Tbilisi's Climate and Your Computer: How Heat, Dust and Humidity Swings Affect Your Tech

Computers are designed for "average" conditions: a room temperature of 22–25 °C, moderate humidity, clean air and a stable power supply. Reality in Tbilisi is often different. In summer it reaches 38–40 °C outside, top-floor flats bake, dust from old streets and building sites gets indoors, in winter the heating dries the air out, and the power grid in older districts behaves unpredictably. All of this takes a toll on desktops and laptops — and working with customers all over the city, we see it every day.

Heat: the main seasonal enemy

A computer's cooling system dumps heat into the room's air. If the room is 32 °C instead of 22, every component will run 10 degrees hotter under the same load. For a computer that was already near its limits, that means throttling, noisy fans and spontaneous shutdowns. In summer the number of overheating call-outs in Tbilisi rises noticeably.

• gaming PCs and laptops start lowering their clock speeds and slowing down;
• laptops on laps and sofas overheat to the point of shutting off;
• dried-out thermal paste that coped in winter gives up in summer;
• laptop batteries wear faster and can swell;
• routers and network gear in cupboards and alcoves freeze and reboot;
• hard drives in overheated cases degrade faster.

Dust

Tbilisi is dusty: a dry climate, heavy traffic, endless construction and renovation, old buildings. Dust settles on heatsinks, fans and boards, acting like a blanket that blocks cooling. Construction dust is particularly harmful: it's fine and abrasive and can contain cement particles that absorb moisture and promote corrosion. Computers in flats near main roads or building sites need cleaning more often — sometimes every six months rather than once a year.

Dry air and static

In winter, with the heating on, indoor humidity drops and static electricity builds up. That raises the risk of damaging components during any work inside the computer or when plugging in devices. Dry air also makes dust settle more readily.

Temperature swings and condensation

If you bring a laptop in from the cold winter street into a warm flat and switch it on straight away, condensation can form on the cold parts inside. Droplets of moisture on the board and contacts are a direct route to short circuits and corrosion. The same can happen in summer when equipment moves from an air-conditioned car into a hot, humid room. Give the device 20–40 minutes to reach room temperature before switching it on.

The power grid

Brief outages, dips and voltage spikes are especially common in older districts — Sololaki, Mtatsminda, Chugureti, Avlabari — and in buildings with worn wiring. The risk of surges rises during thunderstorms. The consequences for equipment:

Protection means a quality surge protector, plus a UPS for desktops, servers and network equipment. If mains problems are frequent, it's worth having an electrician check the wiring.

How to extend your equipment's life in local conditions

1. Service desktops and laptops every 6–12 months: cleaning, new thermal paste, fan checks.
2. Don't put the tower next to a radiator, in direct sun, in a closed cubby or on a carpet.
3. Use a laptop stand and avoid working on soft surfaces.
4. Plug equipment into a surge protector, and important devices into a UPS.
5. Let devices warm up or cool down to room temperature after moving them.
6. During home renovations, cover your equipment or move it out of the room.
7. Back up regularly — a sudden outage or surge can destroy data.

A real example

A small hotel in the Old Town called us in July: the reception computer and the router were freezing several times a day, and guests were complaining about the Wi-Fi. The equipment sat in a closed wooden cabinet with no ventilation, and the computer hadn't been cleaned since it was bought. We cleaned and serviced the computer, moved the router somewhere with airflow and connected everything through a UPS. The freezes stopped, and the next power cut in August passed without the hotel even noticing.

A word about direct sunlight, too. Many people put their laptop or monitor by the window, and in summer the sun heats the casing to temperatures at which batteries and screens degrade quickly. A laptop left in a parked car in August can exceed 60 °C — dangerous for both the battery and the data on the drive. Keep devices out of direct sun and never store them in a car during the hot months.
