McAllen is waking up Friday, October 30, under mostly cloudy skies with temperatures around 73 degrees, but the clouds are not signaling a wet Halloween weekend. The forecast turns mostly sunny and hot by afternoon, with a high near 92 and a 10% chance of rain.
Halloween Weekend Stays Hot And Mostly Dry
Saturday, October 31, should be mostly sunny and around 93 degrees, with a mostly clear night settling to about 74. Sunday, November 1, looks nearly identical, with another 92-degree high, so outdoor plans are more likely to need water and shade than an umbrella.
According to the National Weather Service Brownsville forecast discussion, drier conditions should hold from Saturday through Monday while temperatures climb into the low to mid-90s. Monday, November 2, is expected to be the hottest day in this stretch at about 93 degrees, with southeast winds of 5 to 12 mph and gusts up to 23 mph.
Front Brings Relief Tuesday Night
The latest outlook extends beyond the earlier Halloween weekend forecast: Tuesday, November 3, stays mostly sunny near 91, then a slight chance of showers arrives before midnight as a cold front moves through. By Wednesday, November 4, skies should be sunny with a cooler high near 86 and an overnight low around 64.
Coastal Flooding Remains A Beach Concern
For McAllen, the main story is heat and dry weather, but persistent onshore flow and elevated tides will keep water levels and beach erosion elevated along the Lower Texas Coast. A Coastal Flood Statement is in effect through 7 a.m. Saturday and could be extended into Sunday, so beachgoers should check for updates before heading toward South Padre Island or other coastal spots.
