The Isle of Wight endured extraordinary temperatures today (Wednesday), with multiple locations recording highs of 38°C and above as a severe heatwave tightened its grip on the Island.
According to IW Met Service, Northwood recorded the highest temperature of the day at 39.3°C, followed by Carisbrooke at 39.0°C and Newport at 38.9°C. Cowes reached 38.7°C, while East Cowes recorded 38.5°C.
Given the exceptional nature of the readings, IW Met Service carried out its own verification exercise, visiting several of the hottest reporting locations with mobile monitoring equipment to compare temperatures against nearby weather stations.
The checks, conducted within 200 yards of the stations, found that while a small number of sites were reading slightly higher than the true air temperature, the vast majority were within half a degree of the independent measurements.
As a result, IW Met Service says it has a high level of confidence that most of its stations are providing accurate and reliable data, even during one of the most intense heat events ever recorded on the Island.
The final temperature map, which combines weather station observations with field measurements, shows numerous clusters of temperatures reaching 38°C and 39°C across central and northern parts of the Isle of Wight. The close grouping of these readings further strengthens confidence that the extreme temperatures recorded were genuine.
The figures come as a Met Office Red Heat Health Alert remains in force across the Isle of Wight until Friday evening, with concerns growing over the impact of the prolonged heatwave. The extreme conditions have already prompted the closure of Carisbrooke College and Medina College, with pupils set to learn remotely.
Residents are being urged to take precautions during the continuing hot spell, including staying hydrated, limiting exposure to direct sunlight and checking on elderly or vulnerable neighbours.
