Summer officially began on Friday, June 20. This marked the summer solstice and the longest day of the year. Summer will last until Monday, Sept. 22, when the fall - or, autumnal - equinox occurs.

While all Texans know to expect plenty of hot weather each summer, seasonal forecasts can give us a better idea of what to expect the next several months.

These seasonal forecasts, issued for both temperature and precipitation, are provided by the National Oceanic and Atmospheric Administration's (NOAA) Climate Prediction Center (CPC). They're based on numerous factors. One of the most important is the presence of El Niño or La Niña. This is often referred to as ENSO, or the El Niño/Southern Oscillation. These are climate patterns that can affect large-scale weather patterns over North America.

The CPC said in June that ENSO-neutral conditions were present and expected to last through the summer and, possibly, into winter.

ENSO-neutral conditions mean there's no direct influence from El Niño or La Niña.

In terms of seasonal outlooks, this means influences on weather patterns will likely come as a result of other sources, including seasonal normal or averages for a given area.

It's important to note that seasonal forecasts consider the weather over three months and certain days may vary from what the overall seasonal forecast calls for.

Summer Temperature Outlook

Much of Texas, including a majority of Oncor's service area, has a 50-60 percent chance to see hotter than average weather this summer. Parts of far West Texas, including the Big Bend region, have a 60-70 percent chance for a hotter than average summer.
