Rams vs 49ers at the MCG: what the weather actually did
The NFL's first regular-season game in Australia drew the calmest hand Melbourne had to offer: dry every hour, air at 11–14°C, and wind under 5 mph. Weather was a non-event, and the 49ers won 27–7. This page keeps the recorded game-time conditions, the ten years of Melbourne September climate we published beforehand, and what those numbers did — and did not — do to kicking.
Recorded conditions at the MCG
| Temperature at kickoff (10:35am) | 11°C / 52°F |
| Rain in the game window | 0.0 mm |
| Wind speed | 1–8 km/h (under 5 mph) |
| Kicking penalty from conditions | None |
| Final score | 49ers 27, Rams 7 |

What Melbourne does in mid-September
Ten seasons of hourly reanalysis at the MCG (Open-Meteo ERA5, 5–17 September 2016–2025; 130 days, 520 hours in the 10am–1pm kickoff window).
| Average temperature, 10am–1pm | 14.9°C / 58.8°F |
| Hours with measurable rain, 10am–1pm | 27% |
| Days with ≥1 mm rain | 45% |
| Average wind speed, 10am–1pm | 18.5 km/h / 11.5 mph |
| Hours above 30 km/h wind | 9% |
| Warmest / coldest daily max | 24.0°C / 10.5°C |
The short version for an American audience: something like a cool, breezy Seattle morning in October. Mild rather than cold, showers more likely than not somewhere in the day, and a breeze that is real but rarely severe. Game day landed on the quiet end of that distribution — dry and almost windless — which is worth remembering the next time a single game gets read as proof about a venue.

One MCG-specific caveat: the ground is enormous and ringed by tall continuous stands, so wind measured in the city arrives at surface level broken up and swirling. We discount raw wind here rather than treating it as a clean end-to-end advantage. The temporary NFL field is laid across the oval, which means a crosswind on the city forecast does not map neatly onto a crosswind between the posts.

The Rams play home games indoors at SoFi Stadium. The 49ers play in the mild, dry Bay Area. Neither roster gets regular reps in cool, damp, breezy football. Our NFL Climate Shock research tracks exactly this pattern — dome and warm-climate teams moving into colder, windier outdoor conditions — and found a consistent scoring drag in the games that clear the threshold. Melbourne in September is a mild version of that shift, not an extreme one: the temperature gap is real, the wind gap is modest.
Read the NFL Climate Shock studyTwo very different travel plans
Travel and body-clock context — not part of our weather read, and no lean attached.
The 49ers left San Francisco on 2 September and landed in Melbourne on 4 September, about a full week before kickoff, specifically to give players time to adjust to the time difference. General manager John Lynch has said the club consulted sports scientists and sleep experts before settling on that plan.
The Rams are taking the opposite route: arriving roughly 24 hours before kickoff and staying as close to Pacific time as possible rather than attempting to shift. Sean McVay has been notably secretive about the exact itinerary.
Kickoff is 10:35am Friday AEST, which is 5:35pm Thursday Pacific time. That matters: on an unshifted Rams body clock, the game falls in late Thursday afternoon — a normal, even favourable time to play, not the overnight hours a "don't adjust" strategy would usually risk. It reads as a deliberate scheduling angle rather than a shortcut.
What the science actually says
Melbourne is 17 hours ahead of Pacific time, but circadian researchers typically model jet lag using the shorter direction around the clock: 24 minus 17 is 7. So the trip functions more like a roughly 7-hour westward-style delay than a 17-hour eastward advance, even though the flight itself travels west across the Pacific.
That distinction has evidence behind it. A 10-season study of 11,481 NBA games found eastward jet lag was associated with a real — though only marginally significant — drop in home-team performance, while westward jet lag showed no measurable effect on performance or game outcome at all, home or away. If this trip behaves like the westward-style shift, the expected impact is smaller than the "17-hour time difference" framing implies.
Honest limits: there is no historical precedent for this exact scenario. It is the first NFL game in Melbourne and the first regular-season game to cross the international dateline, so this is informed context, not a tested prediction. We are not claiming to know which approach is better — both are defensible and evidence-informed, and both avoid the same known risk of partial adjustment, which the research treats as the worst-case middle ground. As small-sample real-world context, the Rams have reportedly performed well in previous international games under McVay using a similar approach.

Frequently asked
Did it rain for the NFL game at the MCG?
No. Not a millimetre fell in the kickoff window: the hours from 10am to 1pm AEST on Friday 11 September 2026 recorded 0.0 mm at the MCG. That was the better half of the odds — Melbourne in mid-September records measurable rain on roughly 45% of days (2016–2025, Open-Meteo reanalysis at the MCG), and about 27% of hours in that window see at least 0.1 mm.
Is the MCG covered or does it have a roof?
No. The MCG is fully open air. Every ball kicked is exposed to the conditions, though the tall continuous stands shelter the surface and break wind up rather than letting it run cleanly end to end.
How cold was it at kickoff?
Mild. Temperature rose from about 11°C (52°F) at 10am to 14°C (57°F) by 1pm AEST — near the cool end of the ten-year range for that window (roughly 11.5–19°C) but nowhere near cold enough to suppress the ball.
Did wind affect field goals at the MCG?
No. Recorded wind ran between about 1 and 8 km/h (under 5 mph) through the game window, well below the roughly 10 mph sustained point where our kicking model starts penalising long attempts. That is unusually still for the MCG, where the ten-year average in this window is 18.5 km/h and 46% of hours exceed 20 km/h.
How does this compare to a Rams or 49ers home game?
SoFi Stadium is covered and Levi's Stadium sits in a mild, dry Bay Area climate. Neither team plays regular home football in cool, damp, breezy conditions. That travel-into-unfamiliar-conditions pattern is exactly what our NFL Climate Shock research tracks.
