Climate & Weather in Phuket

Good to Know

• No snowfall possible in Phuket due to tropical location.
• West coast beaches (Patong, Kata, Karon) experience dangerous rip currents and rough seas May–October; red warning flags are common—respect them entirely.
• East coast beaches and sheltered bays (e.g., Ao Po, Cape Panwa) remain calmer during monsoon season.
• Monsoon showers rarely last all day; typical pattern is sunny mornings, heavy afternoon showers, then clear skies and spectacular sunsets.
• September is the wettest single month (up to 19–20 rainy days); occasional stretches of 3–9 consecutive rainy days occur unpredictably.
• December–February books out months in advance, especially around Christmas/New Year; book early.
• April is brutally hot and can be exhausting; humidity peaks and water reserves visibly drop.
• May–July offer milder monsoon conditions with more sunshine between showers, plus 40–60% accommodation discounts vs. peak season.
• Weather patterns have shifted in recent years due to climate change; traditional monsoon calendars are less reliable now.
• Humidity stays high (70–82%) year-round; lowest in February (~69%).
