The answer to whether "first rain" is good is nuanced and depends on the context. It can be both beneficial and detrimental, depending on several factors.
Environmental Impact of First Rain
One significant aspect to consider is the environmental impact. The first rain of a season often washes away accumulated pollutants from the atmosphere, which have built up during drier periods. These pollutants, including toxins and materials, are carried by the rainwater. However, this first rain may itself contain high concentrations of these pollutants, making it potentially harmful.

Cultural and Personal Perspectives
There are also cultural beliefs surrounding the first rain. Some cultures associate it with healing properties, referring to it as "Agua de Mayo" ("water of May"). [Source: Reference mentioning "Agua de Mayo."] In other contexts, the first rain might simply be a welcome event, bringing relief from drought conditions and ushering in new growth for plants. For example, Taylor Swift's Eras Tour experienced a rain show, which she described as "SO MUCH FUN." [Source: Multiple Taylor Swift social media references regarding a rain show at her concert.] These instances highlight the positive, enjoyable aspects of experiencing first rain, focusing on the celebratory and emotional responses rather than the environmental effects.
Practical Considerations
Conversely, the first rain after a long dry spell can also pose risks. Roads may become dangerously slippery due to accumulated oil and grime mixing with the rainwater, making driving conditions hazardous. [Source: Reference mentioning road safety concerns after the first rain.] Therefore, caution is warranted during and after the first rain.
In summary, the "goodness" of first rain is subjective and depends heavily on the context. Environmentally, while it can eventually cleanse the atmosphere, the initial rainfall may be polluted. Culturally and personally, it can be viewed positively as a refreshing and even celebratory event. Practically speaking, it also presents potential hazards, particularly for drivers.
