Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings February-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
