Southwest, including Arizona, New Mexico and southeast California, Orrison said. Air temperatures of 110 are forecast for the U.S. Not only will it stick around for a while as weather patterns seem stuck - a sign of climate change, some scientists contend - “it may actually tend to get a little bit worse,” Orrison said, with extra heat and humidity that has NOAA forecasting a heat index around 110 by weekend. The heat dome that baked Texas and Mexico for much of the early summer has oozed its way to Florida with sunshine, little to no cooling clouds or rain, but humidity worsened by the hot oceans, Orrison and McNoldy said. Because the water is so warm, the air in Florida gets more humid and “that's making things tougher or more oppressive for people who are going to be out and about,” he said. Water temperatures across the Gulf of Mexico and Southwest Atlantic are 4 to 5 degrees (2 to 3 degrees Celsius) warmer than normal, Orrison said. He said his 95-degree pool doesn't cool him - it just leaves him wet. While the 95- and 96-degree readings were in shallow waters, "the water temperatures are 90 to 93 degrees Fahrenheit around much of Florida, which is extremely warm," said University of Miami hurricane researcher Brian McNoldy. "The water is so warm you really can't cool off." “That's incredible,” said National Weather Service meteorologist Andrew Orrison. These are about 5 degrees warmer than normal this time of year, meteorologists said. Another buoy had a reading close to 95 (35 Celsius) near Vaca Key. Water temperature near Johnson Key came close to 96 degrees (35.6 degrees Celsius) Sunday evening, according to a National Oceanic and Atmospheric Administration buoy. “We are in uncharted territory and we can expect more records to fall,” said WMO director of climate services Christopher Hewitt. Global sea surface temperatures have been record high since April and the North Atlantic has been off-the-charts hot since mid-March, meteorologists report as climate change is linked to more extreme and deadly events. Japan reported the global average temperature on Friday was half a degree (0.3 degrees Celsius) warmer than its past record hottest day in August 2016. The globe is coming off a week of heat not seen in modern measurements, the World Meteorological Organization said Monday, using data from Japan's weather agency to confirm unofficial records reported nearly daily last week by the University of Maine's Climate Reanalyzer. If that's not enough, Florida is about to get a dose of dust from Africa's Saharan desert that's likely to hurt air quality. Forecasters are warning of temperatures that with humidity will feel like 110 degrees (43 degrees Celsius) by week's end. Water temperatures in the mid-90s (mid-30s Celsius) are threatening delicate coral reefs, depriving swimmers of cooling dips and adding a bit more ick to the Sunshine State's already oppressive summer weather.
