Truth or Consequences has a cool desert climate (Köppen "BWk") with three main seasons. The summer season from April to June is very dry and generally hot with large diurnal temperature variation, giving way in July to the monsoon season which remains very hot – and is more uncomfortable due to the hotter nights – but is much more humid as rainfall from thunderstorms is frequent. The winter season from October to March has pleasantly mild and sunny days and cold to very cold nights, with very occasional rainfall from extratropical cyclones.
