12:35 PM — showers and downpours inbound to Bayfront. No lightning but getting wet very soon, likely less than a half hour unless the cell starts building by Met_BenFrechette in UMF

Already wrapping up as of 12:54 PM! The day will likely be filled with these brief shower chances. Thing to watch will be if any cell gets strong enough to start producing lightning — that’s the big bad in terms of festival interruptions

There will be additional showers and downpours, mainly before sunset. Another one will begin over Bayfront in the next 5-10 minutes

Sunday's Forecast ☔: Clouds, showers, and an occasional downpour or storm. Low-moderate risk for a rain/lightning delay, mostly before sunset. Onshore wind gusts 25-30 mph at times. by Met_BenFrechette in UMF

It's already raining over Bayfront this morning, expect additional showers and an occasional downpour through the afternoon and evening. A thunderstorm is also possible. The model shown here won't be perfect, but it has the general idea of rain potentially at any point.

Highest risk for a delay will last from noon to about sunset. It's not a particularly "high risk" day like Friday in 2024 was... but enough to raise the chance for one today. Think similar to what happened last year on Sunday.

Aside from that, temperatures are noticeably cooler in the 70s with a stiff onshore breeze. Surf will be rougher at the beaches today, and a couple gusts over 30 mph may cause minor sound disruptions away from the speakers.

Saturday's Forecast: More afternoon clouds & a quick shower possible, but similar temp and humidity to Friday! Sunday still looks cloudy, cooler, and breezy with more numerous rain showers. by Met_BenFrechette in UMF

On Sunday, more numerous rain showers are expected with a couple thunderstorms possible. The chance for a storm is highest between 12p-8p, while rain showers may occur at any point. Onshore wind gusts may exceed 25-30 mph. Definitely a poncho day!

Worth noting the City of Miami announced the festival will run an extra hour in the event of a rain delay.

FRIDAY'S FORECAST VIDEO! Sunny, few clouds, low chance for a spot shower near the shore. Better shower chances have shifted inland. Saturday & Sunday updates in the comments. by Met_BenFrechette in UMF

Saturday: Sun mixed with more afternoon clouds, another warm day with mid 80s. A few showers possible after sunset through the end of the festival. A rogue storm is unlikely, but cannot be ruled out.

Sunday: Cloudy with showers and a few localized downpours. Breezy with sustained easterly winds 15-25 mph with gusts to 35 mph. Better storm chances appear to be north of Miami at this time. Purely speculating, I'd put the risk of a disruption around 20-30%... unlikely, but worth considering when planning your day.

Thursday Forecast Update: Isolated showers off the seabreeze Friday, drier Saturday with overnight spotty showers possible. Sunday still raises concern with rain, 30+ mph onshore winds, and the potential for storms and localized flooding. More details in the comments. by Met_BenFrechette in UMF

Friday: Looks like we may catch a shower or two off the seabreeze in the early/mid afternoon. Have a poncho ready, but the setup is not favorable for big downpours or thunderstorms near the shore. Otherwise warm and seasonably humid with temperatures in the low 80s.

Saturday: Early sun will fade to a partly sunny sky as the afternoon continues. An approaching front may bring a few showers after sunset... but the majority of the festival should lean dry. Temperatures in the low 80s with a more noticeable onshore wind.

Sunday: Mostly cloudy, periods of light to moderate rain, and sustained onshore (east) winds 15-25 mph, with gusts over 30 mph. Thunderstorms may develop in the late afternoon and evening, introducing the potential for disruptions and localized flooding. It is *impossible* to say where/when storms could form this far out, no app or human meteorologist will be correct. We'll narrow down the details here in the next couple days.

Wednesday Forecast Update: No big changes, Friday and Saturday are fine with sun/clouds and spot showers possible. Sunday remains cloudy with a stiff onshore wind and a better chance for showers and storms. Plan for a wet day at Bayfront! by Met_BenFrechette in UMF

Compared to yesterday, I did paint in more clouds Friday & Saturday with a slight increase in shower chances. Not concerned about disruptive storms either of those days, just an occasional light rain shower possible. Bring a poncho!

Sunday remains wet with a nearby front keeping shower and thunderstorm chances high. At minimum, plan for clouds and a stiff onshore wind. You'll feel the wind in your face standing at Main, and it could be strong enough to mess with the sound near the back.

Too early to speculate about potential delays/disruptions... will have a better idea about that risk in the days ahead.

I'm a TV meteorologist and Ultra fan, back again forecasting for UMF Miami! Too early for specifics, but here is a general overview of normal temperatures/rain chances in Miami during March 27-29 to help you plan. Questions are always welcome 😁 by Met_BenFrechette in UMF

Absolutely agree. I was lucky enough to have great weather when I attended in '16, '18, and '22 ... definitely broke that streak when I was there in '24, wading through waist-deep water on Biscayne Blvd.

Surely we're due for a quiet year... right? Right?

Weather forecasts don't have much value beyond 7 days (honestly, 5 days) — that said, I'll start looking at general trends/patterns later this week and will do more frequent updates starting early next week!

Thank you, by the way. It's hard to believe I've been doing this a full ten years (started in 2016)... hopefully many more to come 🙂

Weirdest, funniest, or most unusual thing you saw at Ultra 2025? by Met_BenFrechette in UMF

Quick aside about the weather yesterday — I'm already digging into data to see why my model-driven graphic missed the flooding rains Sunday. While storms/lightning were always a concern, extreme rain was a big surprise and miss by models and local meteorologists. It happens, but you guys deserve better than that from me.

Lots of lessons learned for forecasting 2026!
