, with October being one of the drier months of the year. Water temperatures remain warm, generally in the low 80sF (around 27-29C).
This shift in climate presents several advantages. The lower humidity and cooler temperatures create more comfortable conditions for outdoor activities. The reduced rainfall also makes it a more reliable time for enjoying the beaches and participating in watersports. Historically, October has been a popular time to visit Key West due to these favorable conditions. The decreased likelihood of hurricanes compared to earlier in the season adds further appeal.
