Short answer: light rain is playable with the right gear. Steady rain makes scoring much harder. Lightning or heavy rain means stop immediately. Our score treats rain probability as a linear penalty — 100% chance of rain removes 40 points from playability.
| Rain Probability | Playability |
|---|---|
| 0–20% | Ideal — plan on dry conditions. |
| 20–40% | Chance of rain — pack rain gear. |
| 40–60% | Risk — expect showers during your round. |
| 60%+ | Rain likely — consider rescheduling. |
Stop for lightning immediately — no round is worth it. Heavy rain that pools on greens is also a stop signal; casual water rules make play slow and scoring essentially random. Our playability score caps rain penalty at 40 points, which typically pushes any day with 60%+ rain into the "Poor" tier.
