**Trader sentiment centers on coastal moderation amid a broader California heat wave setup.** With the National Weather Service highlighting high pressure building inland from August 1–2, interior valleys face extreme heat risks, yet San Francisco’s marine layer and persistent sea breeze are expected to limit the highest temperature to the mid-70s. Long-range guidance and monthly forecasts place typical early-August highs near 68–72°F, but recent model consensus shows slight above-average warmth (around 73°F seasonal signal) as onshore flow weakens modestly. This positions the 76–77°F bin as the modal outcome at 35.5% implied probability, followed closely by 74–75°F (24.5%) and 78–79°F (22%), reflecting uncertainty in exact marine-layer depth and timing of any warming. Stronger fog or breeze would favor the lower bins, while any temporary offshore shift could push readings into the upper 70s. No major forecast shifts have occurred in the past 48 hours, keeping probabilities clustered tightly around near-normal coastal conditions.
