May in Srirangam is the inland-plains heat peak. Daytime 38-40C, nights 28-29C, humidity 65 percent, rainfall under 50mm but mostly as short pre-monsoon thunderstorm bursts that don't cool the granite. The Sri Ranganathaswamy Temple inner-prakaram walk compresses to 5:30am-9am and 7pm-9pm; the inner-prakaram granite courtyards hit 46-48C surface heat noon-4pm — unworkable. The Garbha Griham stays air-cooled internally but the approach corridor through the inner prakarams is the bottleneck. The 4 outer prakarams (with residential street shade) workable through later hours but the trip-defining 7-prakaram circumambulation runs at 40 percent. The temple's 24-hour ritual schedule continues unchanged; the priests and resident-Brahmin community of Srirangam (one of the oldest Vaishnavite communities in South India, several thousand families have been on the temple-side island for 800+ years) carry on. Stay in Trichy proper (12km) — Sangam Hotel ₹1,800-3k, Femina ₹1,500-2,500, homestays ₹600-1,000. International visitor load near-zero. October opens the proper return window after the NE monsoon arrives.
