Direct Answer
If you’re asking what months is Dubai too hot, the short answer is: June, July, August and most of September. During these months average highs sit between 40°C and 45°C (104°F‑113°F) and humidity pushes the perceived temperature even higher. May and October can feel tolerable, especially early May and late October, but they sit on the edge of comfort.
Understanding Dubai’s Climate
Dubai, located in the United Arab Emirates, sits in a desert zone that experiences extreme temperature swings. The city’s climate is classified as hot desert (Köppen BWh), characterized by scorching summers, mild winters, and very low annual rainfall.
Two key factors shape how hot the city feels:
- Temperature - the actual air temperature measured by weather stations.
- Humidity - the amount of moisture in the air, which dramatically raises the Heat Index (the "feels‑like" temperature).
When Humidity climbs above 70% in the summer, the Heat Index can exceed 45°C (113°F), making outdoor activities risky.
Monthly Temperature Breakdown
Below is a quick snapshot of average high, low, and humidity for each month. Data is drawn from the Dubai Meteorological Office’s 30‑year climate normals.
| Month | Avg High | Avg Low | Avg Humidity | Heat Index* |
|---|---|---|---|---|
| January | 24 | 14 | 50 | 26 |
| February | 26 | 15 | 48 | 28 |
| March | 30 | 18 | 45 | 33 |
| April | 35 | 22 | 44 | 39 |
| May | 38 | 25 | 50 | 43 |
| June | 41 | 28 | 55 | 47 |
| July | 42 | 30 | 60 | 49 |
| August | 42 | 30 | 62 | 50 |
| September | 40 | 29 | 58 | 46 |
| October | 35 | 24 | 55 | 38 |
| November | 30 | 20 | 52 | 32 |
| December | 26 | 16 | 50 | 28 |
*Heat Index reflects combined effect of temperature and humidity; values above 40°C (104°F) are considered “very hot”.
When Heat Becomes Unbearable
Most locals and Tourist health experts agree that a Heat Index over 40°C (104°F) marks the point where the body starts to struggle without extra precautions. That threshold is routinely crossed from mid‑June through early September.
Two extra dangers rise during those months:
- Heatstroke - sudden rise in core body temperature; symptoms include dizziness, nausea, rapid heartbeat.
- Dehydration - loss of fluids faster than you can replace them, especially when sweating is heavy.
Even if you’re staying in air‑conditioned hotels, stepping outside for just 10 minutes in August can feel like a sauna.
How to Stay Cool When Visiting in Hot Months
If your travel dates fall within June‑September, you can still enjoy Dubai by planning smartly:
- Schedule outdoor activities early. Sunrise to 10am offers lower temperatures and milder sun.
- Use indoor attractions. Museums, malls, and indoor ski slopes keep you entertained while staying Air Conditioning‑friendly.
- Stay hydrated. Drink water regularly; carry a reusable bottle.
- Dress appropriately. Light, breathable fabrics (cotton, linen) and wide‑brim hats help.
- Apply sunscreen. SPF30+ every two hours protects against UV‑B and UV‑A rays.
- Watch for sandstorms. Though rare in summer, a sudden Sandstorm can reduce visibility and increase irritation.
Travel Planning Tips: Best Months to Visit
For most visitors seeking outdoor comfort, the sweet spot is November through March. Daytime highs stay between 24°C and 30°C (75‑86°F), evenings are cooler, and humidity is lower.
If you can handle warm weather, late October or early May provide a balance: lower crowds, off‑season rates, and still enjoyable evenings. Just remember to check the monthly forecast before booking.
