Prediction markets show traders are essentially certain that Wellington's temperature will not exceed 13°C on February 28. The leading market, asking if the high will be 13°C or below, is trading at a 100% probability. In practical terms, this means the collective intelligence of thousands of bettors sees no real chance of a warmer day. The market is heavily focused on the cooler outcome, with over $160,000 wagered across several related temperature questions.
This high confidence stems from Wellington's reliable late-summer climate and specific short-term forecasts. Late February in Wellington is typically mild, with average highs around 19°C. However, the city is famously windy and changeable, and forecasts for this specific date likely show a cool southerly flow or marine layer keeping temperatures down. The market's certainty suggests weather models are in strong agreement about a cool day, with no sign of a northerly wind that would bring warmer air. Historically, temperatures above 25°C in Wellington are rare even in summer, so a forecast capping at 13°C aligns with a plausible, if chilly, summer day.
The only key date is February 28 itself. The market will resolve shortly after the day ends based on the official reading from Wellington International Airport's weather station, sourced from Wunderground. The primary factor to watch is the actual weather on the day. A last-minute shift in wind direction to a warm northerly could theoretically change the outcome, but the market's current odds show traders believe such a shift is extremely unlikely at this short forecast range.
For short-term weather events, prediction markets are often quite accurate, especially in the final 24-48 hours. They aggregate not just public forecasts but also the judgment of many individuals who may monitor hyper-local conditions. However, the 100% probability is a market artifact, not a meteorological certainty. It indicates extreme confidence, not an absolute guarantee. Weather has inherent unpredictability, but for a simple metric like a daily high temperature, these markets typically perform well. The main limitation is that they reflect current expectations, which could shift slightly with unexpected weather changes.
The prediction market shows near-certainty that Wellington's highest temperature on February 28 will be 13°C or below. The "Yes" contract for this outcome trades at 100 cents on Polymarket, implying a virtual 100% probability. With $164,000 in total volume, this is a highly liquid and confident market consensus. A 100% price indicates traders see no plausible scenario for the temperature exceeding 13°C.
This extreme confidence is rooted in Wellington's late-summer climate and real-time weather data. February 28 falls at the end of the Southern Hemisphere summer. Wellington's average high temperature in February is approximately 20°C, but the city is notorious for its volatile, windy conditions influenced by the Cook Strait. The market's decisive move to 100% strongly suggests that finalized meteorological forecasts for the specific date, likely from the cited Wunderground source, have confirmed a cool, overcast, or windy day. Historical patterns show that Wellington can easily see daytime highs suppressed into the low teens, especially with southerly winds, making a 13°C ceiling a reasonable forecast for a cool summer day.
At a 100% price, the market considers the outcome resolved. The odds would only change in the event of a catastrophic data error or market manipulation, which is highly improbable given the volume and the use of a specific, automated public weather source (Wunderground for Wellington Intl Airport). The resolution is imminent or past due, meaning the official high temperature for February 28 has almost certainly been recorded and verified. Any discrepancy between the reported data and the market's interpretation would be the sole catalyst for price movement now.

This prediction market focuses on forecasting the maximum temperature at Wellington International Airport on February 28, 2026. The market resolves based on the highest temperature recorded at the official weather station for that specific date, with data sourced from Wunderground's historical records. Wellington, New Zealand's capital, experiences a temperate maritime climate characterized by moderate temperatures, frequent winds, and changeable weather patterns. The specific date, February 28, falls late in the Southern Hemisphere summer, a period when Wellington can experience its warmest conditions, though these are often tempered by the Cook Strait winds. Interest in this market stems from both meteorological curiosity and the practical implications of weather forecasting. Participants may analyze long-term climate trends, seasonal forecasts from agencies like NIWA, and historical temperature distributions for late February to inform their predictions. The outcome offers a precise, measurable data point that reflects both typical summer weather and potential anomalies influenced by broader climate patterns or specific weather systems like high-pressure zones or northerly airflows.
Wellington's climate records provide essential context for temperature predictions. The city's official temperature records have been kept since 1862, originally from the Wellington Botanical Garden and later from Kelburn and the airport. The Wellington International Airport station became a primary climate site in the latter half of the 20th century. Historical data shows that February is typically Wellington's warmest month, with an average daily maximum temperature of 20.2°C (68.4°F) based on the 1991-2020 climate normal period. The absolute maximum temperature ever recorded in Wellington was 31.1°C (88.0°F) on February 6, 1934, at the now-closed Thorndon site. For the specific date of February 28, historical extremes provide a range of possible outcomes. In recent decades, the highest temperature recorded on February 28 at the airport was 26.5°C (79.7°F) in 2019. The lowest maximum temperature recorded on this date was 14.8°C (58.6°F) in 1993. These historical extremes establish the outer bounds for reasonable predictions, while the distribution of past temperatures informs probability estimates. Climate change has introduced a long-term warming trend. NIWA's data indicates New Zealand's annual average temperature increased by 1.26°C between 1909 and 2022. This trend suggests that temperature records for any given summer date are more likely to fall in the warmer part of the historical distribution in the 2020s compared to earlier decades.
The specific maximum temperature on a given day has tangible consequences for Wellington. High temperatures affect public health, particularly for vulnerable populations, and influence energy demand as residents use cooling systems. Tourism and outdoor events scheduled for late summer, including the final days of the Wellington Cup racing carnival and outdoor festivals, are directly impacted by weather conditions. The hospitality and retail sectors often see increased activity during warm summer days. From a scientific perspective, individual daily maximums contribute to larger datasets used to monitor climate change. Consistent recording of temperatures at official stations like Wellington Airport allows researchers to track warming trends, validate climate models, and understand local microclimates. An unusually high or low temperature on February 28, 2026, would be analyzed in the context of prevailing climate drivers like El Niño or La Niña conditions, potentially offering insights into seasonal forecasting accuracy. For the prediction market itself, the outcome represents a test of collective forecasting ability against both numerical weather prediction models and climatological averages. Success or failure in predicting this specific metric informs discussions about the wisdom of crowds applied to meteorological phenomena.
As of late 2024, NIWA's seasonal climate outlook indicates that neutral conditions are expected for the 2025-2026 summer, following the 2024-2025 El Niño event. This suggests neither a strong warming nor cooling influence from the Pacific Ocean climate driver for the upcoming season. The latest Intergovernmental Panel on Climate Change (IPCC) assessment reports confirm ongoing global warming, which provides background warming pressure. Specific operational weather forecasts for February 28, 2026, will not be available until approximately one week before the date. Until then, predictions must rely on climatology, long-range seasonal outlooks, and analog years with similar climate driver states.
The maximum temperature in Wellington typically occurs in the mid-to-late afternoon, between 3 PM and 5 PM local time (NZDT). This timing can be influenced by sea breezes and cloud cover, which often develop later in the day and may limit further warming.
Forecast skill for a specific day's maximum temperature decreases rapidly beyond about 10 days. For a date months ahead, predictions rely on climatological averages and the expected state of large-scale climate drivers like ENSO. Seasonal outlooks can indicate whether a month is likely to be warmer or cooler than average, but cannot predict daily specifics.
The official climate station is situated on airport property. Its specific location and exposure are standardized to meet World Meteorological Organization guidelines, ensuring measurements are comparable over time. The site is away from immediate heat sources like tarmac to avoid artificial inflation of temperature readings.
In the event of a station failure, MetService and NIWA have procedures for estimating missing data using nearby stations or model reanalysis. For the purpose of this prediction market, the resolution source is Wunderground's record for the Wellington Intl Airport Station; if no data is available from that specific source, market resolution would follow the platform's rules for missing data.
NIWA's temperature trend analysis shows Wellington has warmed at a rate broadly consistent with the national average over the past century. However, its coastal location and persistent winds modulate extreme temperatures, resulting in fewer very hot days compared to inland regions of the country.
