Recent forecast models from regional meteorological agencies show a high likelihood of daytime maxima reaching 31–32°C in Panama City on May 18, driven by typical early wet-season conditions with moderate humidity, light easterly winds, and afternoon convective clouds that often limit further warming. Historical May climatology places average highs near 31.5°C, with rare excursions above 33°C under clear, dry spells. Current ensemble guidance indicates stable steering patterns and no strong subsidence to suppress cloud development, keeping the 33°C-or-higher outcome at modest implied probability. Updated model runs and local observations expected later today could refine these ranges ahead of market resolution.
