Miami June 22 High Temp: Will 92-93°F Hit?

Miami sits at the edge of its hottest stretch of the year. The 92-93°F bracket has climbed to 61.5% probability on Polymarket, driven by a 5% price jump on June 21 as traders locked in positioning ahead of tomorrow’s resolution. Here’s what the measurements are telling us: late June in South Florida is reliably brutal, and the atmosphere right now is delivering on that expectation.

The market question asks for the highest recorded temperature in Miami on June 22, 2026, resolving at noon Eastern. The YES contract for 92-93°F sits at $0.62. The NO contract sits at $0.39. Total volume is $10,566, all of it placed in the last 24 hours, with $54,754 in liquidity behind the order book.

How the 92-93°F Contract Works

YES pays out if Miami’s official high temperature on June 22 falls between 92°F and 93°F, inclusive. NO pays if the high lands anywhere outside that two-degree window. Resolution draws from the official Miami observation record. The contract closes June 22 at noon Eastern, so only the morning peak through that cutoff counts.

• YES (92-93°F): $0.62, implying 61.5% probability
• NO (any other reading): $0.39, implying 38.5% probability

The NO side wins if Miami overshoots or undershoots. A reading at 94-95°F or higher is the most plausible NO scenario, given the direction of current heat. Forecasters are tracking a ridge of high pressure over South Florida that tends to push afternoon highs above the 90-91°F baseline. If that ridge intensifies overnight, Miami clears 93°F and the NO contract at the 94-95°F bracket becomes the winner.

Momentum and Market Signals

The momentum composite here is straightforward. The trend score sits at 50.01, the 1-hour change is flat, and the 24-hour move is the story: YES jumped 5% on June 21 as weather model output aligned around the 92-93°F range. That single-day move from $0.46 to $0.62 reflects traders responding to a forecast convergence, not speculative noise.

Total volume is $10,566, all of it within the last 24 hours. That number is below $1M, which matters. Thin volume means a moderate-sized bet can reprice this contract sharply before resolution. Liquidity at $54,754 provides some cushion, but this market is not deep. One well-funded trader with a strong weather model opinion could move the needle before June 22 noon.

• YES climbed from $0.46 to $0.62 on June 21, a 5% single-session move tied to weather model alignment around the 92-93°F band.
• The 1-hour price change is flat at 0.0%, suggesting traders have settled into current pricing ahead of resolution.
• Volume below $1M means price is sensitive to new forecast data or a large directional bet before market close.
• Liquidity at $54,754 is the deepest layer in this contract, providing some price stability but not immunity to sharp moves.
• Trader sentiment leans bullish: 61.5% YES versus 38.5% NO, consistent with the current price.

Lines Analysis: What the Miami Forecast Is Saying

The National Weather Service Miami forecast for June 22 has been centering on the low-to-mid 90s. That range puts the 92-93°F bracket squarely in the probability sweet spot. Miami’s climatological average high for late June is near 90°F, so a reading two to three degrees above normal is well within the envelope for this time of year, especially during an active heat pattern. The data doesn’t care about the politics of climate debate. Miami in late June runs hot, and this year’s setup is not unusual for the season.

What makes NO real is simple math. Miami’s high on any given late-June day has a meaningful probability of clearing 93°F. The 94-95°F bracket exists on this market at a non-trivial price for a reason. If a sea breeze fails to develop or arrives later than usual, afternoon temperatures can push past the 93°F ceiling. Conversely, a well-timed onshore flow could cap the high at 91°F or below, handing the win to the 90-91°F contract. The two-degree resolution window is narrow. That narrowness is the entire risk here.

• National Weather Service Miami guidance through June 22 holds near the low-to-mid 90s. Confirmation of that range before noon resolution would support the current 61.5% probability.
• Sea breeze timing is the critical variable. An early onshore flow caps the high below 92°F. A late or absent sea breeze pushes the high above 93°F.
• Any updated model runs overnight on June 21 into June 22 morning will be the last data traders can act on before resolution.
• The 94-95°F bracket is the most dangerous competing contract for YES holders. Watch that price for signals of an overshoot scenario.

Total volume of $10,566 reflects a market that traders treated as a short-duration weather bet, not a structural position. The data favors YES at current pricing, but the two-degree window and thin volume keep uncertainty real. The market is pricing uncertainty, not science. The science says Miami runs hot in late June. The uncertainty is exactly where within that hot range the thermometer stops.

LINES VERDICT

NARROW WINDOW, REASONABLE EDGE

The 92-93°F bracket has the best single probability in a multi-outcome market, but a two-degree window in a city where sea breeze timing shifts outcomes by two to four degrees is genuinely uncertain.

What the market says: 61.5% implies a moderate lean toward the 92-93°F range, not a settled call. With resolution less than 24 hours away and volume below $1M, any fresh forecast model output or weather observation could reprice this contract sharply before June 22 noon.

Key unknown: Sea breeze development timing on the morning of June 22 is the single variable that determines whether Miami’s high stays in the 92-93°F window or overshoots into the 94-95°F bracket.
