Key Points
- In 2026, Ramadan falls in winter: fasting lasts around 11 hours in London — one of the shortest of the decade.
- In 2033, it will fall in July: fasting will reach 18+ hours in the UK.
- Ramadan moves forward approximately 11 days each year in the Gregorian calendar.
- Equatorial countries like Indonesia fast ~12-13 hours year-round, regardless of season.
- A dehydration level of just 1-2% impairs cognitive function (Johns Hopkins Aramco Healthcare, 2024).
- 73% of French Muslims fast during Ramadan (IFOP, 2025).
The Prophet ﷺ said: "Whoever fasts in Ramadan with faith and hoping for its reward, all his previous sins will be forgiven." (Bukhari no. 1901)
That promise is constant — regardless of the season. Yet the physical conditions vary enormously. In 2026, you fast for under 12 hours in London. In 2033, you will fast for nearly 18 hours under the same latitude.
Understanding these differences helps you prepare wisely. Here is your complete guide.

Ramadan in Winter: Benefits and Challenges
A winter Ramadan is often called the "easy Ramadan". That reputation is partly deserved — but it hides real challenges.
From Islamic tradition: Ibn Rajab al-Hanbali (14th century) wrote that the believer recognises in each season a gift from Allah ﷻ. A short fast is a facilitation granted, not a reason to reduce spiritual effort.
Benefits of a Winter Ramadan
Short days. In London in 2026, Fajr (dawn) sounds around 6:20 am and Maghrib (the breaking of the fast) arrives around 5:30 pm. You fast approximately 11 hours — comparable to a regular working day without lunch.
Long nights for worship. After Maghrib, you have nearly 13 hours before the next Fajr. Time for Tarawih (night prayer), Qiyam (night vigil) and Quran reading is generous.
Less physical fatigue. Cool temperatures reduce sweating. The risk of dehydration headaches is minimal. Your body manages the absence of water more easily.
Challenges of a Winter Ramadan
Cold dampens motivation. Short evenings encourage staying indoors. Attending the mosque on a rainy night takes conscious effort.
Iftar arrives while you are still at work. With Maghrib at 5:30 pm, you may be commuting or still in the office. Iftar logistics require planning ahead.
Suhoor is close to waking time. With Fajr at 6:20 am, Suhoor is around 5:50 am. Little time remains between eating and the dawn prayer.
Ramadan in Summer: Benefits and Challenges
A summer Ramadan is demanding. In London in 2033, Fajr will sound around 3:00 am. Maghrib will not arrive until 9:30 pm. Fasting will last close to 18 hours.
Key stat: A dehydration level of 1 to 2% of body weight is enough to reduce cognitive performance and concentration (Johns Hopkins Aramco Healthcare, 2024). During a hot summer day, this threshold can be reached by midday without water.
Benefits of a Summer Ramadan
A more intense purification. Greater physical effort is often associated with greater spiritual reward. Imam Ahmad ibn Hanbal considered summer fasting particularly meritorious.
Short but precious nights. Between 9:30 pm and 3:00 am, only about 5 hours remain. Every minute spent in worship carries special weight.
Festive Iftar evenings. Breaking the fast at 9:30 pm under a still-bright sky creates a memorable, communal atmosphere.
Challenges of a Summer Ramadan
Physical fatigue is real. Working, studying or driving during 18 hours of fasting puts strain on the body. Adjusting your pace is essential.
Suhoor is in the middle of the night. Rising at 3:00 am to eat, then going back to sleep, disrupts your circadian rhythm.
Nights are too short for long prayers. Between Maghrib, Isha, Tarawih and Suhoor, little time remains for sleep. Time management becomes a challenge in itself.
Extreme high latitudes. In Edinburgh, Oslo or Reykjavik, the sun barely sets in June. Special calculation methods apply — the Nisf al-Layl (midnight) method or the Nearest Latitude method. Local Islamic councils in the UK have issued guidance on this.
How to Adapt to a Summer Ramadan
Here are concrete strategies, supported by medicine and Islamic tradition.
1. Optimise Suhoor
Suhoor (the pre-dawn meal) is a recommended Sunnah. The Prophet ﷺ said: "Have Suhoor, for there is blessing in it." (Bukhari no. 1923)
In summer, this meal must be strategic:
- Prioritise low glycaemic index foods: oats, pulses, wholegrain bread. They release energy slowly over 6 to 8 hours.
- Hydrate well: 500 to 700 ml of water between Maghrib and Suhoor.
- Avoid salt and fast sugars: they accelerate dehydration.
2. Adapt your Iftar
Breaking the fast with a date (tamr) and water follows the Sunnah. Then wait 15 to 20 minutes before the main meal. Your stomach, after 18 hours at rest, needs this transition.
3. Manage your sleep
With Fajr at 3:00 am, nocturnal sleep is fragmented. Two options:
- Sleep early (8 pm to 3 am), then stay awake until Fajr.
- Take a midday nap (Qaylula) between Dhuhr and Asr. This practice is recognised in prophetic tradition.
4. Reduce physical exertion
Avoid intense exercise between noon and 5 pm in summer. If you exercise, do so in the 30 minutes after Iftar, when hydration is possible.
5. Use digital tools
The Muslim Expert app sends automatic reminders for Suhoor and Iftar, tailored to your city and your country's calculation method. In summer, these early alerts prevent you from missing Fajr.
The Spiritual Dimension Remains Identical Regardless of Season
The Quran is clear on this: the purpose of fasting is not suffering, but piety (taqwa).
"O you who believe! Fasting is prescribed for you as it was prescribed for those before you, so that you may become pious (muttaqun)." (Quran 2:183)
The reward is not proportional to the duration of the fast. It is proportional to sincerity (ikhlas), patience (sabr) and gratitude (shukr). An 11-hour fast lived with full awareness is worth infinitely more than an 18-hour fast lived mechanically.
The key hadith: "Night prayer during Ramadan, with faith and hoping for the reward of Allah, erases past sins." (Bukhari no. 2009)
This promise mentions neither summer nor winter. It speaks of faith and intention (niyyah).
Equatorial Countries: A Constant Duration
A little-known reality: Indonesian, Malaysian or Nigerian Muslims do not experience these seasonal variations.
Close to the equator, these countries have near-constant day length throughout the year. In Jakarta (Indonesia), fasting lasts between 12 and 13 hours in all seasons.
This means:
- Ramadan there is always of similar intensity.
- The community does not experience the wide variability of northern countries.
- Seasonal adaptation strategies are less necessary.
For Muslims of the Indonesian or Malaysian diaspora living in Europe or Australia, this can be a surprising discovery. Moving from a 13-hour fast in Jakarta to an 18-hour fast in Amsterdam represents a genuine physiological challenge.

FAQ
Why does the fasting duration change every year? The Islamic (Hijri) calendar is lunar: it has 354 days per year, 11 fewer than the Gregorian calendar. Each year, Ramadan falls 11 days earlier. Over about 33 years, it cycles through every season.
Is the reward of fasting greater in summer than in winter? Islamic tradition does not establish an automatic hierarchy. Some scholars consider that greater effort in summer increases merit. Others emphasise that quality of intention (niyyah) takes precedence over duration. Consult a trusted scholar for personal guidance.
What if I live in Scotland or Scandinavia where the sun barely sets in summer? Specific methods apply to high latitudes: the Nisf al-Layl (midnight) method or the Nearest Latitude method. Many European Islamic councils have issued rulings on these cases.
Can I make up missed fasting days if I am ill during a summer Ramadan? Yes. The Quran explicitly provides for compensation: "Whoever among you is ill or on a journey — a number of other days." (Quran 2:185). Illness and travel are legitimate excuses recognised by all four legal schools.
How do I find the exact Fajr and Maghrib times in my city? The Muslim Expert app automatically calculates your prayer times based on your GPS location and the calculation method recommended in your region.
Summary
A winter Ramadan offers short days and long nights. It supports nocturnal worship and eases physical management. A summer Ramadan demands more from the body — but some scholars see extra merit in it.
In both cases, the essential remains the same: faith, intention, and seeking closeness to Allah ﷻ. The Quran is clear: the purpose of fasting is taqwa (piety), not suffering.
Whether you fast 11 hours or 18 hours, the Iftar you break with a date and a sincere prayer carries equal weight before Allah ﷻ.
Ramadan Mubarak! May Allah ﷻ accept your fast and grant you sincere piety.
