In which type of climate is a larger step recommended for deck design?

In snowy and rainy climates, a larger step is recommended for deck design primarily due to the need to prevent water accumulation and to accommodate the load of potential snow. A larger step provides better drainage by directing water away from the deck surface, reducing the risk of standing water that can lead to rot, mold, and structural weakening. Additionally, this design can account for the additional weight of snow, ensuring stability and safety during winter months.

Considering other climates, warmer climates may benefit from different design considerations focused on heat and sun exposure, while dry climates usually do not have the same concerns regarding moisture or snow load. Humid climates, while they face issues like mold and moisture, typically do not require larger steps to manage snow loads and precipitation in the same way that snowy and rainy climates do. Thus, the unique challenges posed by snow and significant rainfall in the designated areas justify the recommendation of a larger step for deck designs in those conditions.
