Weather patterns across major global cotton-producing regions are diverging sharply. West Texas is experiencing intermittent showers amid high temperatures, while Brazil's second-crop cotton area remains dry, accelerating harvest progress. This combination directly influences supply elasticity for the 2026/27 season and deserves close attention from the entire textile chain.
U.S. Cotton Belt: Showers and Heat Coexist
The U.S. Southwest, particularly West Texas, has received localized showers. According to public weather forecasts, from July 7 to 11, the region will see scattered showers with temperatures near to above normal. The 6-to-10-day outlook indicates continued showers from July 12 to 16, but temperatures will rise further, especially from July 14 to 16, when they will be significantly above normal.
Showers improve soil moisture for dryland cotton, but high temperatures increase evaporation, potentially diminishing the net benefit. For West Texas, where irrigation is limited, the combination of heat and showers may create "drink and sweat" stress—much of the absorbed water is lost through transpiration.
In contrast, the U.S. Delta and Southeast regions have more favorable conditions. Additional rainfall there generally supports cotton growth. The Southeast typically receives ample rain, and extra precipitation during the squaring and blooming stages is a positive signal for yields.
Brazil: Dry Weather Aids Harvest
In the Southern Hemisphere, dry weather in Brazil's second-crop cotton area is highly beneficial for ongoing harvest operations. Dry conditions reduce the risk of boll rot and mold, preserving seed cotton quality. Brazil's cotton output has been rising steadily, and its harvest weather directly impacts global market supply pressure.
The current dry spell in Brazil means harvest progress will likely accelerate, bringing new cotton to market earlier. For international traders, this implies more concentrated supply in Q3, putting downward pressure on spot prices.
Implications for Market Expectations
These weather factors are reshaping market expectations for new-crop cotton. West Texas is a key variable in U.S. production; the interplay of heat and showers creates uncertainty in yield estimates. If high temperatures persist beyond two weeks, boll shedding rates may rise, ultimately reducing lint yields.
Conversely, Brazil's dry harvest period ensures ample supply of high-grade cotton. As Brazilian cotton increasingly challenges U.S. cotton in export markets, a smooth harvest will further solidify its share in Asia. China, the world's largest cotton importer, may adjust its procurement strategy toward Brazilian sources.
For textile mills, the focus should be not only on price volatility but also on quality differences across origins. If West Texas heat reduces fiber strength, it will affect blending choices for fine-count yarns. If Brazilian cotton harvests smoothly, raw material costs for medium- and low-count yarns may become more advantageous.
Policy and Trade Context
Beyond weather, policy factors also shape cotton trade dynamics. The upcoming USDA monthly supply-demand report will provide the first field-survey-based estimate of global new-crop production. Whether West Texas heat is adequately factored in will be a key focus.
Meanwhile, shifts in Sino-U.S. trade relations will influence U.S. cotton export pace. If Texas cotton is reduced by weather while Chinese purchases remain stable, U.S. cotton prices may find temporary support. Conversely, if Brazilian cotton floods the market at competitive prices, Chinese buyers may adjust their sourcing lists.
