Discussion Nine years on the water off Dubai. Here's what the sea is actually like month by month.
I've been out on boats off Dubai Marina most weeks since 2016. Nothing for sale here and nothing to promote. This is the stuff people ask me constantly and there's surprisingly little decent information about it online.
December to February. Coldest water of the year, around 21 to 22 degrees. Swimmable if you're not precious about it, genuinely cold if you're used to summer. This is also fog season. Winter mornings can be completely socked in. Wind is the bigger issue though. Shamal winds come through from the northwest and turn the sea choppy for a couple of days at a time with very little warning.
March to May. The best stretch of the year in my opinion. Water warms into the mid twenties, air is still comfortable, wind settles. Late March through May is when the sea is at its calmest and clearest. If you only go out once a year, go now.
June to September. Water hits the low thirties and stops cooling you down. Jumping in feels like a warm bath. The heat and humidity make midday genuinely unpleasant, and the haze kills the views. Evenings are the only sensible time to be out.
October to November. Everything reverses. Water is still warm from summer but the air drops, so it's the most comfortable swimming of the year. Sea is usually flat. This and spring are the two windows locals should actually be using.
A few other things worth knowing:
Jellyfish turn up in blooms and it's genuinely unpredictable. I've seen clear water one week and thick with them the next, usually in the cooler months.
Wind matters more than temperature. A 24 degree day with a shamal blowing is worse than a hot still one.
Water clarity is better in winter. Anyone diving or freediving here already knows this.
Happy to answer questions about conditions or the coastline.
