Race weather (wx) forecasts for IndyCar
Weather for Indycar test tomorrow on IMS road course: sunny, mild temps, very light winds
October 12, 2025 at 1:56 PM
Here’s your #MusicCityGP raceday weather briefing: a bit more cloud cover today, so ambient/track temps should be just slightly cooler than Saturday. Dewpoint temps (good indicator of humidity) in low-50s (that’s good)..so ‘it’s a dry heat’. Light winds from north-northeast. #IndyCar #INDYNXT
August 31, 2025 at 12:33 PM
No major forecast changes to make moving into the last race weekend of the #IndyCar season: upper-80s, dry, low humidity, northeasterly winds…and very similar conditions both days #MusicCityGP #Nashville
August 29, 2025 at 7:59 PM
Midweek #MusicCityGP forecast update: still looks good. Warm but dry weekend. Upper-80s, but comfortable humidity levels..so no “heat index” to add on top of these temps. Still have one eye on Sunday rain chances…but not a threat for now. #IndyCar #INDYNXT
August 27, 2025 at 10:59 AM
Early look at #MusicCityGP forecast: plan for mid-upper 80s. Humidity not too bad. Initial look appears dry, with better rain chances south…but way too early to lock that part in. #IndyCar
August 25, 2025 at 7:53 PM
Your raceday weather briefing for the #SnapOn250 at #MilwaukeeMile: cool northwesterly flow continues today…expect ambient temps near 70° for the #IndyCar race…breezy at times. Post-race: a few isolated showers may pop-up early evening, just something to be aware of for those still in the area late
August 24, 2025 at 12:15 PM
Here’s your Saturday morning weather brief: forecast tracking as previously described…early AM line of broken showers has moved through…clouds on back-edge should be lifting in next hour or so. West-northwesterly winds should get breezy by qualifying. #IndyCar
August 23, 2025 at 11:37 AM
No major forecast changes: front moves across Wisconsin Friday…won’t have too much moisture to work with but best shot for shower is overnight/early Sat…worth monitoring due to that early schedule for the first practice session. Sunday still the cooler of the two days. #IndyCar #MilwaukeeMile
August 21, 2025 at 2:03 PM
Early look at the #MilwaukeeMile forecast: some rain to start the week then a shift to a drier pattern by Wed. Keeping an eye on a weak front late Friday with some potential showers…but for now Sat-Sun looks dry with great temps #IndyCar
August 18, 2025 at 12:03 PM
Heat cranks up today at #PortlandGP: Sat evening final practice hit 88° amb/117° track. That’s close to where we’ll start the #IndyCar GP today at mid-day (at least for ambient). Other races: INDY NXT 75-80° this morning; USF Pro 2000 & USF2000 94-96° later today.
August 10, 2025 at 1:11 PM
No major #PortlandGP forecast changes…was 82° Friday, warmer today, still expecting mid-90s Sunday. Earlier start time on Sunday will help #IndyCar avoid peak heat window…but a couple USF Pro Championship series races follow the GP and will be approaching the max temp that afternoon.
August 9, 2025 at 1:42 PM
Initial outlook to start the week still looks pretty good, so minor tweaks only to #PortlandGP forecast: yesterday’s showers have moved thru, lingering clouds early today w/mid-70s..then progressively warmer til mid-90s Sunday (upper-90s Monday!)..hydrate for raceday #IndyCar
August 7, 2025 at 1:16 PM
Here’s a first look at the #PortlandGP forecast: cloudy/showery weather Wed-early Thu..then dry but heating up Fri-Sun. Raceday temps potentially 10° above seasonal norms for early August. Humidity looks ok, so not expecting an excessive heat index to add on top of these temps. #IndyCar
August 4, 2025 at 8:24 PM
Current satellite loop…you can see the fog/stratus clouds walking back up Salinas Valley as it burns off…it’s getting there, just takes time #IndyCar
July 27, 2025 at 5:26 PM
Here’s today’s #JavaHouseGP forecast: similar to last couple days, mid-60s at start, clouds decreasing, winds increasing. If you’re wondering if moving warm-up from this morning to yesterday was the right call..it was..regional airports reporting ceilings 500-700’ again this morning #IndyCar
July 27, 2025 at 2:35 PM
Nothing new with the forecast since previous updates…right now clouds are overcast between 400-700 ft with visibility between 2-3 miles…some patches where it’s worse…but everything should be noticeably improved by the time we get to #JavaHouseGP qualifying #IndyCar
July 26, 2025 at 1:30 PM
Here’s the Laguna Seca forecast for #IndyCar this weekend: no surprises in this one. 50s to mid-60s. Breezy in afternoon. Only potential impact is extent of low-level marine layer clouds in early AM..could get slight delay to early sessions (i.e. prac 2, warm-up), if conditions are right.
July 22, 2025 at 11:06 AM
7 am radar check: forecast on track with rain ending. True back edge of system is still dropping thru Georgian Bay..so a couple small blips on radar to watch…may get some drops out of low clouds as they pass through…but heavy/steady rain is done. No lake breeze today..it’ll remain a north wind
July 20, 2025 at 11:25 AM
Here’s your Saturday #IndyTO weather: should be a little warmer today…we’ll see if we can get to 80 before clouds move in later…still looks like rain moves in late tonight, but exiting by early Sunday morning…so dry race expected Sunday #IndyCar
July 19, 2025 at 11:21 AM
Friday #IndyTO weather brief: great conditions today..north wind this morning but should get a weak lake breeze by #IndyCar practice this afternoon. Sat looks good too. Still keeping an eye on next rain chance late Sat, but for now looks like everything departs by early Sun morning.
July 18, 2025 at 11:45 AM
WED UPDATE: near 90° today in Toronto..cold front Thu, with rain exiting early PM..sets up exceptional weather Fri and Sat. Shifted timing of next system a little to the left..so added slight chance shower late Sat, with Sun rain chances favoring overnight/early AM for now #IndyTo #IndyCar
July 16, 2025 at 11:41 AM
For your planning considerations, an early look at #IndyTO weather: week starts with hot/humid temps..then front on Thursday would break the heat..and Fri-Sat would be exceptional. Question mark for now is timing/strength of possible system Sunday..I’ll keep you updated as we get closer #IndyCar
July 14, 2025 at 6:55 PM
Preview for Race 2 weather at Iowa Speedway tomorrow: a little warmer tomorrow afternoon, but with an earlier green flag time temps should actually be pretty similar to Race 1. Wind shift to the southwest…but not as breezy as today. #IndyCar
July 13, 2025 at 12:37 AM
Saturday #IndyCar weather: following yesterday’s rain, some patchy areas of dense fog have set up, mainly east of Des Moines…should burn off around sunrise…then transition to mostly sunny conditions with temps maxing out in low 80s. Northwest winds for the race.
July 12, 2025 at 10:31 AM
Sounds like we’re finished with track activity at Iowa today…and given the current radar, seems like a prudent decision….
