**Current National Weather Service forecasts and observational data point to a peak temperature near 80–82°F in San Francisco today, driven by clear to partly cloudy skies, light northeast-to-west winds, and above-average October warmth.** This aligns with model consensus showing afternoon highs in the low 80s, well above the long-term daily average of roughly 71°F, as warmer air masses and reduced marine influence allow greater solar heating. The market’s overwhelming 95.3% implied probability on 80–81°F reflects trader confidence in these official guidance products and real-time station readings. A stronger-than-expected sea breeze or thicker stratus layer could cap the high below 80°F, while any unexpected clear-sky intensification could push readings toward 84°F or higher before resolution.
