Recent National Weather Service forecasts and ensemble guidance indicate overnight lows in the mid-60s °F for Los Angeles on August 31, driven by a shift to typical southwest flow that reduces tropical moisture and allows clearer skies with moderate onshore winds. This follows several days of elevated heat and humidity from an upper-level ridge, with climatological averages near 65 °F and marine-layer development potentially enhancing cooling after sunset. Model consensus remains tight around these values, though small variations in wind speed or cloud cover could shift the minimum by a few degrees. Trader balance between the highest and lowest outcome bins reflects uncertainty in exact overnight minimums near resolution thresholds, with skin-in-the-game odds capturing this narrow forecast range.
