Los Angeles Airport Max Temperature: April 19, 2026

Los Angeles International Airport recorded a high temperature of 97 degrees Fahrenheit on April 19, 2026, according to the National Weather Service’s climatological data for the date. This reading represents the highest temperature observed at the airport on that day in recorded history for mid-April, based on available NWS records.

The temperature was measured at the official NWS observing site located at LAX, which has maintained continuous weather observations since the mid-20th century. Climatologists note that while April temperatures in Los Angeles typically range from the mid-60s to low 70s, readings approaching 90 degrees are uncommon but not unprecedented during periods of strong offshore flow and high pressure aloft.

Meteorologists with the NWS Oxnard office attributed the elevated temperatures to a combination of weak onshore flow, subsidence warming under a mid-level ridge, and dry northeasterly winds descending from the inland valleys and desert regions. These conditions limited the usual marine influence that moderates coastal temperatures in the Los Angeles basin.

The reading was confirmed through automated surface observing systems (ASOS) at the airport, which are calibrated and maintained to federal standards for climatological reporting. No equipment malfunctions or reporting errors were indicated in the preliminary data review conducted by NWS personnel.

While the April 19, 2026, temperature at LAX was notable for its date, it did not exceed the airport’s all-time April record of 100 degrees Fahrenheit, which was set on April 30, 1981, during a significant heat wave that affected much of Southern California. The NWS maintains that such extreme early-season warmth remains rare but is consistent with long-term trends of increasing spring temperatures in the region.

Climate data from the NWS shows that April average temperatures at Los Angeles Airport have increased by approximately 2.5 degrees Fahrenheit since 1950, with the frequency of days above 85 degrees rising notably over the past three decades. Scientists attribute this trend to broader regional warming patterns influenced by urban heat island effects and global climate change.

The NWS continues to monitor temperature trends across Southern California and provides daily climate summaries through its official channels. Historical data for LAX and other observing sites in the region are available via the National Centers for Environmental Information.
