Central Thailand and its eastern provinces heat up from February to April, with maximum temperatures getting up to around 40 degrees Celsius. The wet season arrives in May and lasts until about October, with frequent but short bursts of rain and the occasional severe storm. Winter is from November to early February, with cooler temperatures but only a couple of days of actual cold weather. The northeast and northern Thailand have similar conditions, although winters are much cooler due to the mountainous terrain of this region. The best time to visit Thailand in these areas is November to February when it's cool and dry, the flowers are blooming and misty mountain fog enhances the spectacular scenery.
