February delivers 3600% more rain than June (36mm vs 0mm). That gap is the difference between planning around showers and ignoring them.
38% of the year's rain falls in February alone, so Dubai has a genuine wet season rather than evenly spread showers.
Dubai rain typically comes as discrete showers, so a compact umbrella and a flexible plan are usually enough.
Rain falls on about 7 days in February against 0 in June — the frequency swing matters more for planning than the millimetre totals.

Rain probability is the chance that at least 0.2mm falls at your location — not how long it rains. For Dubai we combine the hourly probability curve, expected volume in millimetres, and the city's own rainfall record into a single umbrella verdict.
| Factor | Weight | What it measures |
|---|---|---|
| Hourly probability | 40% | Peak and sustained chance of measurable rain across the next 24 hours. |
| Expected volume | 30% | Total millimetres, which separates a passing shower from a genuine soaking. |
| Timing & duration | 20% | When rain starts, when it eases, and the longest continuous dry window. |
| Local rain type | 10% | Drizzle, brief showers, thunderstorms or monsoon — each needs different gear. |
