What should I do if I see a jellyfish while swimming at Pattaya Beach?

- Stay calm and avoid touching the jellyfish, as their tentacles can still sting even if they're washed up on the shore. - If stung, rinse the affected area with vinegar or seawater, and seek medical attention if the reaction is severe. - Avoid swimming in areas where jellyfish warnings are posted, and pay attention to local advice regarding jellyfish seasons. Practical Pattaya note: Match the advice to your exact location, budget, transport and travel dates, and confirm time-sensitive details directly with the relevant provider or official source.
