You're planning a gorgeous outdoor wedding. But what if it rains? Having a solid Plan B (and C!) means you'll enjoy your day no matter what the sky decides.
Size your backup in seconds: our free Wedding Weather Backup Planner works out the tent size you'd need for your guest count, estimates the 2026 rental cost, and tells you when to make the rain-or-shine call.
How Likely Is Rain?
Rain risk depends far more on where you marry than on a national average — Seattle, Miami and Phoenix have completely different calendars. The table is a rough pattern for much of the country; check NOAA climate normals for your town and date.
| Season | Rough Rainy Days/Month (varies by region) | Risk Level |
|---|---|---|
| January-February | 8-12 days | High (cold + wet) |
| March-April | 8-11 days | Medium-high (spring showers) |
| May-June | 7-10 days | Medium |
| July-August | 6-9 days | Medium (afternoon storms) |
| September-October | 6-8 days | Lower (best months!) |
| November-December | 8-12 days | High |
Pro tip: In much of the country, September and October are relatively dry and comfortable — but the Atlantic hurricane season runs June 1–November 30 and peaks from mid-August to mid-October, so Gulf Coast, Florida and Southeast couples need a solid Plan B (and wedding insurance) for fall dates, and the Pacific Northwest's rainy season starts in October.

| Day-of morning | Final adjustments only (minor repositioning) |
When to Call It (Move Indoors)
| Weather | Decision |
|---|---|
| 10% chance of rain | Proceed outdoors! (Have umbrellas ready) |
| 30-40% chance | Proceed but prepare backup (tent sidewalls ready) |
| 50-60% chance | Seriously consider activating Plan B |
| 70%+ chance | MOVE INDOORS or put tent up |
| Thunderstorms/lightning | ALWAYS move indoors (safety!) |
| High winds (>30 mph) | Move indoors (tent not safe!) |
| Light drizzle only | Can be romantic! Umbrellas + embrace it |
