Thai Beach Safety Checker
Rip currents, jellyfish season, flag colors, and lifeguard hours by beach.
What this solves
Thai beaches have specific hazards by season. Patong has a notorious rip current during southwest monsoon. Box jellyfish appear in Chon Buri and Pattaya beaches June–September. Some beaches have lifeguards only 09:00–17:00. Flag colors indicate swimming conditions but vary by beach.
How to read results
Each beach-month combination gets a hazard score (1–5), jellyfish warning, rip current risk, and lifeguard presence. Always swim between flags and within designated hours. Red flag = do not swim; yellow = caution; green = safe.
Limitations
- Specific flag colors are set daily by lifeguards, not by month.
- Some beaches (Pattaya, Patong) have lifeguards only in peak season.
- Jellyfish warnings depend on local conditions, not always announced in advance.
FAQ
What does a red flag mean?
Do not enter the water. Strong currents, dangerous surf, or marine hazards. Thai lifeguards set the flag daily based on conditions.
When are jellyfish a risk?
Box jellyfish appear on Chon Buri / Pattaya beaches June–September. Avoid swimming at dawn and dusk. Vinegar is the standard first aid — apply liberally if stung.
What if I get caught in a rip?
Don't fight it — swim parallel to shore to escape the current, then back to land. Most rips are narrow (5–10 m) and will release you.
