The potential temperature increase could lead to warmer-than-average conditions for late September in San Francisco. While the forecasted high of 74°F (23.3°C) is within the climatological range, any offshore wind events or a complete burn-off of the marine layer could push temperatures into the upper 70s or beyond. This could result in discomfort for residents unaccustomed to higher temperatures and may increase energy demand for cooling systems. However, the likelihood of extreme heat, such as the record 93°F (33.9°C) set in 1980, remains low based on current guidance.
