Atlanta July 4 High Temp: Will It Hit 94-95°F?

Atlanta’s Fourth of July forecast is sitting at a crossroads. The city averages around 91°F on July 4, but the last few summers have pushed well above that baseline. The market currently prices a 94-95°F high at 33.5% probability. That’s the single most-traded outcome, but two-thirds of the money says it lands somewhere else.

The market question asks: what will the highest temperature in Atlanta be on July 4, 2026? The YES contract for 94-95°F sits at $0.34. The NO contract sits at $0.67. This market closes July 4, 2026, and total volume has reached $11,281.

How the 94-95°F Contract Works

YES pays out if Atlanta’s official high temperature on July 4 lands between 94°F and 95°F inclusive. The National Weather Service station at Hartsfield-Jackson Atlanta International Airport serves as the standard measurement point for official Atlanta high temperature records. Resolution follows the official daily maximum reading.

• YES (94-95°F): $0.34 per share, implying 33.5% probability. Pays if Atlanta’s July 4 high lands in this two-degree band.
• NO (94-95°F): $0.67 per share, implying 66.5% probability. Pays if Atlanta’s July 4 high falls outside this band, either above or below.

The NO contract collects whenever Atlanta’s high misses the 94-95°F band in either direction. That miss happens when a stronger heat dome pushes readings to 96°F or above, or when a cloud cover event, stalled front, or overnight thunderstorm keeps the high at 93°F or below. Atlanta’s July weather is notoriously volatile at the daily scale. Afternoon convective storms can shave four to six degrees off a high in a matter of hours.

Momentum and Market Signals

The trend score sits at 30.28, and the one-hour price change is flat. The market dropped 13% around July 2, which pushed the YES price from its open of $0.50 down to the current $0.34. That move tracks with updated forecast model runs. As the July 4 date came into the reliable forecast window, model consensus appears to have shifted toward temperatures above or below the 94-95°F band, rather than squarely in it.

Total volume is $11,281, all of it traded in the last 24 hours. Liquidity stands at $63,540. That liquidity depth is solid for a short-duration weather market. Volume below $1 million means price can swing sharply on a single updated forecast run or a new National Weather Service discussion. The 24-hour volume figure reflects genuine market activity as traders positioned ahead of the holiday.

• One-hour change is flat (+0.0%). The market has stabilized after the July 2 repricing. Traders are waiting on updated model guidance.
• The 13% drop on July 2 is the dominant signal. It reflects forecast models pulling away from the 94-95°F consensus as the event date closes in.
• Trend score of 30.28 confirms bearish momentum for the 94-95°F outcome. The composite signal favors a miss, not a hit.
• Liquidity at $63,540 is healthy for a 24-hour weather contract. Single trades can still move price meaningfully given the volume scale.
• Competing outcomes matter here. The 96-97°F and 92-93°F bands are the most likely alternatives if the 94-95°F contract misses. Any price action in those bands signals where forecast confidence is moving.

Lines Analysis: Atlanta Heat on the Fourth

The National Weather Service Atlanta forecast office issues hourly updated discussions in the 48 hours before a high-impact weather day. July 4 qualifies as high-impact because of outdoor event density. The current market price suggests that as of July 3, model consensus has not locked in on the 94-95°F range. Atlanta sits under a typical summer ridge pattern in early July, but ridges shift. A 500mb height anomaly even 100 miles to the west or east moves Atlanta’s high by three to five degrees.

The opposing scenario is real. A persistent upper-level high centered directly over north Georgia pushes Atlanta toward 96°F or above. That scenario reprices the 96-97°F and 98-99°F contracts sharply higher and kills the 94-95°F payout. Alternatively, afternoon clouds and a sea-breeze boundary pushing up from the south can cap the high at 92-93°F. Both outcomes have happened on recent Atlanta July 4 dates. The spread of possible outcomes is wide, which is exactly why the market prices NO at 66.5%.

• National Weather Service Atlanta model output is the single most important update before market close. Any shift in the Day-1 forecast cone moves price directly.
• GFS and European model agreement on the 850mb temperature plume signals whether the high tracks above or below 95°F.
• Afternoon convective initiation timing is critical. Early storms before 3 PM cut the high. Storms after 5 PM do not.
• Dew point readings on the morning of July 4 set the baseline for how quickly Atlanta heats. A dew point above 70°F suggests a stickier, hotter afternoon.
• Any updated NWS excessive heat watch or advisory for the Atlanta metro would confirm temps trending toward 96°F or above, moving volume to higher bands.

Total volume of $11,281 reflects serious engagement for a single-city, single-day weather market. The data favors the NO side, not because 94-95°F is impossible, but because a two-degree band is a narrow target in a city with high day-to-day temperature variance. Here’s what the measurements are telling us: the forecast window is open, and the next 12 hours of model runs will either restore confidence in the 94-95°F band or confirm the July 2 repricing was correct.

LEAN NO

The market data doesn’t care about the politics of Independence Day heat. A 13% price drop on July 2 and a trend score below 40 both confirm that updated forecast models have moved away from the 94-95°F band as the most likely Atlanta high on July 4.

What the market says: 33.5% probability means the market rates this a real but minority outcome. Volatility is high with the resolution date just hours away, and thin volume means a single large forecast update can reprice this contract sharply.

Key unknown: The National Weather Service Atlanta Day-1 forecast discussion, expected within the next 12 hours, is the single data point that will either restore the YES contract toward $0.40 or confirm the slide toward $0.25.
