Labor Day falls on Monday, September 7 this year, which makes this the last long weekend of summer for most of the US — and the forecast for it splits the country in half. Some regions are heading into a genuinely pleasant few days; others are looking at triple-digit heat, tropical downpours, or both. Here’s the region-by-region breakdown, and what it means if you’re still deciding where to go.
Where It’ll Be Too Hot to Enjoy
Parts of the Southern and Central Plains, including Iowa, are forecast to sit in the triple digits through the entire holiday weekend, with dangerous heat index values layered on top. If your trip involves being outdoors for extended periods — hiking, a lake day, a stadium — this is the region where that plan needs a backup indoor option, and where hydration and timing (mornings and evenings, not midday) matter more than usual.
Where Rain Could Wash Out Plans
A system is expected to move through the Ohio Valley and mid-Atlantic on Saturday, and Sunday looks like the roughest day for outdoor plans across the Southeast, with the risk of thunderstorms. Two cities stand out in the forecasts: Miami, with an 85% chance of rain, and Seattle, at 81% — both a coin-flip away from a washed-out weekend regardless of what else is on the itinerary there.
The Southwest’s Hidden Risk
Away from the obvious rain forecasts, the Southwest carries a quieter but more dangerous risk: moisture pulled north from Hurricane Marie is raising flash flood potential in the region over the holiday weekend. This is the same hazard — sudden water in places that look dry — covered in more detail in our guide to flash floods in desert canyons: never drive into water of unknown depth, and treat a flash flood watch as a reason to change plans, not a footnote.
The Best Bet This Weekend: The Northeast
If the forecast is still steering your destination rather than your dates, the Northeast is the one region coming through this weekend with drier weather and genuinely pleasant temperatures — the closest thing to a safe bet on the current national map.
A Quick Checklist for This Weekend
- Check the local forecast for your specific destination the morning you leave, not the day you booked.
- In the Southern and Central Plains, plan outdoor time for early morning or evening and have an indoor fallback.
- In Miami, Seattle, and the wider Southeast, build a rain-day plan into a coastal or beach trip rather than assuming it will hold off.
- In the Southwest, treat any flash flood watch as a reason to reroute, not wait out.
- If your trip touches the Gulf or Atlantic coast at all this month, our hurricane season travel guide covers how to read NHC watches and warnings and time travel insurance around a storm.
None of this rules out travel this weekend — it just means checking the actual regional forecast is worth five minutes before locking in where you’re headed for the last long weekend of the season.
