Working in Summer: Get Ready for the Heat

March 24, 2026 - 12:00 AM

Thailand and scorching weather have always gone hand in hand—but this year, the heat is taking things to a whole new level. Temperatures are expected to soar up to 43°C in several northern provinces, according to the Meteorological Department. The 2026 hot season is predicted to be even hotter than last year, stretching from late February to mid-May, with its peak blazing through April and May. [1]

With this extreme rise in temperature, many organizations, especially government agencies, have rushed to introduce new measures to help people continue working in hot weather safely and efficiently. One of the most impactful policies is the Work From Home directive, allowing civil servants and state‑enterprise employees to stay home to reduce energy consumption and avoid the harsh midday heat. Offices that remain open have been instructed to set air‑conditioning to 26°C and cut unnecessary travel, including pausing all international study trips during this period. [2]

When the weather refuses to cooperate, adjusting how you work becomes essential. Here’s your go‑to guide for working through summer without letting the heat drain your energy or performance!

Top Tips to Stay in Peak Performance While Working in Summer

1. Make the Most of the Work From Home Policy

Those who are given the green light to work remotely, you gain a huge advantage; the comfort of your own temperature‑controlled space. No harsh sun, no sweltering commute, and more flexibility to rest and recharge. It’s the perfect setup for staying productive while working in hot weather.

2. Keep Your Workspace Cool and Heat‑Smart

If you still need to go to the office or work outdoors, set up your environment wisely:

  • Keep the AC at 26°C—a balance between comfort and energy efficiency
  • Use sun‑blocking curtains or reflective film
  • Avoid outdoor tasks during the hottest hours: 11 AM–3 PM

A smart workspace can help you sustain energy even when the heat outside is unforgiving.

3. Hydrate Like Your Productivity Depends on It

Hot weather speeds up dehydration, which means your body loses more water than you think. To stay alert and energized:

  • Bring a water bottle everywhere you go
  • Drink small amounts frequently
  • Add electrolytes on days when you sweat more

Staying hydrated is the secret weapon for working in summer without feeling drained.

4. Reshape Your Schedule for Heat‑Proof Productivity

When temperatures peak, your body feels it. So, align your workflow with your energy levels:

  • Do deep‑focus tasks in the early morning or evening
  • Switch onsite meetings to online ones whenever possible

A heat‑friendly schedule helps you stay sharp even when the temperature soars.

5. Take Micro‑Breaks to Refresh Your Brain

Extreme heat affects focus and cognitive performance. So, short breaks—just 3 to 5 minutes every hour—help reset your mind, prevent burnout, and keep your productivity steady throughout the day.

Summer May Be Strong, but We’re Stronger

This year’s summer may be hotter and harsher than ever, but that doesn’t mean your work has to suffer. With the right strategies—hydration, smart scheduling, a cool workspace, and the flexibility of remote work—you can continue working through summer without missing a beat.

Surely, we can’t control how high the temperature climbs, but we can control how we prepare, adapt, and protect our well‑being.

So, instead of simply enduring the heat, let’s outsmart it. Because no matter how intense the season gets, summer doesn’t get to decide the quality of your work—you do.
