Weather Service Sees No L.A. Heat Break. Downtown Is Forecast to Hit 99 Wednesday.

The National Weather Service point forecast, updated Aug. 22, 2026, puts downtown Los Angeles near 99 on Aug. 26 and Woodland Hills at 109, with no easing date inside the seven-day period.

Downtown Los Angeles is forecast to reach 99 degrees on Wednesday, Aug. 26. That is six degrees hotter than Saturday's forecast high. The number comes from the National Weather Service's own point forecast for downtown Los Angeles, issued Aug. 22, 2026. That product was last updated at 11:57 a.m. PDT. What it does not carry is a date for the heat to end.

The question was put to a thread on the r/LosAngeles forum, which asks when the region might get a break. The post did not load for this desk on Aug. 22, and is linked here in full. The answer from the record is that inside the seven-day forecast there is no break.

This is the week that lands on people who work outdoors, on households without air conditioning, and on anyone who counts on the night to cool a room down.

Seven days downtown, none of them cooler

The point forecast covers the zone the Weather Service labels Los Angeles County Inland including Downtown Los Angeles. It runs through 6 p.m. PDT on Aug. 28. The daytime highs read as follows.

• Saturday, Aug. 22: near 93, sunny.
• Sunday, Aug. 23: near 94.
• Monday, Aug. 24: near 94.
• Tuesday, Aug. 25: near 96, "sunny and hot".
• Wednesday, Aug. 26: near 99, "sunny and hot".
• Thursday, Aug. 27: near 99.
• Friday, Aug. 28: near 98.

Overnight lows climb across the same stretch in the same product. They go from 70 degrees Saturday night to 75 by midweek.

The downtown Los Angeles gauge read 93 degrees shortly after noon on Aug. 22. Humidity was 34 percent, and the heat index matched the air temperature.

The San Fernando Valley runs a full step above that. The same forecast product for Woodland Hills gives a high of 103 on Aug. 22. For Wednesday, Aug. 26, it gives 109.

The forecast high for downtown on Saturday was 93. The forecast high for Woodland Hills on the same day was 103.

What the forecasters wrote

The Area Forecast Discussion from the National Weather Service office in Los Angeles/Oxnard points away from relief rather than toward it. It was issued at 10:56 a.m. PDT on Aug. 22. Its synopsis says additional warming is possible next week as high pressure builds in from the southeast.

The short-term section, timestamped 9:41 a.m., says models show little change through at least Monday. Then comes this, in the discussion's own words:

"increasing heat along with weakening onshore flow which cloud [sic] push some areas into heat advisories and possibly warnings in some areas"

Read that language for what it is. The discussion hedges. Heat "possibly" pushing some areas into advisories is a probability statement about days that have not happened yet, not a schedule. A seven-day forecast tightens or loosens with each issuance. This one was itself an updated release.

Two things are not established here. Whether Los Angeles County has an active heat advisory or excessive heat warning in force for the days above is not carried in the forecast products read for this piece. Neither is the county's current cooling-center list or its posted hours.

Readers who need a cooling center should check the county's own posting rather than a forecast page, which does not carry it.

What the record supports is narrow and useful. As of the Aug. 22, 2026 issuance, the Weather Service's downtown Los Angeles forecast climbs for five straight days. It never returns to Saturday's number before the product runs out.
