Tips for a Wedding on an Extremely Hot Day

The Enemy Nobody Plans For

Every couple getting married in summer in Portugal creates a backup plan for rain. Almost none create one for extreme heat.

And yet, with heatwaves becoming increasingly frequent (temperatures above 35°C that IPMA records every summer) heat is probably the most underestimated factor in summer wedding planning.

As a wedding videographer, I’ve filmed weddings at 40°C at 4pm. I’ve seen brides with melting makeup before the ceremony. I’ve seen grandparents feeling unwell in the sun. I’ve seen suited guests fleeing to the shade during cocktail hour. And I can guarantee: heat doesn’t just ruin comfort, it ruins moments that should be beautiful.

This article is the practical guide I wish every summer wedding couple would read.

Rule Number 1: Ceremony Time Changes Everything

If there’s one single decision that can save a wedding on a hot day, it’s this: don’t hold the ceremony before 5:30pm.

Between noon and 4pm, the sun is at its highest and most aggressive point. An outdoor ceremony during this window, even with partial shade, will be uncomfortable for everyone, couple, guests, and vendors.

From 5:30pm onwards, the temperature starts dropping, the sun softens, and the light enters the famous golden hour, that period between 5:30pm and 7pm when the light is warm, soft, and cinematic. It’s the best light of the day for video and photography, and the time when guests can actually be outdoors without suffering.

If family tradition demands an earlier ceremony, consider an indoor ceremony in an air-conditioned space, with the outdoor cocktail in the late afternoon.

Guest Comfort: The Details That Save the Day

Guests won’t say aloud that they’re dying of heat, but on video, it shows. Red faces, sweaty foreheads, expressions of discomfort. These are details that, if not prevented, ruin the film’s shots.

Water and fresh lemonade stations. Placed at strategic points, ceremony entrance, cocktail area, near the dance floor. Ice-cold water bottles with mint or fruit are an elegant and functional touch.

Fans. Placed on the ceremony chairs. Besides being practical, they can be personalised with the couple’s names and become a lovely keepsake. On video, guests waving fans during the vows is a charming visual.

Planned shade. If the ceremony is outdoors, ensure guest seating is in the shade, natural (under trees) or created (awnings, parasols). The altar can be in the sun if the couple prefers, but guests need to be comfortable.

Artisan ice cream. An ice cream cart at the cocktail is one of the most successful ideas at summer weddings. On video, it’s a playful, colourful moment that relieves the weight of formality.

The Dress and the Heat

I’ve filmed brides who by 3pm, before the ceremony even started, were uncomfortable because of the dress. And I understand why, a traditional wedding dress with layers of tulle, a tight bodice, and a train wasn’t designed for 35°C.

Discuss cooler options with the designer or seamstress:

• Light fabrics: Organza, chiffon, and light tulle breathe significantly better than heavy satin or mikado
• Open necklines and backs: Besides being fashionable, they allow ventilation
• Second look: More and more brides have one dress for the ceremony and a lighter one for the party, shorter, cooler, more practical for dancing

The groom deserves attention too. A linen suit instead of wool, a lightweight cotton shirt, and the social permission to remove the jacket during the party. On video, a relaxed groom with rolled-up sleeves dancing conveys more energy than a jacketed groom sweating in silence.

The Impact of Heat on Video

As a videographer, heat creates real technical challenges:

The shimmer. At very high temperatures, hot air creates a visual distortion, especially in long telephoto shots. It’s the same effect you see over hot tarmac. Positioning in shade and using angles that avoid hot surfaces solves the issue.

Makeup. Heat melts foundation, runs mascara, and creates excessive shine on skin. This directly affects video close-ups. I always recommend a makeup artist who uses waterproof products and does touch-ups before each key moment.

Batteries and equipment. Extreme heat drains batteries faster and can cause cameras to overheat. I work with extra batteries and equipment rest breaks, but it’s a factor couples rarely consider when requesting 12-hour coverage in mid-August.

Planning Is Love

Planning for heat isn’t pessimism, it’s care. Check the IPMA forecast in the wedding week and have alternatives prepared. On Casamentos.pt and Zankyou, couples who mention heat in reviews always say the same thing: “I wish we’d thought about this sooner.”

The best decisions you can make:

• Ceremony after 5:30pm
• Shade zones and ice-cold water everywhere
• Light fabrics for the couple and guests (communicate casual elegant in the invitation)
• Air-conditioned indoor spaces as backup
• Brief the DJ and photographer/videographer on the hottest hours to avoid

Heat doesn’t have to ruin the wedding. With planning, it becomes just part of the summer landscape, and in the film, the golden sunset after a hot day is one of the most beautiful settings I know.
