Stable income: Somewhat stable

Beach gear rental businesses can provide a moderately stable monthly income for most people who try it. Based on online research and my own observations, many individuals earn consistently from this side hustle. While there may be fluctuations during peak versus off-peak seasons, overall, there is a decent baseline income to rely on. I'd rate it a 3 out of 5 because while it offers stability in earnings, there can still be some variability based on factors like weather and tourism trends.
