Traveller notes on Ilulissat in August
Other months in Ilulissat
Ilulissat's forum flags July for the midnight sun — it doesn't fully set from mid-May into late July — and for mosquitoes, which regulars say are genuinely present through June, July and August. Boat-trip veterans recommend a windproof layer even on a mild-looking day, since the wind off the water cuts the temperature noticeably.
