Colombo Weather Outlook: Thunderstorm Risk Today, Then a Hot, Hazy Stretch With Spotty Showers

Colombo is starting the day under cloudy skies with warm, tropical air already in place. The key near-term feature is an afternoon thunderstorm window today, followed by several days of sun filtered through high clouds and consistently hot daytime temperatures. If you’re planning outdoor time, the practical takeaway is to treat today as the most weather-disruptive day of the next week, then expect mostly stable heat with occasional pop-up showers later in the period.

Current snapshot (as of this morning ET): cloudy and warm in Colombo, with temperatures around the upper 70s Fahrenheit.

What happened: today’s setup favors afternoon storms

Today’s forecast points to some sun early, then a turn toward thicker cloud cover with a couple of afternoon thunderstorms. In Colombo, that pattern typically means a muggy buildup, then fast-changing conditions: brief heavy downpours, lightning risk, and localized street flooding in low-lying areas if storms stall.

Today (Friday, Feb. 6 ET)

• High: 89°F

• Low: 75°F

• Most likely disruption: afternoon thunderstorms

Behind the headline: it’s less about “cold fronts” and more about tropical timing

Colombo’s week ahead is a classic tropical rhythm: persistent warmth, plenty of moisture, and brief rain episodes that tend to cluster in the afternoon when daytime heating peaks. The forecast’s repeated “sun through high clouds” language is a signal that the atmosphere stays warm and humid, but not locked into a multi-day washout.

That matters because people often plan around “rainy day vs. sunny day,” when the real decision point in Colombo is usually “what time will the rain hit?” A day can feel sunny and usable for hours, then flip quickly during a short storm burst.

What to watch: lightning, heat stress, and short-fuse downpours

Three practical impacts stand out this week:

• Lightning risk today: If thunderstorms fire this afternoon, postpone exposed outdoor activities during the storm window. Tropical storms can look manageable until lightning suddenly increases.

• Heat and humidity: With highs near 88–90°F most days, the strain comes from humidity rather than temperature alone. Expect the “feels-like” factor to run higher, especially midday.

• Localized flooding potential: Even “a couple of storms” can dump heavy rain in a short period. If you’re commuting, allow extra time during afternoon and early-evening periods on the days flagged for showers.

What happens next: likely scenarios for the week

• If today’s thunderstorms are more widespread than expected, you could see slower traffic and brief power interruptions in pockets, but conditions should settle back into the hot, hazy pattern quickly.

• If showers on Saturday and late next week trend heavier, expect a slight uptick in afternoon disruptions without a meaningful drop in temperatures.

• If cloud cover thickens more than forecast midweek, daytime highs may dip by a degree or two, but the overall feel will remain warm and humid.

If you tell me whether you want this for travel planning (airport runs, beach time, city walking) or for daily commuting, I can translate the forecast into the best time windows by day—still using ET dates.
