Rain in Houston in Jul 2026?
7 markets · 5d
The market is pricing near-certainty for at least 1–3 inches of rain in Houston in July 2026, but sees a sharp drop-off above 4 inches, reflecting a typical summer thunderstorm pattern where a few inches are almost guaranteed but extreme totals are unlikely.
📊 Base rate: Houston's July average rainfall is about 3.2 inches, and the chance of exceeding 4 inches in any given July is roughly 30–40%, based on NOAA climate normals.
What's driving it
- • The 99% odds for above 1, 2, and 3 inches imply a strong consensus that typical July thunderstorm activity will deliver at least moderate rainfall, consistent with Houston's humid subtropical climate (no specific recent headline needed).
- • The shift to a No favorite at 56% for above 4 inches suggests traders see a meaningful chance of a drier-than-average month or a pattern that avoids heavy downpours, as no extreme weather event has been forecast yet.
- • The declining odds from above 4 inches to above 7 inches (No 72%) indicate a steep probability drop for extreme totals, reflecting the rarity of catastrophic flooding events in a single month without a named storm.
The bullish case
- • Houston's July climatology includes frequent afternoon thunderstorms that can quickly accumulate 1–3 inches, making the lower thresholds near certain.
- • If a tropical disturbance or stalled front parks over the region, rainfall totals could easily exceed 4 inches, as seen in past Julys (e.g., 2017's Harvey was August, but similar setups occur).
- • The 99% odds for the lowest thresholds suggest traders are pricing in a baseline of convective activity that often overperforms local forecasts.
The bearish case
- • The 56% No for above 4 inches indicates a majority view that July 2026 will see near-normal or slightly below-normal rainfall, avoiding the organized systems needed for higher totals.
- • Without a named storm or persistent Gulf moisture surge, typical July rain events in Houston rarely exceed 4 inches in a single month, as high-pressure ridges can suppress convection.
- • The steep drop in odds above 5 inches (No 68%) and above 6 inches (No 74%) reflects the low historical probability of extreme monthly totals outside of tropical cyclones.
What to watch
- • A National Weather Service outlook in early July 2026 predicting above-normal rainfall would boost Yes odds for the 4–6 inch thresholds.
- • Formation of a tropical depression or storm in the Gulf of Mexico during July 2026 would sharply increase the probability of exceeding 4 inches and higher.
- • A dry pattern forecast (e.g., a strong ridge) in late June or early July would push odds further toward No for the 4-inch and above thresholds.
