December is one of the most pleasant months to visit Panama City. As the dry season takes hold, the capital enjoys warm temperatures averaging 78°F (25.6°C), abundant sunshine, and significantly lower humidity than the rainy months.
Rain doesn't disappear entirely—brief, passing showers can still occur—but December marks the statistical low point for precipitation. You'll likely encounter clear skies most days, with warm evenings that rarely dip below the mid-70s. The Caribbean trade winds provide natural ventilation, making outdoor exploration comfortable.
This weather window makes December ideal for walking Casco Viejo's historic streets, visiting the Panama Canal's Miraflores Locks, or taking day trips to the San Blas Islands or Gamboa Rainforest. It's also peak tourist season, so expect higher prices and more crowds—book accommodations and tours well in advance.
Pack light, breathable clothing, a compact rain jacket just in case, and sun protection. The tropical sun is intense even when temperatures feel moderate.
