Tips for Post-Typhoon Dive Planning
- Wait at least 3 days after the typhoon passes
- Sites near rivers (Ito, Hirasawa) recover slower
- Open-ocean sites (Kerama, Yonaguni) recover fastest
- Check our AI forecast too (note: accuracy drops after typhoons)
- Same-day reports from dive shops are always the most reliable
