April weather forecast
Thailand

April stands out as the zenith of Thailand's summer, characterized by soaring temperatures and a palpable increase in heat intensity. This month consistently records some of the highest temperatures of the year, with certain areas frequently experiencing their hottest days during this period.

In the northern regions, near Myanmar and Laos, the warmth is accentuated. While these areas enjoyed a temperate respite a few months prior, April sees them under the full influence of summer, with the days becoming considerably hot.

Bangkok, along with its neighboring regions, feels the brunt of the summer's peak. Daytime temperatures often fluctuate between 32°C (89.6°F) and 36°C (96.8°F), but it's not uncommon for them to rise even further. In fact, the highest recorded temperature for Thailand, a staggering 44.5°C (112.1°F), was observed in Uttaradit during April, underscoring the month's extreme heat potential.

While April remains predominantly dry, mirroring the preceding months, the end of the month might witness the earliest pre-monsoon showers. These rains, though sporadic, bring a short-lived relief from the heat. The eastern coast, adjacent to the Gulf of Thailand, might see a few more of these showers, but they don't signal the onset of the rainy season just yet.

When compared to March, April showcases a further intensification of heat. It signifies the culmination of the summer months, paving the way for the impending rainy season. As the month concludes, the increasing frequency of showers hints at the transitional phase the country is about to enter.
