Site-specific forecast
Temperature, wind, precipitation timing and intensity for your venue address during your event window. Not your zip code. Your address.
Coval delivers a site-specific weather briefing for your outdoor wedding — built by a dedicated forecasting team, scoped to your ceremony window, with a clear go/no-go recommendation. One time. $200.
Coval is an operational weather intelligence firm based in San Antonio, TX. We build forecasts for construction, insurance, schools, and events — not consumer weather apps.
The forecast said 40% chance of rain on Monday. By Wednesday it was 70%. Thursday morning it dropped to 30%. Your mom is texting you screenshots from a different app that says thunderstorms.
You're comparing Weather.com to AccuWeather to Dark Sky, and they all say something different. Your venue coordinator says "we'll figure it out day-of." Your photographer says she's shot in rain before. Neither of them is a forecaster.
Meanwhile, you need to decide: Do you rent a tent? Move the ceremony inside? Tell your florist to waterproof the arrangements? Every option costs money, and the forecast changes every time you look at it.
Here's the thing nobody tells you: consumer weather apps aren't built for this. They're built to tell you whether to carry an umbrella — not whether to spend $4,000 on a last-minute tent for 150 guests.
Weather apps report a probability of precipitation for a broad area — usually a county or metro zone. They don't know where your venue is relative to terrain, water, tree cover, or microclimates. They don't know your ceremony is at 4pm and your cocktail hour moves inside at 5:30. They don't know you can tolerate a 20-minute shower at 2pm but not sustained rain from 3 to 6.
"60% chance of rain" doesn't mean it will rain for 60% of the day. It doesn't mean there's a 60% chance your ceremony gets wet. It means that across the entire forecast area, 60% of the time this atmospheric setup occurs, measurable rain falls somewhere in that zone.
That's not actionable. You need someone who looks at your specific site, your specific time window, and the current model data — and tells you what's actually going to happen at your venue during your ceremony.
A written weather briefing from the Coval forecasting team, built specifically for your wedding. Not a forecast pulled from an app. Not a county-level outlook. A briefing scoped to your venue, your date, and your decision.
Temperature, wind, precipitation timing and intensity for your venue address during your event window. Not your zip code. Your address.
A clear recommendation on whether your outdoor plans should proceed, and what to watch for if conditions are marginal. The kind of call you can actually act on.
If you're choosing between a tent, moving inside, or staying the course, we'll tell you which option the weather supports. We'll explain our reasoning so you can brief your coordinator and vendors with confidence.
No jargon, no probability ranges to interpret. Written for someone making a decision, not someone studying weather models.
Click the button, pay $200 through Stripe, and you're booked. Takes 30 seconds.
Right after checkout, you'll land on a short form: venue address, ceremony date and time, what decisions you're facing (tent, indoor backup, timing adjustments). Takes 2 minutes.
The Coval forecasting team analyzes current model data, radar trends, and local conditions for your specific site and time window. No automation. No AI-generated forecast. We deliver a written briefing to your inbox — typically within 24 hours of your request, and no later than 24 hours before your event. Clear recommendation. Plain English.
It's not a forecast — it's a decision briefing. You're spending $25,000+ on a wedding that depends on weather. A last-minute tent costs $2,000–$6,000. An unnecessary tent costs the same. $200 to know which call to make is the cheapest insurance in your wedding budget.
The sweet spot is 2–4 days before your wedding. That's when forecast models are accurate enough for site-specific guidance but early enough for you to act on the recommendation. You can submit your request up to 2 weeks out — we'll deliver the briefing at the right time.
If conditions shift meaningfully after delivery, we'll send an update. The briefing isn't a snapshot — it's a commitment to getting your call right.
You can, and you probably already are. The problem is that weather apps disagree because they use different models, different update cycles, and different interpolation methods — and none of them are looking at your specific venue. Averaging bad inputs doesn't produce a good answer.
The Knot and similar tools pull automated forecasts from the same data feeds as every other weather app. No human reviews them. No one adjusts for your location, your timing, or your decision. Coval briefings are built by a forecasting team that looks at the actual data for your site.
Weather is inherently uncertain — no one can guarantee a forecast. What we guarantee is that our analysis is more rigorous, more site-specific, and more decision-relevant than anything you'll get from an app. We explain our confidence level and what to watch for, so you're never blindsided.
Submit your venue, your date, and your decision. The Coval forecasting team will deliver a written briefing with a clear recommendation — so you can stop refreshing the app and start enjoying the week before your wedding.
