"Wind and weather permitting" is a commonly used phrase to indicate that something is subject to outside factors that cannot be controlled. There are several synonyms that could be used to replace this phrase, such as "subject to conditions," "contingent on circumstances," "conditional on atmospheric conditions," or simply, "weather-dependent." Other options could include "climate-sensitive," "wind-sensitive," or "weather-restricted." Depending on the context and application, some potential alternatives might include "weather-permitting," ".weather-prepared," or "wind-ready." However, regardless of the specific synonym selected, the underlying meaning and implication should remain consistent with the original phrase - that external factors beyond our control must be taken into account.
