The 2026 summer weather forecast just released by the Center for Climate Forecasting under the US National Oceanic and Atmospheric Administration (NOAA) shows that temperatures higher than the widespread average are forecast to appear in most of the United States, except for the Great Lakes and the Midwest region.
According to NOAA, the temperature forecast for the period June to August shows a high possibility of higher than normal temperatures in the entire West, most of the Great Plain, the downstream Mississippi basin and the eastern United States.
In which, the Northwest Pacific region is assessed to have the highest heat forecast reliability. Most of Alaska is also forecast to have higher than average temperatures.
The summer forecast of private meteorological firm AccuWeather also agrees with NOAA. Meteorologist Brian Lada of this firm said: "A hot summer is forecast to occur in most of the adjacent territory of the US in 2026, with almost no area expected to have temperatures lower than the historical average of the season.
The probability of higher than average temperatures is increasing in most of the United States, meaning the risk of prolonged heat waves and higher than average seasonal temperatures is also greater.
AccuWeather forecasts that the places experiencing the most severe heat waves include states such as California, Idaho, Montana, Nevada, Oregon, Utah, Washington and Wyoming.
According to NOAA, Oregon and Washington are in the region with the highest heat risk - which is common in summers affected by El Nino.
AccuWeather forecaster Brian Lada noted that El Nino is forecast to form in early summer and increasingly strongly affect the tropical region as well as the weather pattern across the United States for the rest of 2026.
Forecasters also pointed out that developing El Nino could increase storm activity in the eastern Pacific, while the Atlantic hurricane season is likely to be weaker than average.
In other developments, there have been signals about the Atlantic hurricane season, starting on June 1. Experts are monitoring the possibility of a tropical depression appearing off the southeast coast of the United States. Early forecast models from Europe show that a low pressure area may form off the southeast coast of the United States in the first 2 weeks of June.
However, the possibility of development is still very low and it is too early to confirm whether a storm will actually form or not.
