Wellington June 11 High Temp: 14C at 44.5%

Wellington’s weather market is flashing mixed signals heading into Thursday. The 14°C outcome carries a 44.5% implied probability as of June 10, but the contract has shed nearly 10% in a single hour. That kind of intraday move on a hyperlocal temperature market almost always traces back to fresh forecast data landing in trader feeds.

The market question asks: what will the highest temperature in Wellington be on June 11? The 14°C outcome sits at $0.45 YES and $0.56 NO, with resolution set for June 11 at 12:00 UTC. Total volume has reached $22,740, with $19,041 of that trading in the last 24 hours alone.

How the Wellington June 11 Temperature Contract Works

This contract resolves YES if Wellington’s official maximum temperature on June 11 hits exactly 14°C. The resolution source is the market itself, calibrated against observed meteorological data. Every other temperature band has its own parallel contract, including 13°C, 15°C, 12°C, 16°C, and ranges at the extremes.

• YES ($0.45): Wellington records a maximum of exactly 14°C on June 11.
• NO ($0.56): Wellington’s maximum falls at any other temperature on June 11.

For the NO side to pay out, the Wellington maximum simply has to land anywhere other than 14°C. That sounds easy, but the market is pricing uncertainty across at least eleven possible outcomes. When probability spreads across that many buckets, a 44.5% share for a single outcome is actually a meaningful lean. The question is whether overnight forecast revisions will shift capital toward 13°C or 15°C before the window closes.

Momentum and Market Signals

The momentum composite here is firmly bearish over the short window. The 14°C contract dropped 9.5% in the last hour and 2.0% over 24 hours, with a trend score of 57.63. That combination suggests forecast models updated recently and moved probability mass away from 14°C, most likely toward an adjacent band. Wellington sits at 41 degrees south latitude in early June, which is mid-autumn there. Afternoon highs in the low-to-mid teens are climatologically normal for this period, so the spread is tight and small forecast shifts carry real weight.

Volume tells an interesting story. Total volume of $22,740 is thin by most standards, and $19,041 trading in 24 hours means the market is moving fast on limited depth. Liquidity stands at $29,322, which slightly exceeds total volume. When volume is this low, a single well-timed bet can shift price sharply, so treat the current 44.5% figure as a live estimate, not a settled consensus.

• The 9.5% one-hour drop in the 14°C contract is the sharpest signal: new forecast data appears to be moving money toward an adjacent temperature band, likely 13°C or 15°C.
• The 24-hour decline of 2.0% confirms the directional pressure is sustained, not a momentary glitch.
• A trend score of 57.63 reads as mildly bullish by the index but contradicts the price action, suggesting the scoring window and the latest moves are not yet aligned.
• Volume below $1M means this market can reprice dramatically if a single large participant enters with a strong view on the overnight forecast.
• Open interest is listed at zero, which suggests most positions are short-duration and traders are not holding through the resolution with large committed stakes.

Lines Analysis: Wellington’s Tight Temperature Window

Wellington in early June sits in a climatological corridor where afternoon highs cluster between 12°C and 16°C. The 14°C outcome attracting nearly half the probability in an eleven-outcome market reflects that this band is genuinely the modal forecast. MetService and international numerical weather prediction models typically converge on a narrow range for Wellington’s June temperatures, and 14°C sits comfortably in the middle of that range. The bearish price action over the last hour suggests a model run pushed the probability mass slightly cooler or warmer, but not by enough to collapse the 14°C share entirely.

The real risk for the 14°C contract is a clear-sky, calm-wind scenario that lets temperatures drop a degree lower than expected, landing at 13°C, or a warmer-than-forecast northerly flow pushing the max to 15°C. Wellington is famously windy, and wind direction on any given day can shift the afternoon high by two or three degrees. That meteorological variability is the core reason NO carries a 55.5% lean despite 14°C being the single most probable outcome. The NO side wins if any other temperature band resolves, and with eleven alternatives, that statistical advantage is structural.

• MetService forecast for June 11 is the single most important input. Any update showing a clearer northerly or southerly pattern will reprice adjacent contracts.
• International model agreement (GFS versus ECMWF) on Wellington’s maximum will either consolidate the 14°C lead or fracture probability across 13°C and 15°C.
• Wind direction at Cook Strait matters significantly. A northerly fetch warms Wellington; a southerly cools it.
• Morning temperature at Wellington Airport serves as a leading indicator for the afternoon maximum. A cold start narrows the ceiling.
• Any significant weather system tracking through the Cook Strait region overnight could shift the entire probability distribution by two degrees or more.

Here’s what the measurements are telling us: the 14°C outcome is the rational modal pick for mid-autumn Wellington, but thin volume and the multi-outcome structure mean the market is pricing uncertainty, not science. Total volume of $22,740 is not deep enough to treat this price as a refined probability signal. The data currently favors 14°C as the single most likely outcome, but the NO side holds a structural edge simply because the alternatives collectively dominate.

LINES VERDICT

MODAL OUTCOME, STRUCTURALLY CHALLENGED

Wellington’s 14°C outcome is the most probable single result for June 11, but the multi-outcome market structure means NO remains the better statistical position. The market is pricing meteorological uncertainty, and Wellington’s wind variability makes any adjacent band a credible alternative.

What the market says: A 44.5% implied probability means traders see 14°C as the most likely single temperature but give a collective 55.5% chance to every other outcome. With resolution in less than 24 hours and volume below $25,000, this price will move sharply if the next forecast model run shifts the center of the distribution even one degree.

Key unknown: The MetService or GFS model update overnight on June 10 into June 11 is the single data point that will reprice this contract. If that run shows a strong northerly or southerly wind pattern, expect capital to shift to the 15°C or 13°C contracts before the June 11 resolution window opens.

Scientific Context: Wellington’s June Temperature Range

Wellington’s climatological record for early June shows afternoon maxima most frequently falling between 12°C and 15°C. The city’s exposure to Cook Strait means wind is the dominant variable, not cloud cover or synoptic pressure alone. Historical June maxima at Wellington Airport cluster tightly, which is why prediction markets on daily temperature here tend to concentrate probability in a narrow two-to-three-degree band. The data doesn’t care about the politics of any forecast model; Wellington’s geography forces a tight distribution and makes adjacent outcomes nearly as probable as the modal one. Events that would move price before the June 11 resolution include any MetService special weather statement for the lower North Island or Wellington region, or a significant shift in overnight model consensus moving the predicted high by more than one degree.

What is a 44.5% probability?

It means the market estimates a 44.5 in 100 chance Wellington hits exactly 14°C on June 11. With eleven competing outcomes, this is actually a strong single-outcome lean, but the remaining 55.5% is split across many alternatives.

What does it take for NO to win?

Wellington’s maximum must land at any temperature other than 14°C. That includes 13°C, 15°C, 12°C, 16°C, and all extreme-range outcomes. The NO side benefits structurally from the multi-outcome format.

What data would move this market most?

A MetService forecast update or international model run showing the June 11 Wellington maximum shifting from 14°C to 13°C or 15°C would reprice this contract sharply. Wind direction forecasts are the key variable to track.

When does this market resolve?

Resolution is set for June 11 at 12:00 UTC. With Wellington 12 hours ahead of UTC in standard time, this corresponds to midnight Wellington time ending the June 11 observation window.

Is the volume reliable enough to trust the price?

Total volume of $22,740 and 24-hour volume of $19,041 are both below the threshold where prices reflect deep market consensus. A single large trade can shift the probability by several percentage points on this contract.
